Why??

[adrianc]

Recently changed the header pipe on the 225drs and I have noticed a bit of a change in the performance, it is a bit quicker than before.
I changed from an oem to an oem pipe. old one broke off at the weld joint next the engine.

Any reasons why there is a change in performance.

is is dented? bad weld? bent? or anything blocking the flow? extremely high carbon build up ?
