haha this is funny because i spoted this out in the other thread about this exhaust b4 this was posted. buschur raceing the only way to go imo. full 3" turbo back inner dia. and u have the option of mufflers,
buschur mufler = load and growls like an sob
magna flow = different sound not as loud
new biller muffler = even quieter, nicer and doesnt have that growl
i have the buschur muffler and its loud, smelly (bc i have a test pipe), easy to install and i absolutly ****ing love it.

Depending on your power goals the exhaust may be fine. One of my friends had his 9 tuned recently (stock turbo, cams) and found his HP curve started to flatten out up top due to this exhaust. He ended up with about 355hp before the exhaust became a problem.

my friend with a Type R, almost got that exhaust its a very nice system, but it sucks its that small.. maybe try it out? i dont think you need 3" until your over 500hp.. correct me if im wrong. might help spool too!
my friend ended up getting T1R exhaust which is 2.5 all the way through i believe, and gained like 17 WHP, on a stock 1.8L Type R engine!
you might try to customise it, but thats expensive considering you bought the exhaust thinking it was what you wanted, not knowing you were going to have to shell out more money to get new resonators from a muffler shop or something. good luck!

and there is no way that your friend gained 17 whp from just an exhaust in a b-series unless he went from a 1.5" stock cx exhaust to a 2.5" but that just means he got back the hp he lost from using a smaller than stock exhaust in the first place. i've tuned many b-series and have never seen more than 5whp gain just from a cat-back exhaust.

Thanks Zeus for letting me know about the glitch.
What I was saying was, in condensed form:
What I was saying was, in condensed form:
- Fujitsubo RM-01A is an RM-01A. There's the version in stainless and one in Ti, but same dimensions.
- If your'e worried about the diam. be glad you didn't shell out more than 2x to get the same thing but lighter.
- IMO I don't think the taper would hurt that much. I'd love to see dyno's with same car on true 3" and this one. Not to prove anyone right/wrong, but I'd be interested...
- Fujitsubo do a Super Ti which is bigger than 3". Perhaps that has no taper???

I looked at the muffler and it does have the JASMA stamp on it. I am making around 500whp so I think the neck downs from 3" to 2 1/4" is going to be painful.
My current exhaust is a UR w/ a magnaflow and w/ my upgraded turbo, its really loud. With my stock turbo, the sound was perfect.

I contacted the vendor again and I am going to return it. Hopefully, they will give me all my money back and shipping costs since they sold me something that wasn't as described.

I bought my Fujitsubo Legalis-R (same as the RM01A except the muffler is different, and not one piece) knowing about the restrictions. Despite the neck down at the resonator, I still noticed a notable power gain and it is quiet. I am just happy that there was an exhaust that gave performance gains while keeping the sounds at stock level.

You should have called me up.. I could have told you that it was not a 3 inch exhaust
