Which cat-back has the best sound and power gains? GMMG, Corsa, or Borla?

Thanks!

And yes I've done a search, didn't help much.

 

i like the way GMMG and borla sound, the corsa clips ive heard, sounded to hi pitched

 

I absolutely hate Borla's sound. Out of those, I would go with GMMG.

 

no exhaust clip you ever hear over the internet can truly replicate what it sounds like in person. I say go with corsa because it's freakin bad *** in the gains you get. i don't know if the gmmg and borla give as much of a gain as the corsa claims to (14 rwhp), but who cares. corsa sounded pretty good to me. it's very clean sounding. good flow.

 

I loved my Borla. Also liked the fact it was adjustable Good quality piece.

 

to me the GMMG sounds the best out of those 3.

 

GMMG has a nostalgic muscle car sound while Corsa has more of an exotic import sound. Borla sound yucky to me My personal preference would be the GMMG

 

i have heard the corsa and my borla. my bolra has a really low rumble to it. at 1k rpm's i set off car alarms at 5krpm's i blow out windows..... well not really but i always get compliments on how much my car sounds like a harley.
the corsa was too quiet it was also on an ls1 corvette but it was still to quiet

 

BORLA

 

borla is nice...but sounds awful with headers or a cat

 

Cutout.......

 

exactly! borla is great on a stock car but start upgrading the rest of the exhaust and you will be sorry.

if you are really out to spend $700 on a catback then go with the GMMG. but if its pure noise you are after then go with a $30 cutout.

 

I'm looking for a nice cat-back that gives me the most power and sounds great. Power is more important, but I don't want one that will sound like **** when i get headers on there. I might consider a cut-out down the road, but for now I have no need for one. With GMMG, how much hp do they claim? I checked the site and don't remember seeing anything about that. Also, since it splits off further down, I don't need a y-pipe, right?

 

I have a Borla, no cat and headers. The cars sounds AWSOME!!! At WOT the car sounds like a nascar, very intimidating sound!!!!

 

I have the Borla and have heard the Corsa and the GMMG in person.I really didn't like the way either of the other two exhausts sounded.It's really a personal preference of what you are willing to deal with,s hlil less power with a much better sound or a bad sound with a hair more power.
