As already stated, HP gains in the range of 8-12 (or whatever) are probably what you can expect. I didn't notice much of a difference in HP at all when I built my exhaust and the car was stock, however, the sound was GREAT . Keeping in mind that 8-12 HP in a 3500 lb car is like an extra passenger on the Titanic.

I am looking to do an exhaust this spring and using a straight through round in place of the resonator crossed my mind. I'm glad to see others did this and it works well. I want some more power from it but mostly looking for better sound without the dreaded drone. I drive it every day so I want it to sound good without being annoying.MikeGS said:I run an stainless SLP cat-back (Magnaflow muffler) along with a Magnaflow straight through round for a resonator. It sounds nice and mellow with a deep "small V8" tone and near zero drone on the road.
Generaly, a resonator will help kill drone and higher piched (raspy) noise and let the deeper tones through.
It all depends on what you want. I hope this helps.
