Looking for an aftermarket b series header for my gsr, im not sure if b16’s or ls’s are the same but i believe b16’s are shorter.Need something asap.
post pics and a price if you have anything
why cant you just use the cat instead of the test pipe?
it wont bolt up to the exhaust, and the stock manifold is restricting some flow of the motor.
I have a jdm 4-1 header i just took off my gsr motor in real good shape pm me if your interested
