cat delete

[htcvick]

I have a banks dual exhaust and power pack installed and I want to take out my catalytic converter out and replace it with a straight piece of pipe. What can I expect for a performance change, mpg increase and egt changes

Lower EGTS and some say you lose a little low end if you have the factory exhaust not sure on your set-up. Not much change in performance or MPG's

I have a banks 4" exhaust system and to take out the cat I will have a short piece of 3 1/2 pipe to replace the cat

Ok, so delete the CAT and sell it. This will pay for your delete pipes and provide lots of beer money. The scrap yards around here are paying $75+ for old CAT's... They nailed a guy at walmart with a cordless Saz-all cutting them off cars in the parking lot.

I deleted it but have to hang on to it smog rules but i'm good for a couple of years. used the old exhaust pipe for the bridge piece so all in all just a couple of hours of time to do it. now ill have to see the results.

I just removed my cat with a stock size 3.5" pipe. Didn't notice any power change or MPG increase, just a lot of noise (which I don't really mind)

I plan on beating the guts out of mine, welding some flow straighteners back in and re-installing it.
