Who's interested in a full Versa catback exhaust?

Postby AZhitman » Wed Aug 20, 2008 6:58 pm

Yep - The company that's built over 1,000 catbacks for the 240sx and over 500 for the Sentra has just released their system for the Versa hatch!!!

NOTE: This is NOT a "axle-back" wannabe system - This is a full catback, from the catalytic converter to the rear bumper...

No ricey sound, no lame fartcannon tip, no weak crush bends, no fake stainless steel, no stamped flanges, and no cheap ebay components!

Unlike the competition, ours includes gaskets and hardware. Considering gaskets and hardware can cost another $30, there's something to factor into the overall cost when making your comparisons.

Would possibly be interested to support you Greg. If I can force myself to spend money on the Versa.

I'm in. Looking at your other pricing 400 and up is pretty good.

Got pix and a video!

My kit is the polished Magnaflow muffler with no res (it isn't loud at all)

2.25" mandrel bent piping. All bolt up (mine is all welded but for shipping purposes it will have 2 flanges)

You will have the option for a polished or non polished muffler (both come with a tip)

Option for a resonator or not (not sure if it cost extra)

On to the pix!

Old exhaust

Buh buy stillen!

No exhaust

Test fitting polished muffler

The polished and non polished mufflers look exactly like the stillen muffler (Stillen uses magnaflow mufflers)







Mandrel bent



Non polished muffler has the same tip as the polished







Welding



Final fitment









I have to give it to Greg, this company's attention to detail is amazing. I got there at 8:30 and didn't leave until 2:30

After they weld it up they start the car check for leaks and they spray paint all the welds with rustoleum.

And now for the video Quality isn't the best but whatever.

Not one bit of farting!

Turned out AWESOME!!!

The tone with a resonator will be a little quieter and deeper, with less of the popping on deceleration.

Looks like we have a winner on our hands!

that sounds REALLY nice.

theres one thing i have to ask though. Since these fit the Hatchbacks, will they fit the Sedans? i know for a fact that the tenabe exhaust does NOT fit on the sedans without modification. the sedan is a little longer than the hatch therefore doesn't fit properly and the exhaust sits too far behind the car.

i was wondering if this will have the same affect on the sedans since you guys fitted the exhaust on the hatch. thanks!

First I've heard of them being different lengths. They would probably have to do a separate version for the sedan then. A test fit would have to be tried to be sure.

If it's of good quality (won't rust apart after a year), sounds good, stays quiet during cruising, and has a decent price tag, I'd be interested. I don't want a farty exhaust that's loud because the system just has a too open muffler with no resonator. I say if you're gonna design an exhaust, use a muffler that actually sounds good and the longest resonator that will fit.

ill take a picture of my exhaust tmrw. but i have the same setup, 2.25 piping, no res, and magnaflow muffler. you will notice that the tip comes straight off the muffler in codereds pix, mine on the sedan there had to be another pipe welded to the end of the magnaflow because it sat too far back and higher up so theres quite a gap difference between sedan and hatch.

You cant get the best sound quality out of a digital camera. There is no farting and it's very deep.

This is NOWHERE NEAR the same as the axle-back. An axle-back system offers very little performance improvement... it basically just changes the muffler.

Ours begins at the catalytic converter. The piping is smoother and straighter (less bends), adds a straight through resonator (to quiet it down without affecting flow), and ends up with a straight-through, free flowing muffler a the end.

Again, there is NO comparison between wehat we're building and an axle-back. You want an axle-back, just go cut off your factory muffler and weld on an aftermarket one. But don't expect any increase in performance.

Also, CodeRed's system is significantly louder than what the rest will be, because he opted for no resonator.

I want the catback..But i have an auto Anybody gotta an opinion on adding an catback onto a auto car? cause i know it sounds much better on a manual car, just not sure how itll sound with an auto...

No difference whatsoever... unless you like riding around in neutral revving your motor...

The sound (when driving) will be the same.

It's all bolt on. No need to get anything welded.

As for the HP gains we haven't dyno'd the car yet.

We're seeing average gains of 12hp on 2.4 and 2-liter engines. I'd be inclined to bet 10 is a realistic and safe number for the Versa.

If the stock system is as restrictive as I think it is, it may do even better.

nice.

I got the aem intake, when i get the catback will it "connect" very well together?

It depends on how restrictive the stock exhaust was in the first place. On some cars, it's not the piping. It's the muffler itself restricting exhaust flow. A 1.8 liter 120 HP 4-cylinder doesn't exactly need a full blown free flowing exhaust to perform though which is why I question the gains of the cat-back.

An intake and a catback exhaust have nothing to do with each other. However, increasing intake means it's not a bad idea to increase exhaust flow as well.

It's designed to bolt right to your catalytic converter.

Here's some good info on the ins and outs of exhaust systems... Hopefully this will help everyone comprehend how it works and what the different components are:

FREQUENTLY ASKED QUESTIONS:

What is a resonator, and do I need one?

A resonator is critical for a street-driven car. Here are some basic, layman's terms explanations:

There are 3 common ways to reduce sound in an exh system: Resonator (reflected waves), muffler (wave absorbtion and reflection) and silencer (reflected waves and restriction). BRM uses a resonator and a straight-through muffler on its systems for the S13 and S14.

Resonator is a straight-through chamber sized larger than the inlet / outlet, sometimes with baffles or slots (think old-school cherry bombs). Tuned properly (through placement, diameter, length, shape and location) it will actually cancel out certain frequencies as the sound waves collide, yet does not impede flow.

Muffler is a chamber with internal walls (think of a maze) that the gasses travel through. As the waves pass through, they are disrupted and "chopped up" and the sound is absorbed by the surrounding packing (think of an insulated room). Can be restrictive depending on design - if it's a straight-through design, it will not impact flow and actually makes very little impact on the sound (primarily "fine tunes" the exhaust note).

Silencer is a conical obstruction placed in the exhaust system which reflects sound waves back against themselves, cancelling certain frequencies, much like a resonator. But it also works by restricting the amount of flow, thereby reducing sound levels. May as well shove a potato in your tailpipe and bore a small hole in it.

What size should i get?The most commonly-asked question by far... Short answer - The KA and SR both function VERY well with 2.5" exhaust. Many will tell you that a turbo car needs a 3" exhaust to function properly, to which we say, NOPE.

Keep in mind that 2.5" is a significant increase in size over the stock system, and there are far less bends / restrictions in our system. Unless you're pushing 400+ hp, there's really no need for 3". However, we understand that some folks prefer a larger pipe diameter, so if that's what you want, then we'll build it for you!
