O2 Sensor H-Pipe Question

[bmxelvs]

Thank You very much for the input! A lot of really good information there, I think I will go with the XCalibrator as I have no need for different tunes at this time... The throttle body/plenum was already on my list, how hard of an install is it? Does it just bolt on or do I have to mess with the tps at all?

Also my check engine light still has NOT kicked on and I have put like 500+ miles on the car already with no cats which I think is pretty strange. Maybe it has something to do with the ceramic coated long tubes?

Lastly since I pulled my cats the mufflers I have on the car dont really sound that great. I have Raven's on the car right now. Anyone have any ideas on what would sound the loudest without sacrificing too much sound quality with my exhaust set up e.g. long tubes with 2 1/2" H-Pipe?

Once again thank you for the reply!
