Any sound clips of new exhaust?? Looks pretty damn badass!

How is this progressing, digger ?

[Nutzy]

Yah man, post some dyno vids or something!

hit an unrelated "snag", will reveal more when i am able

thats amazing , great work! i was wondering how's the relability of the engine by stroking it to 3.1 since i don't know about this and in my country no one has done it because this factor that we don't know :p the life of the engine might be lower right? keep up the amazing work!

Its all stock parts except for pistons, the life of the engine isn'treally affected.

Wow, I wouldn't have expected x-pipe placement to make such a difference.

Correct collector length and termination is extremely important. Since an X-pipe creates an impedance change that terminates the collector, X-pipe placement determines collector length and as such can have a very significant impact.

had a few issues shall we say that have been keeping me busy. here are a couple happy snaps

Car looks great :up:

This whole thing has me wanting to do some major research before I build a better exhaust system for my car.

Love this thread.

I see your lambda sensor is very far from engine as It is on my car, does you have issues with sensor working propertly, or it works fine?

Won't bother it being that far. When we tune cars on the syno, the wide band is clipped to the tail pipe. I have noticed it causes the AFR reading to be about 300rpm off when making adjustments.

thanks guys. yeah mine is tuned with O2 up the tailpipes. i have two ports in the Merge and one is still free and the ohter for the WB. so may get them to tune with it as it is precat which is supposed to be better

I can't for the life of me find where to get the 45mm valves. Is there any way I could ask you to point me in the right direction to get a set of those?
