Everything else is stock.

I was afraid of it being too loud before I put it onbut now I want even more.
The interior isn't loud at all for those that are worried about too much noise.

Yep, the Flows were my choice of muffs until I stumbled upon the IMCOs.

Nice car! I love the CS package. Decided against buying one b/c I will NEVER polish another wheel long as I live. Found my 08 with the chrome wheels. I want the side scoops though!;)

I had the flowmasters but i ditched them for my boomtubes. Best thing i ever did.

Get an o/r h pipe. That will really wake up those flows! (its really loud, though)

They sound good. Gotta love that muscular growl!
