Pypes race flow on three cars (3" on two and 3.5 on the other) and I'll put them on the next project as well. Quite-ish when cruising and mean when the foot goes down.

I am installing the Pypes SS Syetem with Street Pro Muffler, they system includer X pipe and cutoit provisions. Pretty easy to install, except 3" tailpipes over rear axle. They hit the rear coilovers. Will need to do some fabrication to get them to stop hitting.
Question: anyone running the Pypes cutouts? Are they dependable over the long haul.

Thats a nice setup.

I used the Flowmaster 50s with full tailpipes on my '67 LS1 build. They are extremely docile at idle but they sound really throaty at cruise but not obnoxiously loud, with absolutely zero drone. They sounded somewhere between that classic flowmaster tone & a turbo muffler. I'm not a fan of Magnaflow's sound at all...way too "crackle & pop" for my tastes.
