Hey guys I am looking at purchasing a used Apexi N1 dual exhaust system for my 1987 Rx7 Turbo. I was wondering if the racing beat Rev 2 downpipe would work with it? If not what downpipe(s) could I use?

 

Anyone?

 

No. Rev II only works with other pieces of the rev II unless you do some custom fabrication. You could use the downpipe but you have to make something custom to go between it and the cat back as I don't think their pre silencer will fit.

This should bolt right up but it's not 3". It's 2.5"

Not sure what is out there that is a straight bolt in if you want 3". Might try Ebay.

 

the stock system is DP->main cat -> catback.

the RB system is the same, but with different lengths to things.

so to use the RB down pipe with the apexi exhaust, you would need to make a pipe to bolt to the RB dp, and then the apexi cat back.
