Well I have an 04 Sti so far what I've don't to the car is minimal, SPT intake, Seibon Carbon Fiber Hood, and boost gauge. However after much deliberation I decided to go with the Fujitsubo RM-01A catback exhaust. It comes in 2 weeks I just can't wait. I know this exhaust is worth due to the price $900. Anybody have this exhaust on your STI let me know what you guys love about it. And what's the HP increase? Thanks.

 

I have it on my suby and I love it. Here is the only thing though did u get the usdm fitment? It actually bottle necks a little to the dp so you may want to take it to a muffler shop and modifiy it to be 3' all the way to the dp. It's the greatest exhaust system I've ever owned because I never get hassled by cops because it's sooo quiet and it has always performed really well!

 

Yeah I bought the USDM version and thanks for the info I'll take it to get that fitment. Got any pics.

 

Check that its the JDM version will I have any problems with fitment.

 

if u get the jdm version u will have problems unless u have a jdm dp. The length of piping is different. here is a pic I took just today actually

hahah I like to keep it dirty for more stealth. hahaha

 

That's a nice a** shot of the STi. What bout gains notice it on the top end?

 

it's not an sti it's a super modified wrx. I made 328whp on the car so yeah I would say it works pretty well thats on a very low reading dyno.

 

first of all id like to say CONGRATS! this exhaust is hands down a must have for us in cali and man is it awesome.

i had the jdm version but alls i did was take it to a local muffler shop and they cut it to fit the usdm downpipe

ive had the exhaust before it was ever released in the US and have had zero issues.

the best part is being able to drive past cops without fear.

def. worth every penny from finish to fit and performance to esthetics.

here is a pic of it on my 03 wrx

 

I think that's what I'll just go do that take it to a muffler shop and have them cut and weld. I really don't want to put out that money for a JDM downpipe.

 

btw
the jdm dp is 3 inches shorter than the usdm dp

(i just had my usdm dp cut to fit a jdm catback 2 days ago lol)

congrats on a nice exhaust though!

 

Congrats on a nice exhaust, I also have a jdm version of the exhaust. I'll try to get some pics up if I have time.

 

It is indeed a nice exhaust. Quiet and subtle enough for strict CA.

here's a random pic of mine.
