Hello.

I have a 1986 RX-7 N/A and I am interested in upgrading the exhaust.

Does the RB presilencer and cat replacement set up still provide the necessary pressure to open up the ports??

Also, which would you reccomend, the RB setup, or the RX7.com Bonez high flow cat system. I don't have emissions, so I don't need to worry about the cat being taken out.

Thanks.

 

Put this in the 2nd gen section and someone will answer. Also, you can just call Racing Beat and they can tell you, alot easier and more accurate if you do it that way. Just go to www.racingbeat.com & the # is right there.
