Ive been thinking lately about selling my exhaust set up.

Currently I have the Amuse header, j's test pipe, and amuse r1 basic. Ive been thinking about switching to the j's header and Amuse r1000.

My question is, what does the J's header bolt up to?

Will the J's header bolt up to an Amuse r1000?
Will the j's header work with the j's test pipe?

Or do I have to run the 70rr with the header?

 

the j's header will bolt up with the amuse r1000 as well as the test pipe. i would recommend for max performance to go with the r1000 since the test pipe will be a smaller diameter then the header's collector and the r1000.

 

I currently run the J's Racing exhaust manifold with the R1000. There is no room for a catalytic converter if you want to use the R1000 since it's an exhaust manifold back pipe. There are no fitment issues whatsoever.

 

You'd be going from a 65mm collector to a 60mm test pipe, you should get at least a 65mm exhaust or else you're bottlenecking the exhaust flow and robbing power.

Also, I'm looking to buy a J's test pipe

 

Any 70mm header back ot any test pipe will work with your J's header.
