i just put shorty headers and a full exhaust system on my car with a spintech muffler and i must say that it is a badass muffler. it doesnt sound like a flowmaster and that is exactly what i was going for. something that doesnt sound like a damn flow and no one else around here has one

 

Yep, pretty unique sound to them I think. Happy with mine but the system needs to be redone for the 350. Been saying that for the last year so I dunno when it'll be done lol
