3 Inch Dump

[ClutchBurndout-:(]

does anyone know where you can get 3 inch dump pipes for an r33? also, is it worth installing on a 12 psi stock turbo with a 3 inch exhaust? cheers

I can think of at least 10 places off the top of my head...have a look at the forum traders for a start....or google is your friend

Very worthwhile installing. One of the best gain for $ mods you can do

damit, last time i asked that question to somone, they said, you shouldnt do it because you should need some restriction in your exhaust, but im running 12 pound and at about 4-5 thou, it flattens off, now im not the most knowledgable in the art of turbos, but could the standard dump pipe be whats holding it back and making it flatten off?

Def get a dump pipe.. pref bellmouth - have a look under the traders section.

Just a word tho - You might get some boost creep. I used to get bad creep, but that could partially be because i dont have any pussies in my exhaust. Fixed with an ebc and pulls 10times harder then with the stock solenoid or the turbosmart boost tap

^^ boost creep happens with poorly made split dump pipes, the wastegate flap fouls on the separator on the dump. Hence your boost goes UP with RPM.

You can't fix boost creep with an EBC, if your wastegate will only half open then boost will go up no matter what the EBC does. You're describing something else, like boost spiking caused by a shitty bleed valve (you set it to 10psi and it spikes to 12psi before settling down to 10).

Recommended upgrade.

www.justjap.com sell JJR 3" stainless steel bellmouth dump/front pipe for $199. Do you have a 3" high flow catayltic converter as well?? ...or no cat will do.
