Cat-Backs: Value, Performance & Sound

Hope all is good Camaro clansters!

Looking to upgrade exhaust, and I think the best option is to just upgrade to a Cat-Back system. What I'm after is the best performance for my 1LT possible, and nice sound as well. After consulting and reading through these forums, here are my priorities:

1. Performance: the system that helps my car release those exhaust gases the quickest, least back pressure possible, and hopefully gain a little hp/tq as result. From what I've read, a 2.25" tube system would be first choice, since the smaller diameter helps the gases exit faster and reduce backpressure. Next best would be 2.5", but nothing larger than that.

2. Sound: not looking for loud and annoying. Just a nice deep tone.

3. Looks/Finish: Don't care too much for "bling" finish. More interespted in peformance and ease of install---as long as it's lighter than the stock exhaust, .

4. Value: of course, best price possible.

Now here are some of the systems I'm looking into that meet the above criteria:

Solo Mach-X-LFX: http://solo-performance.com/v6-mach-...v6-convertible
This one is 2.25", so probably offers the best performance w/ least backpressure, sounds good, and great price.

The MBRP cat-back: http://www.phastekperformance.com/MB...t-s7020304.htm
This system is 2.5" like most others, but sounds good, and good price as well.

Corsa 2.5" Cat-back: http://www.************.com/cocatbaexfor2.html


Any advice/suggestions are greatly appreciated! Those of you who know about the 2.25" vs 2.5" theory (which of these should provide better performance?), please share your thoughts!

Just came accross Pyres Cat-back: http://www.phastekperformance.com/20...aust-ss-v6.htm



Very low price. They look decent, seem like they can save lot of weight vs stock, and should sound Ok.
------------------------------

There's also ARK. They had a great 4th of July special. Just missed it. They claim nice performance gains http://www.arkperformance.com/Produc...SM0403%2D0010D

Hear you bro. Especially in our South Florida heat and humidity, we gotta help our cars breathe.

As far as warranty issues, not really. I've checked with several dealers, and they all said that axle-backs don't void, and cat-backs either, unless GM can prove that the engine was damaged directly because of exhaust upgrade--extremly difficult.

Check this out: http://www.camaro5.com/forums/forumdisplay.php?f=70 here's a warranty thread on this site that discusses these issues, and very informative.

If u want, you could just get the GM exhaust upgrade, made by Borla. It's an axle-back, and GM covers it, and Chevy dealer installs them.

Found interesting article: http://www.aptuned.com/blog/increase...easy-ways.html

basically, it argues that the most restrictive components of exhaust are mufflers and cat. Therefore, no need to speed money on cat-back system. Just replace mufflers (axle-back), and get high flow catalytic converter and save $$$.

If that's the case, the best would be system that upgrades mufflers & includes high flow cat converters. (unless the Camaro stock cats are very good and not really worth upgrading)

Got an interesting PM. The person says that i should just buy the muffler myself, and then have it installed at some shop, instead of buying a system from a Company. he says that these companies just buy mufflers, put their label on it, and sell them for high prices to us. He says we can get the same mufflers they get, but save lots of money. http://shop.advanceautoparts.com/web...ip2HomeClicked=

Those Magnaflow, Flowmaster, and Dynomax mufflers on pages 2& 3 look exactly like the ones being sold to us from these very same companies, but I don't know if there's any truth to the story. If its true, then I can get two $79 performance mufflers, and get them installed at local shop for $75, and upgrade my exhause for $220-250, instead of paying $600 for axle-backs from these companies that use these very same $80-90 mufflers

I personally would rather just buy an axel back. It's already assembled with stainless tips welded on, brackets in place, etc. It's a savings yes, but not necessarily huge. Then I can install it myself in my spare time since exhaust shops are never open when I'm off work

I just sent a message to get a quote about a CAI/Scoop/Bottle Relocation and MRT V2.0 axel back.

