Thread: SLP Powerflo Catback/zzp 3" downpipe

The glasspack I added quieted it down quite a bit, yes.

Before the glasspack it was loud all the time, with the glasspack it was only loud under throttle like leaving a stop light and going up hills.

I'd be willing to pick up when you get to crack head prices. Any intrest in a complete standalone nitrious setup with progressive control / timing retarder fuel and nitrious solenoids + purge valve? I've had it laying around for years for my LS1 and I'm sure it could work with anything.

Then standalone goes for $800
