I have a chance to buy a used Fujitsubu exhaust for a good price, and from what I have hear they sound really good.

Only problem is it shows a 2.5 downpipe to a y-pipe, and back to dual 2.5 pipes to the mufflers.

I wanted to get this exhaust for the rareness and the sound, but if it hinders performance than its useless. I will be going for 350ish whp, but for the next year just the stock turbo 13psi.

would I be better off with a apexi GT spec?

 

you mean the one that me and another person are bidding on and the price will jump to at least triple of that?

 

13 psi... Stock turbo... yeah

 

i guess that could be the same exaust. but would it be a restriction?

Oh and whats wrong with 13psi, I plan on putting 4k miles on that turbo, so I could care less if it craps out.

 

I wouldn't go over 10-12PSI on a stock turbo. Granted I want my car to last >4k but, past 12 it starts to blow some pretty hot air. You may make more power at 13 than 12... you may not.

 

13 psi is fine,,,, 1 bar is fine on a fmic...
the question is,,, would yuou want ot kill yoru turbo?

 

this turbo is just for breaking in the motor. so Im not too woried as long as it makes some power till march.

so it seems your bidding on this exhaust, good luck. but I still want to know if it is going to be a restriction for a mid 300hp goal?

 

your not really breaking in anything if you are running 13 psi.

A 2.5 in downpipe is pretty small.

 

why would you guys want that exhaust? It looks pretty restrictive...3 resignators?

 

which one are you looking at? I have the legalis R catback and its pretty nice... but honestly a little expensive. If you want I can post some links to pics of mine. It does seem a bit on the restrictive side, but its pretty quiet and is an upgrade from stock. Depending on the price, to be honest, it may be too much. Although the quality of the exhaust is wonderful, it is alot to spend on an exhaust.

 

Arg, I can confirm not one stock turbo has made 300HP to the wheels.

 

would love to see pics

 

The resonators are straight through and cause practically zero restriction to flow.

I have that Fujitsubo cat-back and really like it, although I suspect that some of the sound absorbing material has burned away due to age, because I'm sure it's louder now than when I bought the car ~4 years ago. That one looks like it's in very good condition though. My mufflers weren't nearly that shiny. They had a metallic gray paint that was pretty faded so I repainted them semi-gloss blank and machine-polished the SS tips.

I'm pretty sure I measured mine at 3" before the Y, then it splits to two 2.5".
