Wha??? Come on now. Borla, GMMG and SLP certainly have more.

So why did you add the powerstick to the GMMG?? Too loud? A little too much rasp with the cam?

If the Magnaflow is too quiet than get a cut out. You get the best of both worlds and dont have to listen to a ***** out annoying exhaust all the time.

The GMMG exhaust may be a little raspy without cats in the 2200 rpm range but it definitely does not pop. I would look into the SLP Powerflow conversion before you spend $800+ on another expensive exhaust.

I've gotta call bs on that one, but to each his own..

imo Flowmaster, borla, and SLP loudmouth have the most rasp.


on another note, OP I have magnaflow on my car, it is damn quiet until about 4k rpm then it opens up, its too quiet for my taste so I also have a cutout which turns it into a Beast

I tried ORY with my GMMG and it was obnoxiously loud and raspy. Ended up adding cats and a powerpack to calm it down.

A buddy has Magnaflow and ORY and it sounds great. Plenty loud and no rasp.

You've got to be kidding. My 2001 Z/28 with Macs, and Borla had terrible rasp until I did the !ball connector mod on the Macs and had a custom y-pipe made with a Flowmaster merge.

My current car, 2002 Z/28 with ARH's with an ory-pipe and Magnaflow quad tip has zero rasp. I'm sure the ARH merge collectors and y - pipe are part of the reason of no rasp. I think the Magnaflow is the best CB out there, because it's relatively quiet at cruise, and has a great sound when you get on it.

In summary the CB is not the only reason a car will have rasp. You need to look at your complete exhaust system. In my opinion the 2 raspiest exhaust are LM1, and GMMG with headers and off road y-pipe.

the ta in sig has stock manifolds, an ory, and weld in flowmaster 80 series...it's raspy as hell from 1200-1600 and 2200-3000. it is annoying. the car sounded good with the ory and 99 manifolds, but as soon as i put the 01 manifolds on it...dayum. i am a firm believer now that the new(er) manifolds flow better. the car definately got exponentially louder.

No questions...GMMG.

Yes it's raspy, but at just the right times. It sounds amazing though...

Something is broke with his Magnaflow then.

Seriously, Ive heard more LS cars with a Magnaflow than I can count and NONE of them have had any rasp.

However, rasp is subjective. Its different to everybody.

Also, you will never hear rasp at WOT. Get some in car videos of around 2000-2300 and I bet youll hear it.

i have both magnaflow and gmmg sitting in my garage and magnaflow is going on my car. the gmmg is pretty loud and there is more rasp with it. i don't mind the rasp too much but i wanted to tone the car down a bit. if i want it louder at times i will go with a cut out too. on a stock car i loved the gmmg sound. after a cam, heads, stall, etc. it is too loud for my tastes.
