If you decide to go with test pipes and you're goal is just decibels then I would go with the cheapest ones you can find. . .
Hey drkay will you post a sound clip up plz Sir?

You lose any hp from the lack of back pressure? I'm interested in doing this to my g37, but want some stats.

No, but don't do it. If you want a loud car, get a V8 and delete the mufflers so you can be like every other GT/Coyote Mustang.

One of my neighbors has a mustang GT 4.6 with deleted mufflers that things sounds annoying and cheap! I couldn't see myself deleting the mufflers on my G I rather have a Axleback
