Nah, not with the 2V. The 3V yes,- hell the factory doesn't tune them right, -from the get go unfortunately.

OK...status update.

After much debate, research, and some invaluable guidance from frog and brew, I've changed my exhaust plan to the following configuration...

Pacesetter LT's > hi flow cats (maggies) > Y pipe (2.5" from cats to Y then 3" from Y to muffler) > sido (3" in/dual 2.5" out) maggie muffler (undecided which one) > dual 2.5" pipes out the rear.

I figure with me not having a tuner/custom tune yet, this is the best way to go for best all around driveability and compromise on exhaust note.

Thoughts, inputs??

Sounds to me like frog and brew gave you all you needed to know.

Oh yea...have it narrowed down to one of these for the muffler, unless someone has another recommendation...

12198 > 5x8 oval sido, 14" long
12288 > 5x8 oval sido, 18" long

Honorable mentions...

12588 > 5x11 oval sido, but it's 22" long!
12763 > 7" dia round sido, but it's 24" long!

My concern with a single muffler, I don't want to end up toooo quiet, so was staying away from anything much longer. I guess the 18" is a safer bet, and will probably still have a great sound.

Is there any reason to go with a SISO muffler instead of a SIDO and run a Y for dual pipes?? I'm thinking not.
