hey guy
i have an 05 sv6 done ss induction cai, custom intake piping, DKNE extractors, and a Mack 1 s/s twin 2 1/2 catback system. sounds tuff as nuts. i have tryed different exhaust setups, as i am a boilermaker by trade and have a car workshop and this setup i have found to work and sound the best ... but i will say this the extractors take out the deep note at high rpm gives it a real loud bark and when she drops a gear when you put the boot into it........ lets just say the guy in the car next to you with his window down will s%*t himself.
will post pic's up of the car ill even make a video and put it on u tube ill post the link asap.
