Taken from SLP website its the perfect tips and looks for me... will it fit?
\1

I don't see why it wouldn't...SLP is a great company....
You're just gonna unbolt your suitcase muffers, and basically replace them with a nice pipe and fancy tips.....

Just an FYI, they are loud.

yeah just hoping they do really hoping cause there awesome!

is that your camaro ss in your sig. cuz damn thats nice......as far as the exhaust goes, i believe the v6 exhaust is smaller tubing so you may need an exhaust shop to make a connector peice for you......

The V6 uses 2.25 inch piping. Really, if you want to, just buy mufflers, universal X pipe, then take it to your local Monro of local exhaust work shop. Generally, if you get a cool employee, they will willingly remove the resonators for ya to help give that deep roar.

But, back on track. The V6 uses 2.25 size piping, so nothing bigger will fit.
