im about to oreder headers and was wondering if the pacesetter longtubes would be a good choice? also they say its a 2in outlet on the headers. am i gonna loose power running 3in all the way back? or should it be rduced to 2.5? also what about the 02 sensors? i have the sct tuner as well

 

If your running single 3 in you won't lose any power. I have pacesetter long tubes with the matching y pipe with a single 3in pipe running out and I didn't lose any low end power. As for o2 sensor you should be able to turn off the rear ones with the sct.

 

ok. ill probably run single. now what about the front 02?

 

You'll need to keep the front o2s, the headers are pre drilled and have bungs welded on already
