id get the high flow cat, someone on the board got the coilpack, and said he couldnt feel the difference
later

yea i just figured i might cause i got msd wires and ngk bkr6's but i think ill go withthe cat

geta test pipe if u dont go through emissions..
testpipe.com

Someone here (VX-100) got the high-flow catcon, and didn't feel a difference. I would put my money elsewhere. Maybe put that towards an sAFC?

Defenitely get an SAFC or AFX computer before a high flow cat. You need a good deal of mods before the high flow becomes worth it.

But if you are going to go for it and you don't have emissions to worry about, then a test pipe would be cheaper and provide more performance.

wont the test pipe make me loose low end torque???

I do not have a test pipe, so I can't say for sure, but my *guess* would be no.

Since you are all motor, I don't think the coil pack or high-flow cat will help much. If you still want to replace the cat-conv., then I'd recommend getting a straight pipe instead of a testpipe or cat--unless you are worrying about smog testing.

straight pipe is a test pipe, anyway i just went to Extrme motorsports today and bout there flanged 2.5 inch high flow, since i go there so much and i got an extreme sticker on my rear windshield, they did it for 100 bucks with nut and bolt kit, well anyway my AFX UDP came in today also so when i get home i am gonan out in my UDP and cat, ill post what i notice, ill do one at a time to see the diffrence..
