exhaust question

[holden_calais_VT_1999]

hay all can u use ur y part from ur standard cat and headers for your new exhaust extractors to high flow cat

Yes you can. The outlet of the extractors is 2", the Y pipe is 2", all you need to do is cut the standard cat out and weld in the hi flow. You will have to re use the flange from the rear of the standard cat for the rest of the exhaust to bolt up to it though.

just went to the exhaust shop they said they wont do it he wants $88 for the y joiner and what do u mean use the flange behind the standared cat

i already had a guy ask me about my exhaust and i told him he could have it so now we both have a problem

1 you didnt tell me i had to cut up my exhaust
2 you said nothing about the flange behind the cat

as far as what i was receving a hole exhaust system not bits and pices

Most extractors from VS through to VZ V6 don't have a Y pipe as they either come with flanges to weld onto the existing Y pipe or are a slip join like the the Wildcats. The system is exactly as I described it. You also asked if an exhaust shop can fit it, and they can. The only part you will need of the original system is the Y pipe. The cat back is designed to bolt onto the original cat, they are all like that. It's not hard to cut the flange off the front muffler and have it slip into the cat.
