TTI Exhaust on Early A's

Congrats on getting the install complete....Will be interesting to see your dyno results since the only comparison I've seen only showed a peak 20hp gain over the hipo manifolds...??????

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.
