My setup is in my signature. Basically i have the OBX long tubes with ORY into a single 3" exhaust dumped before the axle. First setup i had a 3" Summit glass pack mounted...wasn't happy with this setup so i recently ordered a 3" Moroso spiral flow race muffler and have been running this in place of the glass pack for about a week now. It did quiet it down some but by the seat of the pants i have lost some power. I just ordered a round straight through magnaflow to run instead along with a cutout for the track.

Glasspack: To Loud! And not the best for power been proven time and time again.

Moroso: Great Tone...but not meant for a single exhaust IMO.

Hope my experience helps out when picking a exhaust. IMO the moroso's might be great in a dual exhaust setup but certainly not in a single system.
