or maybe the magna flow catback? Opinions please!

ls1sounds.com

it comes down to personal preference and money

borla or slp loudmouth for sure

The GMMG is the single most expensive exhaust while borla is not too far behind. For the price of a SLP Loudmouth around 500 w/installation it is perfect. Gained .3 on the 1/4 mile.

If money is not a concern, then GMMG is the best sounding exhaust period..............

I 2nd that!

Just installed the GMMG and wow it sounds good. My buddy has the magnaflow. The magnaflow has a really nice tone but its quiet. The GMMG just sounds deep and has a great tone. Sort of loud but not obnoxious, best sounding catback that I've heard.

I would go with GMMG if I had the money, otherwise I rather get either a magnaflow of loudmouth over a borla and save some $.

for the money...magnaflow, but the GMMG sounds bad *** with LT's and ORY.....

Gmmg or true duls only

GMMG is the best. Borla and Magnaflow are tied for me, but Borla looks a little better. Then Magnaflow is kinda better than Borla and GMMG because its cheaper.

GMMG for your setup as is.

Magnaflow if you go with LT's later on.

Not always, Borla from Speed Inc. is 749.99 for the Quad-Tip exhaust where gmmg is 700 shipped... 850 if you tack on the oval tips.

Oh and GMMG all the way

Some people are haters, but that's cause they can't afford it.

If you want to spend all that money on just a catback, Corsa is exotic sounding and has the best looking tips of any catback by far.

I love my GMMG.

I had not heard a Borla or GMMG in person when I made my purchase, but I went with the groove and got a GMMG. It truly is AWESOME. With stock cats and manifolds, this thing is DEEP and loud. It's such a step up from stock, I can't wait to see what some longtubes do. Here is a vid of my car after intial install.

I'm not going to knock any other brand cause I haven't heard them in PERSON, but you can't go wrong if you pick up a GMMG, IMO.

ive owned SLP loudmouth, magnaflow, corsa and heard/seen borla here's my experiences
- borla = average sound ; gross tips ; good build quilty but overpriced
- corsa = exotic high pitched sound ; exceptional tips ; avg build quality pricy; low resonance
- magna flow = nice WOT ; tips could be longer ; avg build quality ; low price ; low resonance
- SLP loudmouth = awesome sound WOT ; o.k. tips ; avg build quality ; low price ; very high resonance (new loudmouth II lower resonance)

Word on the boards GMMG and Tru duals are godlike but GMMG is expensive

GMMG..enough said!!..

Another vote for Corsa. And yes, I'm biased.
