Downpipe compatibility with XTune Exhaust

[Dagda]

Hey like the title says, I bought an ebay Cat-back system a while back by Xtune. now I want to put on a cat-delete DP and I think i found the right one. however, the outlet of this downpipe is 3 inch, and the inlet is 2.75.

here's the link: http://cgi.ebay.com/ebaymotors/ws/e...STRK:MEWA:IT&viewitem=&item=120152558492&rd=1

or try: Ebay item ID #: 120152558492


so my questions are....will the 2.75 inlet match my stock/(possibly ported in the future) 02 housing? AND, since the outlet is 3 inch, what about the 2.5 or 2.75 neck down that those cat-backs do to fit on the stock cat? my idea was to take it to an exhaust shop, and have them modify the flange from the cat to the catback as a 3 inch, and then maybe its a direct bolt on from there? i dont know, please help soon!

All ebay downpipes I've seen neck down at the end to 2.75" where it connects to the catback piping. But most catbacks on ebay I've seenstart at 2.75", if yours is like that, it should be no problem.

As for the connection on the o2 housing, unless you have an EVOIII o2 housing, or some other type that angles the studs, you should be fine. If anything a slight filing of the holes on the downpipe flange MIGHT be necessary.

Everything is compatible if you have a torch, welder, and about 45 minutes to blow.

Just a tip, if you fit the pipes yourself and then take them to the exhaust shop for a bench weld you can save yourself about $40-50 from them not having to put your car on the lift and take your exhaust off.

did you see the auction though? it said 3 inch outlet. doesnt that mean where it connects to the cat back?
