Mac Headers w/ ORP and Magna flo exhaust. I am doing this set up now and have 1 question. I already have the Magna flo exhaust in. Does the Y-pipe fit right into the Magna flo exhaust? Somebody was telling me that I mgiht have to get one of those things that hooks on the end that goes like 2 1/2"-3". That make sense? Basicly the Y-pipe and Magna flo are different sized so they dont' fit without that thing in it. I can't remember what its called. Let me know if you can answer my question. Its on a 01 WS6 if that matters.

Re: Mac Headers w/ ORP and Magna flo exhaust. You shouldn't have to get anything, but let me explain myself first.
First off the collector is where the 2 pieces of the Y pipe come together, and the catback attaches into the collector. A lot of the older MAC Y pipes were too small at that place, and they would rattle around inside the aftermarket catbacks <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" /> The newer MAC Y's might fit better. If you put your ORP on and see it rattles inside the catback, there are 2 things you can do. I took mine to an exhaust shop and they took the Y off and spread one end of it open more with the pipe expander. Sealed it with a bead of some kind of orange goo and problem solved. The other option is getting an aftermarket collector and having it welded in place of the MAC collector. Or an exhaust shop could make an adaptor, flange/crimp a pipe that slips over your 3" catback and over the smaller MAC Y.
I'd put it together first and see if anything needed done. The cheapest will be to just take it to muffler shop and have the Y expanded, but it can only be spread so much...
