Well its all finally here! I just got the last pieces of my exhaust in today after many months of debate. However before they are installed I have a few questions. The system ius going to be as follows, 2.5" piping after the cats into a 2.5" in/out Magnaflow X-Pipe, then straight back to dual Magnaflow 14236 mufflers with Magnaflow 5" (2.5"-4") tips. Its going to look and sound sweet. But the question comes up with the flanges. The stock piping is 2.25" all around, what flange do I use when connecting up to the stock cats? Anything special or a certain part number I should knno about? Remember I am going from 2.25" to 2.5" right after the cats. Any suggestions on this and any of the other flanges would be greatly appreciated since the shop its getting done at does exhaust, but it is not a dedicated exhaust shop and I have to purchase the flanges. Thanks in advance.

 

the stock sc400 exhaust is 2in and 2.25 piping the 2.25 being on all the Y's. And the flanges can be bought at lextreme I believe.

 

Lextreme is no longer making them, although they advertise them... Go figured, I just asked him a few days ago.
