TTI Exhaust on Early A's

DJVCUDA said

Rick - I had 71 - 340 manifolds ( i didnt forget !!) and te car went 13.3 @ 102

I went to a shorty spitfire and it went to a 12.80 @ 108 - no other changes.

Online calcs make that an easy 30 hp difference.

I'm curious to see if there is a difference from the short tube to the long tube.

Hope for your sake it's even more.....the time slip is always the best dyno....if it's only one change at a time...!!!!!!

I would be interested in hearing about any vibration or unwanted noise due to some of the install pics ^^^^^^^ I'm seeing showing tubes rubbing frame, torsion bars etc. ???????
