Mark, I put 3 inch ultraflos on my Satellite, with 3 inch pipes and dumps at the axle it was too loud, sounded great, but I couldn't hear the engine and didn't like that. I bought some Hush Thrush Turbos, which were like 40 each, for a short term fix. They neck down to 2.5 inside. The more expensive Dynomax Super Turbos don't, but to be honest the car will be uncorked at the track and I wanted those Hush Thrush stickers. The car is still loud but much quieter at idle and low RPM. You can hear it coming though.

My girlfriend says theres still nothing "Hush" about it.

Now I need to pin those needles, got to feel that heat
