Actually to me it suggests Pettit was buying the downpipe from the same source and reselling it with a larger markup.

Perhaps recently but my Pettit DP from a few years ago was different. It wasn't polished, needed an allen bolt to fit in the rear lower stud and had no problems lining up bolt holes. If I remember, the O2 sensor was in a little bit different location also.

If the boost goes up, will the F/A be affected? I don't want a lean running engine. I also recently install a larger IC with better flow, would this too allow an increase in indicated boost? (I have a boost gauge but I'm not yet sure if it's working correctly, I still have to drive on it).

no it wont. rhd's have to have a kink in the dp. the hks pipe will fit a rhd car, but most others will not.

the reason it will not fit is because the steering column gets in the way. thats why there is a small "dent" in the dp for rhd cars.

thanks, dude