@SimpleGreen: Those MRTV2 are great from what I've read. What I'm looking at is if there's a significant gain in performance in cat-back vs axle back. For example, the ARKs claim 12hp/9ft-lbs torque gain + the nice sound. An axle back for $500 maybe gets 1-2hp from what I've read on these forums, so its mainly sound. When you look at it, seems like you get much better performance per dollar going Cat-Back, if indeed you can gain 10hp/7-8TQ. Question is, is this true? Don't believe that reputable companies like ARK would exaggerate, but I'd rather see dyno numbers or get confirmation from experienced members saying that Cat-backs do deliver such gains.

Now, if there truly is an axle-back that can get us 5-6hp, then its basically the same hp per dollar as Cat-back, but much cheaper, and great starting point.

@Qtro ---I'm afraid so my friend. Called local dealer and they said it's an axle-back system, and confirmed its Borla made. Funny thing is that they said to actually buy them from e-bay or somewhere else, and then bring them in for install with them, lol

yeah ur better off buying ur parts in pieces and have the local muffler shop fill in the rest especialy for a catback.. i would go catback if you want performance numbers.. axle back is purely for sound no performance gains.

if you buy the whole setup online its gona cost you to ship and worst of all, install it.
but when you buy online, ther usualy Mandrall bent which is better air flow.

i did my entire exhaust .. cat delete and whole new catback (larger pipes, xpipe resonator, mufflers and tips) all for less than 500 including the parts and labor

Axel back does offer a performance increase. Just not necessarily that of a cat back system. Chopping 35 lbs off the back of the car and putting some mufflers on that actually flow is certainly an improvement.

Gotta find a way to eventually replace and upgrade the stock cats and mufflers, which are typically the most the most restrictive on exhaust.

Axle backs are great start for sure, but according to these forums only give you 2-3 hp/tq gains at most, and is more of sound upgrade.

MRTv2 axle-back works out to $550 for /3 hp gain = $183 per hp gained, approx.

Solo Mach-X-LFX cat back $900 / 10 hp = $90 per hp gained, approx.

Seems like cat back provides the better performance and value, but deff more expensive upfront. That's why some are of the opinion to just save a bit longer, wait, and just go w/ cat-back, cause in the end, most ppl end up upgrading to cat back anyways.

Don't have $1000 right now to dish on new cat-back, so will have to wait a couple moths. In this Florida heat and humidity, it bothers me that my 1LT is not getting the best breathing because of inferior grade OEM exhaust.

Is 7 more HP (theoretically) going to be noticeable enough to justify spending almost twice as much on the exhaust?

there is honestly no performance in a cat back alone. is 5-10HP really that great? is your car going to get FASTER? no really.

when talking about axle back and cat backs. its not about what gives more HP, because really they dont give a lot anyways. its about what sounds better. cat backs usually sound better than just a axle back (muffler).

Unfortunately, no its not enough to notice. Its all about what system and what sound it is that you want.

I agree. I meant my question as a sort of rhetorical question for the OP to make him realize he is nitpicking the wrong things when it comes to an exhaust.

Ah, ok. This is what i hate about forums, you cant really tell from plain text the context of the posts sometimes.

Unfortunately havent seen dyno numbers, except those claimed by manufacturers. ARK claims their dyno tests show cat-back 12hp gains, Flowmasters AT say 15hp, etc. Plus they make better sound than just mufflers, apparently. How reliable are these manufacturer's claims? If they're reliable, then are the 8-10 hp gains + better sound than only mufflers, worth the $1000?? If they're less than that, then deff not worth the $1000, imo.

I'm not going to say that removing the stock mufflers is a bad idea, however, everyone seems to overlook that they do help smooth airflow under the car and are part of the aero dynamics in connection with the rear diffuser.

Discuss. If you want to, that is.

They may help round off the aerodynamics in the rear of the car but that doesn't mean those two huge trash cans don't look absolutely awful from behind. I'll take a minor hit in underside aeros vs those atrocious steel boxes.

Not to mention the weight that you will dump getting rid of them.
