custom downpipe

[nyk4life]

i was wondering if a custom 2.5 downpipe from a muffler shop is a better than the ebay downpipes, muffler shop is charging 150. and also is a 2.5 inch downpipe a good choice for the t25 stock maniflod and stock o2 housing, and will it boost creep? thanks guys

if its a 2.5inch piping for the t25 i would think you'll be ok because if i'm right Boost creep is rising boost due to not enough exhaust bypassing the housing"??

well with a 3" downpipe with my t25 i get boost creep bad enough to hit fuel cut at 15psi at WOT but thats 3" and your only looking to go 2.5" you might be alright. What are you plans for the car????

i think hee would be ok with a 2.5.

For that price I would probably just go with a eBay downpipe. A 3" is going to give you boost spike since creep on a T25 is pretty much impossible because the turbo falls off so fast. Not saying you can't get it but you are much more likely to get spike than creep. If you are hitting fuel cut at 15psi you probably have a boost leak. You shouldn't hit fuel cut that fast.
