I was gonna order GMMG cat back. I met this guy and he's selling me one, but does it matter what year it is...its for an LS1, but notice when you order it you have to say what year LS1 you got..Would it still work??

The earlier years had a slightly different y-pipe than the later years, but all in all it won't make much of a difference. If there is any problem it would be where the y-pipe connects to the cat back (I-pipe). Very easy to adapt if necessary.

All hangers are the same all LS1 GMMG's look identical no difference for any years in particular.

How much you get it for? It IS the BEST sounding Catback out there HANDS DOWN.

He sold it to me brand new never installed for $600. I picked it up in sunnyvale. His SS was cleaaaannnnn

Do any of you guys know how much it would be to get it installed by a proffessional? I wanted a real clean job...I just wanna bold it on. I just want them to cut the pipe for me

Usually its just an hours labor. It only took the guy who installed mine 30 minutes to do.

The GMMG is the best sounding exhaust IMO. I wished I had $700 to buy one. $600 was a great deal... Some day.

Hmmm i dont know about that, i use to have the adjustable borla and it really kicked ***!! I like the GMMG too, 2nd runner up, but i find it rasps more then the Borla.

Just install it yourself. All you need is a jack and some jack stands. I will never give a cat back that much power, i will sound better, but just changing exhaust, good luck.

It sounds 100 x's better with LT's, The initial start of tends to be louder then after you get into 2nd gear, maybe thats because it may deafen(?) you somewhat Haha! No drone, nice tone at cruising. It was a HUGE upgrade from my loudmouth! I LOVE IT!

It is also much louder outside then it sounds in the car, it is MUCH louder. if you ever get thechance to hear one in person have them rev it and take it for a quick sprint maybe a block or so taking off where you are. It is Absolutely AMAZING

I was reallly surprised how loud it was outside the car. The first time i heard it was when i had my car dynoed. Oh my god was it loud. Not bad at all in the car.
Youll love it with lt's. sounds amazing

I think its just loud enough to appreciate it while driving around in the car, but I haven't had anyone do any drivebys for me yet so I couldn't comment how loud it is outside....except that you can definitely hear it a few houses down during idle

I didn't think it was loud until I got my converter ... now it is almost over the top for a daily driver. But the tonal quality is awesome - WOT is vicious.
