i recently posted a questoin about removing the cat. many of you said that you would just gut the cat. is there any loss of power from the air expanding once it reaches the cat and then having to go back down to exit? are non turbo cats the same size as the turbo cat? i was thinking about going to a local junk yard and pulling a cat off there and gutting that one so i can keep the one i have for future use(if i need it). i think this would be best or should i have a weld shop fabricate one for me? thanks for any input regarding this topic.
