4" magnaflow WOT pull.. video included.
 

was at a good friends house just the other day for shot guns and four wheelers and such. he lives out in the middle of nowhere, and has some great roads to run the S on. decided to get a shot of my exhaust, so if you go with a 4" single, this is very close to how its going to sound. WOT from 2nd-4th redline.

and the ST's are AMAZING on country roads, couldnt be happier with how they perform.

exhaust setup is-- 3" ASP dp's merging into a single 4" with 2 magnaflow resonators.

let me know what you think!!

not bad...

i rather run it without resonators... just a magnaflow muffler

nice..run without the resonators...I just might change mine to 4" sounds sweet!
