Re: X-pipe before catback? (Midnight)
Depends on why you're doing it. It will probably add some midrange torque. It will definatly quiet down your exhaust a little, and reduce decelleration "pops". I replaced the factory H pipe with an X pipe after doing Corsa Indy cat back. I liked the results then, and more so now with long tube headers. Sounds great but so loud that I draw every cop car for blocks around (driving an "arrest-me-red" drop top, somewhat speedily, is bad enough) :D
IMHO if you like the sound now, it will be too subdued with an X pipe and factory exhaust.

Just witnessed a before and after dyno run with X-pipe along with 40 witnesses, Lost 5 hp.......The computer was reset each time so don't use that as an excuse. Also, it was done by an exhaust manufacturer that was trying to sell them.

Re: X-pipe before catback? (Midnight)
Well, there really arent any pops right now, and I don't really mind the way my other car sounded when burbling. So is there any advantage really? If it's losing horsepower, what good is it?
