No more lag - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Trust Downpipe

Cat-Replacement Pipe

The advantages include more power, near zero turbo lag, especially from 2000-4000rpm, and vastly improved mpg. The mpg is so improved, I've actually started questioning the environmental-friendliness of catalysts wholesale.

I remember the day I did that to my GTT very well. Makes an enormous difference

hi guys , i`m new to the forum and only had my liner 4 months............... how much did it cost all in? and did it make a big difference? Plus do you have to put the cat back for the MOT?

cheers Andy M

Decat approx £100
front pipes approx £250 -£350
it does make a good difference as it allows the exhaust gases to escape without to much restriction. MOT depends on the age of the car

cheers hodgie , it`s a 94 L

Nick MW · 20th October 2005, 05:01 PM

Andy - if it is a GTS - about £175 for downpipe and £60 for decat.. Made a HUGE difference to my GTT as I said... If a GTR, as Hodgie said.

I think you are fine with no cat for MOT on a 94

andy m · 20th October 2005, 05:09 PM

Nick , it`s a 94 GTS T and it has a bit of lag though the main problem is traction down the 1/4 mile!

Nick MW · 20th October 2005, 05:35 PM

I am afraid that it will not help with that at all

Some good rubber on the back and suspension setup will however....

andy m · 20th October 2005, 05:48 PM

Think your right there Nick , out with the YOKO rubber me thinks...

He always has them on ebay almost everyday, and therefore the bidding isnt so aggresive. Got it for £41
