i plan to go on k04 with catted. the vendor is selling about $1280 for awe tbe.
If he is offering you AWE turbo back for 1280 thats about $100-$160 off their website.
Anything above the stock turbo i would personally do a 3" downpipe and then let the catback tapper to 2.5"
Bigger turbo = more flow
More flow = bigger pipes(IMO) so not to build to much back pressure
I think the best combo is a 3" downpipe reduced to a 2.5" catback.
He's right though. The only down side to a 3" dp is the tq that is stolen from you in the low end. You'll notice it for a while...but the car will be noticeably more responsive as you build boost. There's a trade off for everything! :23:
So you are also recommending 2.5" dp for someone who intends to stay k03?
Pricing wise thats dated. And i think a few of those companies stopped selling. But sizes and whether or not it is mating to stock catback is still valuable info for people.when I see this question I always send this link. Might be a bit dated now doe
