Greg! shipping was fast! he said 8 biz days, i ordered it sunday the 16th, got here monday the 24th.(a week).

i am very...VERY happy with the sound, at idle it sounds just like stock exhaust, even driving lightly(~2-2.5k rpm) it doesn't sound that much louder than stock, after 3k rpm...well it just sounds mean, mind you, this is a 3" with 22" resonator and dual tip.

there was a fitment issue, but it doesn't have to do with the piping sitting low, cause the piping sits right where its supposed to be, like the stock exhaust.(i'll have to take pics, but the piping is quite up, can barely see it from the back like other pics), also the hanger before the muffler hanger fit right in.

can't forget to add, the mid rpm's feel better, overall rpms feel better.(might be an illusion, but it does feel like it pulls harder)

hey.still new here. just recently bought my purplish s14 from fiznat. nice car and everything, 600 miles on engine, 2.25" aluminized brm exhaust with 22" resonator, and a few other goodies. my biggest gripe with the car though, is the obnoxiously loud exhaust and its poor fitment. i think i may have gotten a lemon of an exhaust. while it does sound awesome, it's nowhere near quiet. at 3000rpm it would sound louder than the stock exhaust at redline. pictures of nice fitting exhausts here have the resonator straight and parallel with the chassis. mine angles down, and at the lowest point there is only 3" of clearance. i'm about to get s.techs with agx's/koni's, and that puts it down another 1.5", leaving only 1" of clearance when there's a couple people in the car. living in nyc with all these potholes, that's just un-realistic. Any advice guys? sorry if i sounded a bit pissed. it's just that i had a much lenghthier post of the same topic that didn't post and was lost to cyberspace :'(

greg, do you know what could be causing the problem? i've checked all along the exhaust for leaks. as for the fitment issue i'll try to get some pics of it this weekend, but basically the bend before the muffler is angled very low. Funny thing is there's also close to no clearance between the rear anti-roll bar and the pipe, but it hasn't hit it yet, so i'm happy about that

The sound of a stock exhaust at redline is practically just the sound of air coming out, its more engine noise than anything. Try to get some pics up of the low clearance

[wa-chiss]

has anyone thought that the nice sound could just be the magniflow muffler? I'm not saying anything bad about the brm system. Accually my friend has it on his S13 and it fits PERFECT. Stainless, 22" res., highflow cat, and best of all, the Dual tips. we think they look the best. Anyway, i put the magniflow on my Xterra the sound levels are the same. quiet and deep at idle-2500rpms but if i step on it it screams. Just something i noticed today

[p0onsta]

not likely at all.it's all in the tuning of the exhaust. take one exhaust from one car and put it on another and it will never sound the same.

the xterra has a different displacement engine, with 6 cylinders firing, so that alone will yield a deeper/different tone/grumble at any rpm.

sound waves of certain freq.s flowing into the resonators at different spots etc makes it all different. i'm sure if somebody took greg's system and relocated the resonator, it would sound vastly different.

although on a personal note, anything past 1krpm on mine is pretty loud. sorry about the continuous complaints..lol. i promise to get pics and sound clips up soon.

and the stainless brm had a 22" resonator option???

and something else just came to mind...since aluminized steel and stainless steel have different qualities when it comes to resonant frequency and how well they reflect waves, i wonder how different the stainless exhaust sounds compared to the aluminized steel... sound clips please?

[zanetran]

hey greg im gonna call you today so yea ! i got back from another trip

[wa-chiss]

I don't know if the stainless has a 22" option. it's just what he told me. he could have fibbed a little. i just know it's sweet looking

I too have an aluminzed system with a 22" resonator, but mine is a 2.5" system , which should really be louder than a 2.25.

pardon the belt squeal.

[p0onsta]

thanks for the vid clip kdashy.how high did you rev? exhaust sounds nice. mine sounds exactly the same at idle with slightly more grumble. and when you were revving, on mine that sound would come from ~1750rpm.

on a side note, i love how my exhaust goes POP POP POP like an anti-lag system as my revs come back down. it's not loud or anything, but is very interesting. anybody else get this?

