don't have one but as far as i know its an awsome header with probably the best gains but its a PITA to install. So unless you have some GOOD experince and tools and maybe a good friend with two cases a beer i would say to have some one else do it.

Do a basic search on things your looking for or read around in the 2.4 section. A lot of info is there for you to read that has been covered before.

Well from what the LSJ guys say with custom tune stage 2 they get around 20hp gains...so were probably looking at around 12-16 possibly. It's a nice header but gonna be a pain to install. My CA header was a pain and it's 1/3 the size, I think for the JBP you have to drop the sub frame but I'm not 100% sure?

i have a 2.2 and it sounds like a beast its crazy i dont know the gains yet but i bought them when they had that crazy sale for 300 it is a pain putting them in i had to drop the axle on the drivers side and then it took me a while to take the studs out but after that it was not to bad. so for anybody who owns a 2.2 im letting you know it fit my car cause jbp didnt know at all, so im not getting any recognition from them

Isn't the collector size on that header 3"?

3" = on a 2.4SS unless its supercharged.

No car with 173hp needs any 3" exhaust components. My buddies 305whp (dyno proven) STI has a 3" exhaust........so why would we need one? lol
