i recenetly put on my header/presilencer from Racing Beat. There website says that the presilencer has the necessary backpressure tube to activate the 5/6th ports. My question is why the hell does it look identical to the split air tube? I had the Bonez midpipe and that had a little tube that i connect to the 5/6th port solenoid nozzle. So how do i get my ports to work again. tying them open sucks.

 

Yep, Racing Beat uses the split air tube for backpressure just like the factory exh. Bonez racepipe just moved the tube up to the front of the pipe. Both should work, RB is just more bolt on since you don't have to remove the split air tube.

 

oh ,thxs. I thought the split air tube was for pumping air into the cat only. So what should i do with the vac hose that is on my 5/6ths ports, ( that connected to my old Bonez pipe for backpressure)?
