How much of a power difference is there between the GMPP touring and sport cat-backs? I like the touring sound better but don't want a big disadvantage in power.

think the power differences would be very minimal seeing how the gains from the exhaust are nothing amazing.

stupid question maybe, but if it's a lease can putting the GM exhaust on the car void anything lease and warranty wise?

p7x

can't void warrenty because it's GM basically.

With a lease it's a lil trickier. When I told GM I was going to mod my car (lease) they said im not allowed, than I asked them if putting winter wheels and tires on is ok and they said yes. And than I had them, since they said I was allowed to but something on the car not GM (winters) they indirectly agreed to it. The manager i spoke with was not happy but every dealer i have talked to cept one has backed me on it.

It comes down to having a good dealer i find.

That's kinda of lame because once the car is leased to you, the dealer is out of the picture. GMAC is the registered owner, you're the leasee for the term of the contract. If you go ahead and screw the car up, you're the one who has to deal with it at the end of the term. You know what your options are (buy it, fix it the way it was and give it back, etc), so how does the dealer have anything to do with it? I think they're just trying to powertrip. My car is leased, I am buying it out at the end because I can't afford to roll over another lease, and I'm going to town on this bitch

GMAC does own the car, when I said GM I meant GMAC. When I told GM about it they gave me the number of the GMAC rep. Either way my options at the end are return the car to stock and trade it in or buy it out.

The dealer aspect comes into effect concerning warrenty issues. If there is something wrong with the car u don't ask GMAC about it you ask the dealer.

the only thing it will void would be the stock exhaust.... which wont be on there anyways
only problem you would have would be if your GMPP exhaust caused a huge problem in your car

Oh I'm sorry, I was confused. I thought it was the dealership saying "No you can't do that". ****, I don't even want to know that there are numbers for calling up GMAC to ask permission for stuff
