I have a '91 240sx Fastback with 270,000 miles on it. Original engine. I've been driving it since 1991 and I love it. Back in 2005 I got tired of my exhaust rattling, rusting, and rotting so I had my mechanic make me a custom exhaust with an HP Racing stainless steel muffler. I'm happy to report that it's still solid with no rust, and no holes after six years! The only problem is I have been pulled over 3 times and ticketed twice because of the noise. I had my mechanic install a resonator, but it is still kinda loud. I recently got a ticket just because it is an aftermarket exhaust. The officer told me aftermarket exhausts are illegal in Virginia.

I'm tired of dealing with cops, but I don't want to go back to the crap stock exhaust I had before. Any suggestions? Has anyone ever tried to put an Infiniti exhaust on a 240sx? The Q45 looks similar. Are they better quality? Will they fit?

I have attached some pics of my exhaust swap so you can see what I have.

I would try NICO's very own AZHitman, with his BRM exhaust, I think its as close to stock as you can expect, Ive got a lil review in my sig, and there is a huge thread here: new-exhaust-for-the-s13-s14-240sx-t48608.html Nothing but positive reviews

you could get a varex exhaust system or something similar. there is a butterfly valve that you can open or close. for some systems, it is even quieter than stock when the valve is closed.

Any exhaust system with a "valve" for our cars is a POS.

A properly-designed system can be straight-through, with no restrictions and no "gimmicks" and still be VERY quiet.

If you're really having trouble with the police then you might just have to run stock, or 2.25" pipe with a huge resonator and good muffler like AZhitman offers.

BTW, what is wrong with those valves that allow you to partially close the exhaust to make a quieter note?

Hey AZhitman, I think I bought a second hand exhaust of yours. How can I tell if it is your handy work? It looks like all your photos.

The problem with an obstruction in the exhaust stream is it's a band-aid "fix" that doesn't really work well. If you want to choke down your exhaust with a silencer or a valve, just leave the properly-engineered stock system on it. I chuckle every time I see a big ol' 3" system with a silencer with a 1" hole in it. Congratulations, you fail. :)

As far as the system you bought, it's hard to tell without seeing it.

If you love it with all your heart, it's probably something we built. ;)

Ahhhh! Good ol' Virginia..... A buddy of mine just bought an s13 with 2.5 inch piping to the factory muffler. It's somewhat quite putting around town yet really Honda-ish when you get on it. I wouldn't recommend that... Since you're in Va and our exhaust laws only apply to imports (sarcasm), I would just go back to the oem exhaust. Then again, you've only received 2 tickets in 6 years? That's pretty good compared to most here!

I would look into the BRM as suggested above. It looks super close to a factory muffler with the factory chrome "tips". Plus It sounds great.

Perhaps that 'after market exhasts are illegal' ticket should be fought.

Unless the fed gov has no say in VA...

Some guy on a subie forum has the same issue.

http://forums.nasioc.com/forums/showthr ... ?t=2128408

He plans on fighting and has some good ideas about how to go about it.

When I was pulled for my exhaust a couple of years ago, the cop told me ANY exhaust modification was illegal and let me go after I told him I had a "silencer".. A friend of mine was pulled for having a big muffler and was warned not to drive the car unless the oem exhaust was put back on. Another friend of mine had a Buddyclub spec II on his sr and was pulled just about every other time he drove the car.. He got 2 tickets in a seven month period. I feel that it has to do with the cop and how he feels about it as well. Va is wierd..

Yeah, I just looked up VA exhaust laws and it says pretty much stock equipment or stock equivalent (http://leg1.state.va.us/cgi-bin/legp504 ... +46.2-1049). You could probably get away with BRM 2.25" w/ 22" resonator and dual tip exhaust or something similar.

Get a Blitz Realize TT. Yeah I know they are hella expensive but are only like 95db's. Not too bad. Looks "stock" . I've seen Honda Accords running around here with 5 inch tips, picnic table wings and sound like $h!t . I hope they get pulled over before I do. We will see once the car gets out the shop. If I get pulled over a lot for my exhaust I'm going Blitz Realize TT or something that looks "stock" .

I loved my sleeper setup before this one with Stock alloys. Nobody really messed with me since I drilled a hole in my stock muffler. Sounded like crap but effective. As performance upgrades go on cars, the sleeper and quiet exhaust kinda gets thrown out the window lol. Of course it is only imports that cops ever mess with. :tisk:

He wasn't ticketed for a sound violation, so quiet exhaust wasn't his issue. He was ticketed for 'Non stock part'. So naming off 'quiet' exhausts does not help.

No thats very serious and true. Its bull crap. I have a friend that had a wak late 90s Mustang GT with gutted cats, no mufflers and straight an Xpipe. He had it for 5 yrs plus and never got pulled over for too loud of an exhaust, and it was loud. Im suprised that you even got pulled over for that simple exhaust. Do you live in Fairfax County?

I have gotten 4-6 exhaust tickets in the 3 years Ive had my 240, but mine I can understand. Its big and loud and I hate it with all my heart.

I agree that the silencer crap is crap. A cop told me once that I needed that to not be bothered by cops. They just make it sound like a constant powdery fart so I just say F it.

