If I get the bonez race pipe-it replaces all cats-right? Will my 6th ports open normally still, do they have an outlet like the rp headers and presilencers?

I need to place my exhaust but don't want to lose the ports opening normally.
thanks
oh, this is on a 86 2+2

 

I have the race pipe on my 89. I think they fit 86-91 but thiers no air pipe. My 89 does not work off backpressure from the exaust thou so I didnt lose crap. You will have to find another way to open your ports. Thiers alot. I will sell you mine for 100 dollars. I have a custom pipe that fits thier so I can replace it. I also am going to put on duals soon. As for the rp race pipe, it does replace everything with a streight pipe w built in presilencer. It costed me 185 with shiping and tax. This pipe will save the life of your engin. My stock cats are what costed me my rebuild after 140k miles even.

 

I have a Bonez race pipe on my '86 NA and it actuates the 6ports perfectly w/ the stock catback, no hesitation. You may have to clean, lubricate and manually actuate your actuators a bit to get them unstuck if they have been inoperational as I had to. In retrospect, since the racepipe is non emissions anyways I wish I had bought RB header and midpipe for the extra power it provides and lighter weight (negates stock reactive exhaust manifold) although it is louder.
