timeless420, thanks for the compliment on the Brullen exhaust! I like it a lot too!
For performance information go here:
dyno results This is the dyno on my slightly modified SVT.
We had very similar results on the quiet system on a stock SVT.
Also, please note to all that asked, sound files have been added and can be downloaded from our website on our exhaust page. Sound quality is not the best but you get the gist of it. Only hearing it in person will do the system justice.
