ermm... big pipe little hole lol.
We did mine first as the test, it fouled on everything. The lambda bosses are almost pointing down, which is bad for sensor life. Add to that my pipe had a 3rd boss for the wideband, welded opposite the primary. This means that the wb boss is now pointing straight up, so no wb for now.
As westec ****ed up my supersprint pipe, we had to spend some time getting the pipe to fit properly. Finally got it sorted though and its solid as a rock.
Started phil's expecting it too be easy. No chance, lambdas are seized in the milltek pipe. We fitted the decat pipe without the o2's and he drove it home. Not such a big deal since it aint used daily, and the garage is litteraly 1/2mile from his place. Goto sort it this week/next weekend.
Mine sounds really nice, didnt sound any different on idle, but under load its awesome. Really pleased with the sound but narked with the fitting. Spool up is awesome too.
