XTC downpipe
Does anyone know how the xtc b-pipe compares with say ZZP and CTI.?
Also is it 304 stainless or just reg. stainless?
I am still undecided whether to the following.
1. Full 3 inch Header back exhaust CTI
2. CTI header and downpipe connected to 2.5 Corsa exhaust.
3. GMPP manifold XTC/ZZP/CTI downpipe with 2.5 Corsa exhaust.
My first question above is mainly for option #3 I am considering now. I would not want to get the GMPP manifold which does not have a 3 inch collector then open it up to 3 inches with the ZZP or CTI downpipe then squeeze it back down to 2.5 inches again. It would seem to me that would somehow not help performance.
The XTC is the only one i see that is straight thru 2.5 inches all the way but I don't know how there quality compares.

When you order, there is an "additional notes" section at the bottem of the order page. I just requested it fit a 2.5" exhaust in there and ***** emailed me to say no problem. I believe this is just a small shop and I doubt they have any stock, all pieces being made when ordered. I ordered a week ago and the order still says "processing" but my credit card still hasn't been charged yet, either.

the xtc d.p. is stainless w/ a vibrant high flow cat... I have it on my car for a while now and no leaks, no wierd sounds, and no rust... very easy to install and sounds better then the zzp (thats the only other one I heard) everyone by me has orderd the XTC except 1 person who got the ZZP and he regrets it (sounds like crap)

Yeah I am not a fan of the construction of those DPs. I am partial to the RT 2.75" catted pipe. Well constructed and nice looking. Performance is there, according to everyone who has one.
