Thread: Dumps or Tail Pipes?

My 2 cents.
I was going to use electric dumps. I even bought a brand new set. Then I did a bunch more research. I could not find a single reference showing any real performance gain to be had by using dumps/coutouts as opposed to good tail pipes. The exhaust gasses have cooled so much by the time they exit the tail pipes that even the diameter of the pipe is far less critical. I decided to avoid the mess and issues, and am glad I did.
If it's purely a track car, then dumps are fine. If it's not, then I think it is a little "bush league" but that's just my opinion.
Tailpipes will make a very large difference in sound -both in terms of volume and overall sound.'66 GTO Vert Project "Red Ink", 462ci of stroked pontiac power, TKO600, SC&C Stg II+, Tubular lowers, Currectrac Rear suspension, Moser 12bolt w/Truetrack, Wilwood Master and discs all around, too much fun for words...

On my car, I have the mufflers right on the headers leading into an X-pipe, then dumps out. Sounds awesome. It was going to be temporary at first, but it grew on me real quick.
