Adding a glasspack...

[mcvey]

Hi, I've got a 3" ZZP DP with the 2.5" exit flange and I was wondering what the in/out size I would need on a Thrush glasspack. The rest of the exhaust is stock and I'm going to cut out the resonator and replace it with the glasspack. Would I need a 2.25" or 2.5" in/out for the glasspack?

Not sure on the size but most set ups on GP's sound bad with glass packs put in place of the resonator.

x2! get a whisper resonator from zzp with some flo pro mufflers

a glasspack will give it a more throaty sound than a resonator will, but it will also fail quicker. a resonator is meant to keep the exhaust quiet. a glasspack is meant to add tone. just make sure if you do switch them out you find the longest one you can (24" or longer) fit.

Yeah I know. I've seen clips of some of the cars with the 28"~ glasspack and I went with one of those.
