is there anything i should be aware of when installing a downpipe? i installed my catback on my own and it took me 2 and half hours cause i hit a few bumps on the way.. any advice?

also, i'm gonna buy a radiator VERY soon and i still cant decide between fluidyne and koyo.. i keep getting different opinions from people.. any thoughts please?

 

Go buy a can of PB blaster and soak the hell out of the nuts and studs overnight before you do the job. I would suggest romving the downpipe just to give yourself a little elbow room.

As far as the radiator goes I really like my Koyo (it is the thickest) but it does take a little fitting to make it work. It is not too difficult though.

 

yeah, go buy some pb blaster, and soak the **** out of those bolts and let it sit over night. Do not try it with out it, you will end up breaking off a bolt.
Dont forget, you can get to the bolts from the engine bay "up top" and the rest you got to go under the car. Good luck
