i think so... i can't imagine going back from full exhaust to full stock exhaust. its such a huge difference !

 

Damn the cat is a HUGE difference, I couldn't believe it when I cut my cat out.

 

when i put the 3" dp and mp on. even with stock catback i still ran 13's at low boost

 

I just need piping made, but i dont know who i can go through to get it. I want to get rid of my cats and go 3" down and mid, untill i can afford a full RB exhaust. And a fcd...

 

Well I am 3 inch all the way back now. Of course when the cat was in there it was 3 inch from the engine to the cat, then 2 inch through the cat and 3 inch from there back, so that may have made some difference too.

 

There is an exhaust guy in Arlington that will do it and he is cheap and fast. He made the cat cut out for me in about 40 minutes. It's called Arlington Muffler and Brake or something like that.

 

you don't have to worry about creeping as much with a 89 TII..... it will hit about 10psi in high gears. a FCD is alot safer though. prepare for huge fireballs out the exhaust

 

the RB full exhaust is nice but not necessary. i am running a 3" RB dp, custom mp and an apexi n1 catback. the car sounds amazing with this setup! it cost me about $500 installed

 

I want to keep the car as quiet as possible. perhaps i could just buy the pre-silencer from rb also...

 

I have no cats and it really isn't all that loud. the mufflers are RB mufflers too.
