test pipe or stick to stock cat. HFC, too expensive for very minimal gains

 

I have a high flow cat. Im going with a test pipe because of more gains and Im tired of the cel coming on cause of whatever reason due to the cat. You will need a o2 sensor. Its about 100 bucks. You will need to hang on to your old cat. Emissions now days just hook your car up to a computer and if it doesnt code its all good. But some places look to see if you have a cat. I recomend banging out your cat making it like a test pipe but at the same time looking like a cat on the outside...

 

If you live in Cali, don't do it. Anywhere else, sure, no problem. Cops seem to be a little strict in Socal, ie: pulling people over for ANY reason. Peace.
