de-cat

[Tfsi_Mike]

It passed

Was that a std exhaust, i mean does the miltek tbe still have the ceramic precat???

Lol thats brutal Jonny!!!

A shameless way to treat a new car.

Naaaah..   Listen up, im leaving my house in about 10 mins.. It should be loud enough for 'most' of town to hear it now haha..

Anyways, back on topic.. Going from a Sports cat to de-cat will help power and torque as Hurdy said.. I have found in almost all cases going de-cat reduces noise when cruising, but makes the car louder on throttle.. Usually, less of a boom too with de-cat.. More of a raspy note..

Hope that helps..

A Decat to Std Catback would sound great IMO

Should also provide the same performance as any aftermarket TBE on a K03 motor.

The gasses cool as they travel through the system and effectively shrink, not requiring such a large diameter to travel at the same speed. The Std cat back is 2.25" internal diameter on a GTI (prob same on VRS) and should not be restrictive.

It might be worth getting your MOT done just before you have the decat installed

what would you guys reccommend decat wise for my k03

a 2.5" piper Decat downpipe
or a 3"Blueflame decat downpipe

I think 3" downpipe.. As it has been said, when the EGT's are at there highest you need the larger diameter..

cool,  thats only £225 as well.

I now need to look into a good but quiet(ish) intake.  Last time i had the full non res TBE, and ITG and the missus did nothing but complain. 

I want the same performance as before with less shouting about it.  which is always handy as in medway you cant drive a mile without seeing a cop car,

no its just the bottom cat on the miltek. have you bought a new decat pipe or are you butchering the miltek like hurdy has done so you can do the swap at MO time

Butchering the Miltek with a flanged stainless section and flanging the Cat.

make sure you get yourself a few gaskets for when you swap over.
