exhaust de-catting - what down pipe do i need?
I'm currently running a full milltek 3" exhaust system with sports cat in the down pipe.
If i want to remove the cat does anyone know what make/model downpipes will fit?
Cheers,

According to scoobyworld (I think) the sports cat downpipe is very close to the de cat pipe in terms of spool up and bhp. It also means that you will be road legal and pass emission tests.
After that any 3" system will mate to the Milltek as they use standard flanges.

Anyway, there seems to be some debate as to how much bhp a Newage gearbox can take - near 350bhp or 300bhp ??

For how long so far Midlife ? Take it you don't do a lot of launches !!

I tend to use the car as a daily driver with occasional use over to Newcastle
It often has the kids in as well LOL
The other thing is I havn't paid off the car loan yet so I have to be carefull
Mind you Ninnybobs owns his 400BHP bugeye and has been known to drag it on standard gearbox / internals / clutch !!! He has had to change the clutch recently though

Agree that with the STi 6 speeder, and you'd have to be spending serious money on the engine to break it.

Ninnybobs seems to have about the best record for power/torque over lots of miles on many standard WRX bits.

So if i went for any significant increase in power I'd risk killing the gearbox eg a VF35 and mapped again to suit ? (it's already Ecutek'd).

by the sounds of pm'ing NinnyBobs might not be a bad thing to do with some questions
