I have an 87 N/A and im getting new exhaust and i want to know if the rb header,bonez highflow cat,and the corksport exhaust will all connect with out any problems because i heard some where that if i get the rb header ill have to get some thing else that eliminates the cat (or something like that i dont really remember).

 

the header wont bolt up the the Bonez high flo cat pipe. You will need to do some custom fab stuff for that. Or I heard Mazdatrix has a shorty cat pipe for the RB header. As far as the CorkSport exhaust, it looks like an awesome piece!!!!
