Which brand/model mufflers use noise cancelling 'chambers' only
(i.e. do not contain any wadding/padding/fiber/steel-wool material)...?

 

I have a LM and personally think it's fantastic, but it certainly is loud, very deep and no rasp (don't believe what these non owners say about them. Provided you're running cats, which you will be in CA it will sound great)

Also it's stainless steel and looks good. LM2 is a tad quieter.

-Hooker
-TSP Rumbler

Are some other good ones, but not stainless steel.

Stay clear of the Flowmaster as it doesn't flow very well and will ultimatley hinder performance.

-GMMG
-Stainless Works Chambered

These are top dollar systems but are very well made and sound awesome.

Borla is popular, but IMO it's over priced, ugly and doesn't sound great. Plus I don't 'how' it works either. And that adjustable idea is just for people who have too much time on their hands. You'd be better off just getting a Hooker or SLP Dual/Dual (both pretty quiet) and a QTP electronic cut-out, it will do the same thing but cheaper and you can alter the sound from inside the car at a flick of a switch.

There are loads of other setups, none are particulary bad it's just more to personalising it to what you want.

IMO the SLP LM is 90% GMMG at nearly half the price. It makes the car sound like a muscle car, however if it's you DD (Daily Driver) then I can see it may annoy some people.

There are dual setups also, some claim these to be the ultimate. This is total bull from people who know no better. Ultimatley on the correct setup when you're well over 550rwhp then duals have the ability to outperform a Y pipe setup (provided you use 3" duals). But for most bolt on, cammed, head & cam or mild blower applications a Y pipe will work fine, even in 3".

If youwant duals there are very few kits, TSP make one with an X pipe but it hangs a little low and dumps before the axle which means it will be louder than any of the catbacks (LM included). It also means you can't run a body mounted torque arm. Custom duals are good, but can be expensive and require research to make the best of a custom install.

Check out www.ls1sounds.com it will give you an idea of what they all sound like at least.

 

I have the TSP Rumbler, and live in Cali. Never had a problem with police, and I give them plenty of reasons to pull me over: exhaust, tint, no front plate.

To me, the Rumbler sounds like a "cleaner" Loudmouth, and is cheap to boot.

 

If money isn't a big issue I would without doubt go for GMMG not only for the best sound ever but for the construction and it being stainless and not to mention the look of it with optional tips.

 

do yurself a favor and just get loudmouth..its really loud. with cats it sounds really damn good. with longtubes, its loud and viciously loud. you will get alot of attention..no doubt. i was disappointed with gmmg..and besides loudmouth is also stainless i believe for half the price.

 

yeah had my car on a lift and say my Y pipe and i was like wow is it supposed to be flatten lol so yeah. So far i like the GMMG, heard SLP EXhaust Does good the magnaFlow has a awsome sound but would like to see some dyno number the webstie dont show lol but then again im not lokin fo a big number diff. i just want a mean sound. but looks like im be getting my lid first before my exhaust. I know this aint the Thread but what u guyz think of American Racing Wheels Thorq. Thrust 2's Lookin at getting a 17x9 front and a 17x11 rear i want to know are they lighter then say the ZR1's

 

ZR1's are a couple pounds lighter than TT2's and both look great.

 

Any day now my Stainless Works 3.5" catback will be arriving. It was a pretty good deal, I got it directly from them for $587, they're having a sale. I'll let y'all know how I like it once it arrives.

The Magnaflow is a good system and can be had for under $400 if you poke around.
