Hey,
If i were to buy a borla cat back exuast what else would i have to buy to make it a true turbo back exuast. Also i wanna make this so i can pass emmisions so i would have to leave one cat right???
Thanks for the help
Matt

 

Thanks for the info.
But don't you also need the up pipe and mide pipe also.
I think i also read that if you remove all of your cats and put a hi flow cat converter in there you will pass inspection. Im looking for the best flowing exuast but i gotta stay legal.
Thanks
Matt

 

the dp replaces the mid pipe and the front pipe. an uppipe would be useful but it isnt part of a turboback exhaust
