2.5\" Exhaust

Im wondering how much of a help/hinderance to my performance a 2.5" flex/exhaust from trubendz and a kamakazi raceheader would be to a basically stock focus (only power mod is volant w/ svt snorkle).

My eventual plans will probably include a JRSC and the FR head and FR stage 1 cams, so I know the 2.5 is what im going to want for that. Just want to know how much it may help/hurt me atm since I wont be getting any of that fun stuff to late spring early summer.

You'll be all over the top end. Low end will suffer, but the area of the HP curve should be the same...just shifted up a tad.

Re: 2.5\" Exhaust

Also does anyone know where I can find a kamakazi race header or magnaflow hiflow cat (to weld into the exhaust)

Re: 2.5\" Exhaust

Can I get the 2.25" exhaust and add a shorty header and hi-flo cat to that, or does it have to be 2.5"? reason I ask is because I'm not sure how many mods I'm going to be doing so I was thinking I'd go with 2.25 and see from there.

2.25inch is good for a N/A zetec. If you have heavy N/A done (head,cams, etc.)2.25 or 2.5inch would be good. If you have a boost application 2.5inch, or 3inch for high boost.
