Test Pipe help
I recently picked up a used Invidia TP mainly because the deal was too good to pass on. It is a 70mm tp, and I'm running a HKS hipower dual which I believe is 60mm. the obvious solution would be to sell the 70mm and buy a 60mm tp, but I feel like I can make this one work.
The first concern is with it being a 70mm tp, will it still directly mate to the stock headers which I beleive are 56mm?
The second concern is the step back down from 70mm-60mm. It appears as though the TP flares out at the end to a larger diameter. Is it possible to just bolt it on and go with the HKS or should I hack it up and add a 70-60 reducer? I'm tempted to just do what I'm good at and frankenstein a custom straight exhaust like I did on my STi.
Any input is appreciated.

that's good to know. I'll probably just try it that way for a while then. It doesn't have the CEL fix either, two spark plug anti foulers should do the trick right?

it will bolt up 100%. but you might or might not get the benefits of a test pipe since its not the same size piping.

I got the pipe installed last night. I think I need to tighten the o2 sensor better because I have a buzz/rattle rolling off in first. Otherwise everything is good. No CEL, no rasp, no drone, plenty of exhaust smell. I can live with the sound I suppose. Butt dyno says it added 3000hp at least.
