Who's running 14's with Dynomax cat-back?
If you run the 1/4 mile in less than 15.0 seconds and are using the Dynomax/Walker SuperTurbo cat back please tell me what times you ran. I would also like to know what type of induction system you were using, so I can try to determine the limitations of this exhaust system. Thanks

My friend Joe (SLP IROC-Z) ran a 13.9 @ 97mph with his Dynomax catback. This spring he started running 100mph traps but had no traction off the start.
He has a stock TPI setup with a ported plenum.

My best 1/4 so far with the IROC is a 14.3@97, and I'm still using the 2.5" dynomax Super Turbo catback.
I even have a sound clip.

The car should be much faster, but that's a whole 'nuther story.

cool, thanks for the sound clip. The car this will be going on is a 305 with about 220hp, I think both of you have 350's. I read in another post that "a" super turbo free flowed up to 175hp, but I know it was not the part number used for our cars, so it might have been smaller or whatever. Anybody else have times?

I had the 2¾" system on my Camaro with an LG4 and had hit 14.494 and 98.69 with it.
