I have an O.S .18TZ. I am currently using the HPI Tuned aluminum pipe as O.S doesn't sell a pipe for the TZ anymore. I have a THS aluminum tuned pipe lying around from my 18SS engine (MT2) and I was wondering if I just sealed this properly that it would work better then the HPI Tuned pipe? The THS is better tuned then the HPI, they are both for the 18SS engine but I am using the HPI one on the TZ.

Would this cause any problems? The pipe is a spring connection one and the header is suction mainafold but the connection looks to be just as sealed if I was applying a Suction-to-Suction.

What do you guys think?
