Thread: downpipe re: cat welding, help please!

  1. Default downpipe re: cat welding, help please!

    Hi there! I recently purchased a cpe downpipe catless, and was going to get a local exhaust shop to install a high flow cat and install aswell. But they wanted a stupid amount of money to install , also they could not guarantee it would not fit to the stock cbe after installing high flow cat. Therefore they would have to adjust the cbe to make the downpipe fit. So installed it myself to save 400-500 on install, my question is.. Where does the cat have to be positioned? Does it have to be in the downpipe? Or can I install a cat after the downpipe l, like inplace of the resonator? I'm Not driving atm cause it is catless...If not, I might have to buy another dp with the cat already installed and sell the catless cpe.(which I should have done in the first place.. Lesson learned) anyway any help would be GREATLY appreciated!
