Found my HP problem - ZR-1 Net Registry Forums

Went back to Twisted Pipes today. Mike was very pleasant and willing to accomodate me. They immedeately put my car on the lift and we took a look. Long story short they installed the Mflow resonator/xpipe, had to fabricate the head pipes to connect to headers and fabricate a connection to the corsa mufflers. I supplied the reducers, connectors and clamps. So now it's 3" all the way from the header collectors to the Corsa's. Stood there and watched the whole thing. It came out very nice. They only charged me 2 hours labor, it took 3.5 hrs with 2 guys working and me supervising.

Interestingly I noted that the Mflow resonator actually has an x-pipe inside it, in addition to the x-pipe fitted on the inlet side. Strange that they would set it up this way.

In driving the car afterwards, Surprisingly I noticed that it's now somewhat quieter. No resonance what so ever. I have to say I really like the combination of Mflow x-pipe/resonator and Corsa mufflers. Problem of course is you only get these Mflow and Corsa parts as part of full systems. Really can't say I felt any more power at this point.

Next comes the Dyno. We'll see if this change made any difference at all. Third times a charm, as they say.
