Dumb question, I know... But I'm interested in buying a test pipe for my N/A to rid the cat (no emissions here) but it's made for a turbo FC. Are the cat sizes the same?

I could just measure myself, but I just moved away from home two weeks ago and don't have anything to lift my car high enough for me to get under it. It's a 2.5" pipe, btw.

 

They do have separate part numbers so I'm assuming to say they're different. I don't have a main N/A cat to compare with my TII one at the moment.

 

I got far enough under under the car to measure 18" from flange to flange.

 

n/a and turbo main cats are the same length, so yes it should fit.

 

It should fit. im in process of making a pipe from RB header and exit to the passenger side. Been thinking if I should get a cat back or just a pipe thru it

 

Those are gonna replace my clogged up stock cat btw

 

Perfect, I'm ordering from Japan through a member off here, so I wanted to make sure before getting it and then not fitting.

I want to basically straight pipe my car. I love being loud and obnoxious, but the girlfriend... Not so much. I'll also be buying a header soon. Whatever you do, get a video of it!

 

will sure get you updated. I want to have a nice deep tone to it, sound kinda like apexi N1 but I dont want it to look like a fart can

 

youve never heard an n/a rx7 straight pipe have you? or youre 16 and dont care...

 

I've watched videos. No rx7's where I live. Seen one other FC when I lived back in Sudbury.

Fully aware it'll be loud as ****, but that's sorta what I like. I like the attention, even if most of it is negative. I also love the sound. I don't find my current exhaust is loud enough, but I am a bit worried the test pipe will be too loud. Even if it is, I could always slap the cat back on. I'm getting the pipe cheap, so not a big deal. I'm 20 and in college, still have time to enjoy not needing amenities and such.
