Apex'i GT Spec Cat Back
On n/a s4 rx7 would it be ok to run a GT Spec Cat Back system, because my friend has his mind set on that muffler, we just want to make sure that this system will run alright with a series 4 n/a

how big's the piping? does he have the air pump mod done for the 5/6th ports?
is that a dual set up or single? single would be lighter and have a little more back pressure, aka a little more low end torque

ive heard the GT Spec on an n/a, it is absolutely incredible sounding, its a very mild but deep import tone with no resonating at all, a very great sounding system, power wise it should be good too

The system is a single driver's side exit. The Cat Back system does have pretty big piping dia. but the whole system starts with a resanator box then piping back into the GT Spec Muffler. The only thing that we're worried about is his 5th/6th ports, because we wanted to do straight pipe.
Here is what we have so far...

What should we do for the ports to function properly.
Thanks alot

I thought it was exhaust velocity that gave torque... not backpressure

back pressure has NOTHING to do with any kind of power, back pressure is a bad thing, no back pressure is good, none at all velocity is what you want, scavenging is what you should strive for.
well, just the note, back pressure is bad
