high flow cat worth it?
im planning to free up some power on my jdm b16a and was wondering if a high flow cat is worth buying...im planning to buy a header to go along with it....will the high flow cat produce any noticable gain or will it not matter?

If you get a header with a 2.5" collector, you'll have to upgrade the cat no matter what. If you're not going to get a header with a larger collector, just use what you've got and save your money.

If you like to hug trees, yes, it will give a minor improvement in the top end of the powerband.
If you're not a hippie, a $40 test pipe will accomplish the same goal, only better and much cheaper. |

who cares when you can gain 1whp :rolleyes: For your application a testpipe is pointless. I wouldn't even bother with a high flow cat until you get more mods. |

Urethane engine mounts, or perhaps a worn out stock mount? Or no flex pipe behind header, and/or bad exhaust system hangers?
|
the shaking stopped when i got a new exhaust so maybe it was rubbing against the body
