cat removal replace w/ midpipe questions...
I have a 94 rx7 that is almost stock only mod is a downpipe that removes the 1st cat. I am going to be putting a racing beat cat back system and thought i would go ahead and put a midpipe, they have to different styles one has a resonated section and the other is a straight pipe. i just wanted to know which i should use? i dont have any problems with noise or emission tests. I want to know if you think its going to be loud without the resonator or just any constructive comments. thanks...

If you go with a straight through midpipe it will be much louder and it will smell a lot more. Going with a straight through exhaust should definitely go along with a better flowing intake, a ported wastegate and some sort of aftermarket ECU (PowerFC). At this point all you need is a better intercooler and you will be in for a serious power increase.

Keep in the main cat on, unless you plan to open up a can of worms. You're better off going with all of the other bolts ons first, then delete the cat last. With stock twins/internal wastegate anyway....

I have a 93 fd, had a doodie catback, and a pfc, all of that b4 I took the cats out, I'm sure the pfc is the main thing to do b4 pulling out the main, im sure everyone else will comment on this, but dam it made a huge difference with how hot the car ran, the power curve, and I am in cali where we have the worst tuner car friendly gas on the face of the planet.....but they are right you dont want to over boost with out more fuel, the **** would def. hit the fan!!!

I considered buying his restrictors but wound up with a metal cat instead. Got the added benefit of getting rid of the nasty smelling exhaust fumes.
I'm selling it if anyone is interested. Built another one

I've got a straight through to my stock muffler (also intakes n' walbro fuel pump) and haven't blown my engine due to boost creep. Are there any other ways to safely boost w/out a PFC (don't have the funds right now) or restrictor plate when I kill the muffler?