[KDashy]

I think I went to around 4k for the highest rev.

I too get the pop pop sound when the engine is slowing down in gear, at about 1500 rpms.

[wa-chiss]

a lot of cars with aftermarket exhaust will do that. Don't really know why though. Try shifting as soon as your rpm's hit the cutoff, i do in my Xterra and it pops LOUD AS HELL about 2 or three times before i can let the clutch out again. Sounds cool when I'm in a tunell or in between some high walls.

[Tonkasat]

Hey can I get that clip of the BRM exhaust? I was wondering how it sounded. I'm thinking of getting one. Do you have a body kit on your car? Ever think of doing a Silvia conversion?

-thanx

[SuperDiesel]

I like the dual tip exhaust system. It looks super diesel!

Welcome aboard SD!!!!

The aluminized steel system MAY be a tad quieter, as the metal is thicker (and a bit heavier) than stainless.

Also, we can put a 22" resonator on ANY system, they're just not made of stainless. Not that big of a deal - if it rusts in 5-7 years, cut it out and I'll sell you a replacement for $70.

Only stainless resonator is 14".

By the way, BRM had a HUGE month in July - We sold 15 systems, or one every 2 days!

I think I need to come up with a special deal for our 500th system (like a freebie)....

[one85_db]

got my new exhaust on today (2.25" with 22" res. and duel tips) all i can say is WOW! fit perfect on my S13, and the sound is incredable. Still a tad bit loud... but it pulls much harder during the mid and high RPM range. We also cut off that dumb tow hook between the tips; what a stupid location for a tow hook!!! what we did on my S13 was to remove the lower bolt and cut it off just above it with a plasma cutter; cant even tell it was ever there, and if i need it put back on in the future for some unforseeable reason then i can doo...!!!

Hey Greg, I just sent you a email about ordering one of your catbacks. Looking forwad to getting my invoice.

[240on430]

any sound clips of a take off and cruise?

[M.O.B]

Hey Greg, I just sent you a email about ordering one of your catbacks. Looking forwad to getting my invoice.

x2 Im ready

[newTo40]

Well just ordered mine. Thanks for the great service Greg! Ill put up reviews when i get mine in!

[MdaddyS]

... the first one sounded good. We'll see if the next one fits.

[Arrow]

Hey guys, I've got one question that hopefully someone can answer w/o too much dificulty:

I am looking at buying a 3" system and would like to know if it will bolt directly up to the factory cat or not... and for that matter if the 2.5" would either... thanks in advance guys!

[sideways in 916]

have you thought about making silencers for it? only thing im worried about is the sound and attracting too many cops =x it sounds great but you can hear it from pretty far away it seems...

[JustinStrife]

A silencer on a BRM???

That just kills the whole purpose of having the free-flowing exhaust. You might as well stay stock.

[sideways in 916]

silencers hardly rob any power at all and its not like youd have to have one.... just for those who dont wanna be heard from a half mile away.

[anumeric]

Greg got my exhaust and just installed it the other day. Fits like a glove. Sounds quite diesel. I'm very happy with it, looks, fits, and sounds great. If the dual tips were about a inch or so shorter then it would be perfect. But that is just a matter of perference. Only thing though is that I'm mad at myself that I didn't order a highflow cat with it at the same time. I will be order a high flow from you shortly though.

thankswei

[AZhitman]

silencers hardly rob any power at all .

VERY untrue.

A silencer is a metal insert that reduces the effective interior diameter of your exhaust, usually down to 1" - 1.5". Creates a mess of backpressure and sounds terrible...

[Arrow]

hey greg, did you catch my last question? about if the 3" exhaust would bolt up to the stock cat or not? just curious...

trying to decide which to go w/ the 3" or 2.5" since I plan on going turbo eventually with a goal of 250 to 300 whp (final goal) and I know that the 2.5 starts to top out in that range... so it's basically preference now... just curious if I can postpone getting a highflow cat for a while and just bolt up a 3" to my stock one (if I go w/ the 3").

Thanks in advance!
