I had a quick question about the borla exhaust system. If i wanted to install a borla exhaust would the exhaust run from headers back so do i need my stock cats? or does the borla system comes with the pipes that runs from the headers into the cats that borla gives you.

 

you dont believe me do you....lol

 

Borla exhaust dont run from headers back. They run from the cats back. You dont touch your cats at all. Start at Y-pipe and go from there.

 

lol i believe u i guess i am just an idiot haha

 

not at all bro.....you just have to learn sometime.....

just like we all did

 

correct

sounds better if you replace the OEM cats with some test pipes though

 

Test pipes hurt the environment...HFCs ftw!

 

I see that you are from california, so you have no choice. Before I saw that, I was going to suggest trading in your car for a prius lol

 

i am trying to get rid of my full TD borla exhaust system and put on a greddy single or td exist tic exhaust. what would i need if i want to change out the borla for geddy.
