Exhaust Question

Ok so im going to put pacesetter LTs on with the TSP rumbler x true dual only problem is i have to have cats on to pass NYS inspection, they are going to be gutted but i can still pass inspection because of a friend, now my question is because i have a one cat car what am i going to have to do with the O2s and beause they are going to be gutted is there anything that i have to do?

Re: Exhaust Question

im judging you have a 93 correct? if so, i dont think the pacesetter long tubes will work, because they dont have the AIR tubes, so that will be bad there but the O2's should be fine because there is only 2 on those cars and they are both before the cat so it doesnt know somethings wrong... if im correct. just my understanding.

Re: Exhaust Question

Okay so what happens with not having the AIR tubes ..? (sorry probably a stupid question) I was going to get them from TSP and it says they have emission fittings

Re: Exhaust Question

im almost damn near positive they dont have the fittings for a 93 if they are pacesetter longtubes. they will prolly pop the hood, see the AIR tubes layin there and be like why arent those hooked up.lol. i was going to try to get around it with race longtubes and whatnot on my old 93 but i didnt actually do it and they dont do visual where i live only sniffer test. you should talk to someone who has done this with a 93 before. good luck.

Re: Exhaust Question

Oh and if they dont have the emission fittings and those tubes arent hooked up is that gonna be bad?(like for the car, i can always get around inspection)

You will probably fail emmissions because it helps heat up the cats so they become more efficient.