Thanks for all the responses. I'm giving you guys an update. By the way, I live in Manassas. When the Prince William County police officer pulled me over, we were both sitting at stop lights on opposite sides of the road. He watched me turn through the intersection and began to follow me. I wasn't speeding and had not been drinking, but it was midnight. Bingo!!! He followed me for a while before pulling me over. He must have been bored. I am a Neighorhood Watch coordinator, and I go to meetings at the police station frequently. Nobody has ever said anything about my exhaust at the meetings. I know that's not an excuse for breaking the law, but I thought I'd mention it.

Fenris, I agree with your post. I also looked up the law ( http://leg1.state.va.us/cgi-bin/legp504 ... +46.2-1049 ) and it does state that the exhaust can be "comparable" to standard factory equipment...and... "An exhaust system shall not be deemed to prevent excessive or unusual noise if it permits the escape of noise in excess of that permitted by the standard factory equipment exhaust system". To me that means that it can't be louder than Nissan's specs, not Virginia's specs, so it seems that noise is the real issue here. Also, the code does not mention emissions. In my opinion, emissions should be more important than noise. My ticket just says that the exhaust is "inadequate". What makes it inadequate? The noise??? My stainless steel exhaust will last longer than the car. My best buddy is a Fairfax County police officer. He has ridden in my car and says that it is too loud. He suggested that I compare stock prices to stainless steel prices.

So enough ranting. I've probably said too much. I did some research on pricing. This is just parts, not installation. Here's what I came up with so far:

Sheehy Nissan of Manassas
stock catback
$688.20 (you've gotta be kidding me!!)
gasket $18.10


Champ Auto in Manassas
$97.61 intermediate pipe and resonator
muffler and tailpipe $195.15 (NOT stainless steel)


BRM
new-exhaust-for-the-s13-s14-240sx-t48608.html
Pricing - S13/S14 pricing (with resonator) is as follows:

2.25"aluminized $400, stainless $500

2.5" aluminized $400, stainless $500

3.0" aluminized $460, stainless $560

ADD $30 FOR DUAL TIPS.

Shipping (48 states) is $45. Shipping to Canada is $75.

Catalytic Converter - A high-flow cat (any size) can be added to any system for $135, and can be purchased separately for $155. This is a direct bolt-in catalytic converter, in the stock length, complete with flanges and hardware.

here in va, i drive all over from like farmville to richmond and places all in between....and this is the honest truth, it is illegal to have anything but the OEM exhaust, all aftermarket is illegal, even dual exhaust on a truck that didnt come with duals from the factory is illegal....stacks on a turbo diesel are illegal, everything.
now, due to literally everyone having somthing done to the exhaust, duals on trucks, stacks, fartcans, straight pipes...its one of those non enforceable laws, so its left up to the officers diescretion. if he thinks its too shiney, ticket. if he thinks its too loud, ticket. if he just plain doesnt like your effin car or your face, tickets.
i got plenty of fix-it tickets in my s13, in my crx, in my talon....i never once got a ticket in my straight piped f100, my piped dodge ram, my stepped exhaust chevelle 355 with huge tires on the back and would chop loud as hell down the road.

everyone knows how things are.
import? ticket, just expect to get one if youre running somthing on the car that shouldnt be there.
domestic? if its loud as hell but nice, no ticket.
if you have either and its a s***, ticket. :rotfl

A couple thoughts:

dB testing on exhaust systems = a joke. ANY company that publishes a number for their system should lose their business licence, because it's a sham. There's literally a THOUSAND other factors that impact sound pressure levels at a certain distance from a car, so they're quite simply full of crap.

Those of you getting citations REALLY need to get active in the SEMA Action Network with me and help get these silly laws overturned (or clarified). Any citation that prohibits non-factory parts on a car can easily be defeated in court if you're willing to take it to that level and do your homework.

NO system that improves performance will be AS QUIET as stock. But I'm convinced that our 2.25" dual-tip resonated system is as close as you can get in an S-chassis system.

I agree. Its a stupid rule. Harley Davidsons roar by my house and that is loud, especially if their riding like a Hells Angel. This happens alot in May and June, around Memorial Day, sometimes at 2am and it wakes everyone up. Now how come a simpleass exhaust like that thats barely different from stock, not even intended to be loud, be illegal? A cop told me once that all people like me with big exhaust only rev engine in front of my house and late at night. Im definantly not that guy. Oh yeah then he searched my car and called dirt in my carpet weed flake leftovers. Fairfax County man...

Greg Ive always wanted to fight that law because it pisses me off, but I didnt think it would go anywhere not to mention time and cost.

actually the varex system just redirects the flow. it doesnt restrict it. you ahve the option of choosing a straight through or a conventional exhaust. its the same has switching back and forth from a stock exhaust system to a high flow one.

Here's another update. I decided to go to Nissan's web site and look around. I found a NISMO catalog.

http://www.nissanusa.com/nismo-web/Nism ... g-2010.pdf

In the 240sx section there is a catback exhaust system for the S13. I printed that page of the catalog. I took it to Sheehy Nissan here in Manassas and asked them to order it for me.

Went to my court date today and showed them the receipt from Nissan. Case dismissed...you are free to go. :D
