I bought one of those ebay ceramic coated exhaust headers for my 99 dohc r/t. It was supposed to be direct bolt on, but of coarse, no. It ends up too long, so I'm going to have to somehow cut the pipe before my cat converter. I want to just remove the cat converter but then id have the problems with the down stream o2 sensor screwing with my computer. Would the sensor cause that much trouble or would i only get a light on my dash come on. I've herd of that you can get simulators for the o2 sensor but haven't found any yet. As for the exhaust, iv read that the r/t already comes with a good exhaust, but I'm looking for something louder. Do the fart can mufflers perform well or would it be just the same with the sound.

Also, i purchased a Indy header and was wondering if I'll get a considerate amount of power from it. I have it bored out to 60mm matching my throttle body.

 

for the fart can...just get a coffee can lol... no performance just loud and annoying and howellauto. used to have the o2 eliminators but i cant seem to find them anymore... hmmm

 

you can take out the cat and not have any problems with the car running bad......when i took mine out in the past the car ran alot better.....

so you bought an ebay header and an indy header?????
i assume you mean indy intake....i head the indy intakes werent worth the money

 

The Dynomax muffler looks stock and has a deep sound to it. The Indy intake, from what I have heard, is a PITA to install.

 

yea the indy is a intake not a header my bad...i got the indy intake and the 60mm throttle body for $420 so it was a bargain.. but if i remove the cat then only my computer light will come on then right? ... what do people usually use to make their CAI, would exhaust tubing work?

 

That it does i have it and that with the cold air it sounds like a ****ing champ. yeah it has the same stock muffler appearence but its actually bigger and sounds hell of a lot better. ill try to take a vid of how mine sounds

 

you will only have the engine light yes.......if you even get it...when i took out my cat the light never came on

exhaust tubing will work, or some big rubber hose

 

the check engine light has been on in my car anyways since i dont know when i just took the dash apart and took the bulb out that took about 10 min

 

i know there is a problem with my car when the light goes off....its on all the time and works fine, but when its off there is usually sumthing major thats wrong....

when i broke the timing belt on my first neon, the light went off
when i broke a rod and really messod up the motor on my old r/t, the light went off

 

the indy intake is kind of useless N/A, but with a turbo setup they seem to be worth it.
