The Supersprint has a 70mm tail pipe, then the rest of the pipework is 63mm inner diameter. (dogmauls is 70mm inner)
The main difference between the zorst designs is that i have a flange, so i can fit the original CAT back if needed. The 70mm doesnt have this.
I can only assume (havent had car on rollers yet) that i will be pushing out simlar power to the 152 atw that dogmaul has got, although it has been sujested that i may get more tourque due to the smaller tube. Im not really that bothered, it feels much more eager to rev from 5k upwards, and the exhaust doesnt really clear its throat untill 4k.
Pictures to follow on a dry day. (summer then!!)
