I have the Pypes 2.5" x system on my 69 bird.

From the headers to the mufflers, the fit is excellent. The fit of the over-axle pipes leaves a bit to be desired.

I originally ordered my setup with the violator mufflers. It was cool at first but I grew really tired of the sound. It was blatty and always screaming at you. The RacePro's are supposed to be fairly tame until you step on them, then they get about as loud as the violators. Both of these mufflers will have a decently high pitched sound to them. The StreetPro's don't flow as well as the RacePro or the Violator, but will sound more like a traditional turbo muffler.

Ultimately I removed my violator mufflers in favor of a magnaflow muffler it it's place. They're virtually the same dimensions, so I was able to make that work easily. The magnaflow mufflers have a much smoother and rounder tone. Still probably not for everyone, but much more to my liking.

If you're after that classic muscle car sound, I'd stay away from the Pypes or Magnaflow mufflers in favor of a dynomax or flowmaster kit. Those will give you that more classic sound. The dynomax kits should flow around the same as the pypes kit with the streetpro mufflers.
