On the header back are 2.5 chambers. Can I just delete the cat with delete pips and use my factory h pipe? Help me save money instead of buying the hole system?

 

Another question? If I go with a o/r x pipe and I have a tuner to turn off the 02 sensor. It will put to much fuel with the air an cause the spark plugs to foul. Does this happen a lot?

 

1: don't screw with your stock h pipe, they are very affordable aftermarket from jegs for like $160. 2: order a tune if you have a tuner.

 

I have pypes lt headers, off road hpipe and pypes muffler deletes as far as exhaust goes, sounds awsome, loud as hell.

 

Never had any problems with spark plugs to

Foul, I've ran a 89 performance and now a 93 race for approx 6 months and no prob

 

Right after installing my headers I just got rid of the cats and got the tune to disactivate the rear o2 sensor and welded a connector on it so I could use my stock h-pipe with the headers.

Go with an X-pipe if your buyin aftermarket
