Exhaust
 

Hey would a 2 1/4" pipe from the headers back be a good Idea for my 91 camry or should i go smaller?

backpressure is always your friend on a NA setup... so you wouldn't want to go huge on the pipe's diameter... but 2.25" should do the job perfectly. i'd say go for it. and last i checked, you have 1 header/exhaust manifold
