boostn0199 Posted January 11, 2009 Share Posted January 11, 2009 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?

krzysiu Posted January 11, 2009 Share Posted January 11, 2009 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.

Ultimategtr Posted January 11, 2009 Share Posted January 11, 2009 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.

TALBO Posted January 11, 2009 Share Posted January 11, 2009 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?

PWND Posted January 11, 2009 Share Posted January 11, 2009 upgrading the dump pipe will make a noticeable difference.

vidospace Posted January 11, 2009 Share Posted January 11, 2009 If your going to change that much on your exhaust you may as well get the dump.

BaysideBlue Posted March 1, 2009 Share Posted March 1, 2009 (edited) 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.
