N/a b13 help!!!!!
 

Hey guys I'm new to the rotary life, I have a question, I have a 13B 1988 convertible rx7 my plan later on down the road is to get it bridge portes and turboed but the dilema I have right now is that I need a new exhaust but I was wanting one that would be compatible with the turbo and bridge port I was planning on doing down the road want I'm trying to get to is I don't wanna buy an exhaust now and later on have to buy another so my question is, "what exhaust can I buy that'll be able to go one later once I get a turbo?"

you'd be better off waiting, an exhaust suitable for a turbo will be extremely loud on a non turbo.

exhaust size also depends on your turbo size, generally 3" singles work for a rather broad range up to about 500whp though.
