How loud are these when you are out on the highway. I really dont want a full race car sound when going down the interstate although i dont really drive the car much. Maybe after I do the cam and heads it would be worth it.

I got the GMMG and I love it, best sound out of any exhaust I've ever heard.

Not that loud I dont think. I love the sound of it when I cruise!

well damnit, i guess im +1 for custom flowmaster exhaust (not cat-back) but thats my two cents. gmmg sounds great though

well I'm going to say it sounds better, just because the LT1 always sounds better imo

We could have put the Borla on the black Formula before you sold it, I could have given you some money, we both could have been happy. See what happens when comunication is poor?

The plan was to get the GMMG off it and swap it for the Magnaflow that was on my WS6 but 2 days after I put it out for sale it sold and I hadnt gotten the WS6 yet which sucked cause I figured my Formy woulda taken atleast a couple weeks or more to sell. I'll prob get GMMG again but if u do get rid of the Borla lemme know.
