how much louder will the pacesetter headers make my exhaust right now i got stock manifolds an y pipe no cat then to the magnaflow stainless steel exhaust all 3" pipes

 

They are a little louder, but not 10x louder or anything crazy. THey also give the car a really nice tone. Instead of sounding like a wet fart at idle as it does with manifolds, it will sound like a performance car.

Above 4000rpm, they car will still sound like utter crap, but below that, it will sound very nice. I had a set for over 3 years on my 3.8camaro.
