Default GXP muffler dimensions?

I was wondering what the dimensions are of the gxp mufflers since I want to order some Spintech mufflers also what side is the inlet and outlet side on. If you've never heard these mufflers check them out.

if you are keeping stock on there, its 2-1/4" in and out. I believe you have Dual exits, so you would have to keep that in mind.

I went to the link you provided, but couldn't find any forums specific to FWD cars. Unless, the "NexGenMuscleCars" members (or founders) don't consider them to be true muscle cars. Personally, I think that notion is BS. The Impala SS, Pontiac GXP, and Buick LaX Super may be front drivers, but they can certainly hold their heads up high. In fact their 0-60 and 1/4 mile times could beat most of the '60s era RWD muscle cars, including my '66 Chevy Nova SS. However, the modern day RWD muscle cars, well that's a different story.

No not really a diffrent story mcss and impala easily smokes stock mustangs from
when they where born to 2008. They beat the chargers except for the srt
Those are the only 2 i think that are in the genre of the monte and impala.

When i purchased my monte carlo i had a choice between Charger R/T , Magnum , New mustangs , monte carlo and i picked the one with the fastest times. As for stock LS1 Trans-ams and camaro's we will get smoked but defiently hang in there till the very end and not by much most trans am WS6 ran stock 13.3 times plenty of montes here have made it into the 13.6 with little modifications.

I was just under my car today changing my oil (finally some nice weather out here in IL) I saw that the inlet on the mufflers is offset not the center as said eariler in the post.
