Title: miltek sports cat question...
Post by: golfgtidan on 02 April 2009, 19:46
firstly sorry for not using the search but it would probably take forever trying to find the answer searching through all the miltek threads.

Basically is it posible to fit a sports cat to the standard cat back system on a agu? i no as a rule you normally change the cat back then do the cat but i was wondering if i could just get away with changing the cat and getting the same performance as a full system?! is this a possible thing to do and would it cause any problems?! if so il be buying a cat asap then off to saint nick for remap part 2!  :laugh:

cheers all

No cant be done - bigger bore pipe also you then just put the 'bottle neck' on the rest of the system.

Need the Full system TBH how about custom a made one?

not strictly true Rich..........

Milltek can and do supply a reducer to allow the sports CAT to fit the standard system

its not advisable as when you come to fit the rest there is a good chance the reducer is stuck because of the constant expansion and contraction of the exhaust due to the heat  :nerd:

if a cat back system will fit the standard CAT "hence cat back" then how comes a sports cat wont fit standard cat back system?!

Mines custom. I see your from Plymouth. I got mine done in longlife. Full system was £550 fitted.

Most members on here heard it at the rolling road, what were peoples views?

Personally I thought it sounded nice, not too loud but a little bit deeper tone to the milltek's.

Performance wise, I got good results which were similar to a similar setup with milltek (keiths) so don't think there's much in it other than price.

I did wonder this myself, but apparently Milltek do a 3" cat-back system to go with the 3" SC/DP & a 2.5" cat-back for use with the OE cat.

Oh yer  :grin:

At the end of the day it's just a metal pipe of a certain diameter, providing it's fabricated well it doesn't matter what company makes it. Theres nothing 'special' milltek do to there systems other than make it well, but pricey too!
