R33 S2gtst Is It Worth Just Front Pipe And High Flow Cat Or Dump Aswel?

[boostn0199]

Just wondering is it worth just doing the front pipe and high flow cat will i get noticeable gain or should i do the dump pipe aswell?

You can buy the Dump and front pipe as one. If you saw the size of the standard dump i recommend you upgrade. Best mod i did was the Dump+front pipe from just jap and the xforce highflow cat. Makes the car more responsive and come on boost sooner.

im also interested in this, at the moment i have a hks front pipe, hiflow cat and a kakimoto 3inch cat back, with a stock dump.. will it make a big difference to change the dump, i was told not to change it as it wont make a difference.. thanks

I once had just a catback exh. I decided to upgrade the dump/front/cat.

Once i upgraded it all, im not sure whether it was just me or that i lost a little bit of responsiveness HOWEVER the boost hit ALOT harder and the exh had an angrier growl to it(no cats/reso's etc). It pulled ALOT harder throughout the rev range.

Have to be careful tho as you might get boost creep, which an ebc might be needed for then.

Can a turbo back system be done with no other mods, or is better to go front pipe back where there are no other mods?

upgrading the dump pipe will make a noticeable difference.

front/dump/high flow cat and exhaust, best mod ive done. easy fit. cheap. i already had a cat back system so i saved quite abit of time and money.

my whole exhaust on an r33 gtst series 2 uses the original exhaust mounts.

just jap bell mouth front/dump 3inch, Xforce 3inch highflow cat, fujitsubo 3.5inch cat back....

Just described my whole exhaust system to a tee

If your going to change that much on your exhaust you may as well get the dump.

Sorry for the newbie question. My mate has a N/A R34 (2.5ltr) manual, he wants to get a high flow cat and just a muffler. What size cat should he get? Same diameter as exhaust or bigger? The stock N/A exhaust I think is 2 1/4", not sure. So 2 1/4" or 2 1/2" or 3" cat? The less cell the better yeah? Thanks for any help.
