new exhaust

[cormac]

Lads I just fitted a vintage speed S/S exhaust onto a mates bug, I took off a turbo muffler it's a 1915cc motor and was running perfectly, now it won't pull in 4th it bogs down do ye reckon it needs 're jetting for the new exhaust?

Might want to post this in the performance section. Might have better luck since you specifically stated a type of exhaust and engine size that is custom. Best of luck and hope you find an answer.

In my opinion the Vintage speed exhaust is a nice looking piece, but depending on what one you put on is not a performance exhaust. I put one on my 73 Ghia with a 1915 engine and I could notice a power loss immediately. I also could not get it to seal around all the flanges. The result was backfiring on deceleration. I replaced gaskets twice with no improvement. I put my Bugpak header system back on and the car runs much better. Just my two cents worth.
