K04 + stock SMIC and exhaust...
any forseeable problems? blown gaskets, cat, etc?
I'll probably do an APR exhaust, since I think 2.5" is about as big as I'd want with the K04, and as small as I'd want if/when I go to the GT28RS.
Would the Milltek be too big for the K04? I'm thinking it would be...
thanks...

id think itd reduce lag, less backpressure after the turbo, no? even if just slightly...
then again w/ the cat still there it prob still has some.
if anything low end torque before turbo spool prob suffered a little, but its most likely more than made up for in the mid to top end.

yes, 2.5" test pipe 2.25" borla...
although i measured outside diam, and its more than 2.5" (and thats not whre 2 pipes slide together) and its not all that thick walled, it seems almost liek that weird 60 mm tubing, wich is 2.36". may be just wishfull thinking, either way no more is needed for a K03 or K04 car, and even a couple big turbo people are running it IIRC, but could prob benefit from bigger im sure.
My test pipe made more of a difference than the exhaust i think, removing the restriction directly after the turbo.

i dont think anything 3" or less would be "too big"
go with what you want to spend, and what you think sounds good.
I probably get similar performance out of my 2.5 testpipe and 2.25" exhaust as i would a 2.75" (or maybe even 3") exhaust with stock cat, who knows maybe even better, thats a big bottle-neck only inches from the turbo outlet.
