Why are you going with a 4" downpipe? Unless you plan on making over 1000 horsepower 3" or 3.5" is fine.

 

oh, i thought he meant 4" radius

 

that is what my housing wants, also my v band is 4" it cant hurt any...

not totally true...although depending on his setup 4" is a overkill for most...over on supraforums they did a test and found SIGNIFICANT gains from switching from 3" to 4" and even from 3.5" to 4" on a car with over 700whp...supraforums has been down for a week or so due to a hacker so i cant get the exact info, but it was a big HP gain

 

Have you tried calling your local diesel truck shops? There are a lot near where I live. They have lots of cool turbo parts. Though they are kinda huge for my crx.

 

thats funny you say that because that is where i went and i orderd from them only 100.00 for 2 ubends that are 12" straights and a from pipe to pipe in center is only 4 1/2" so that is cool since i was qouted for other sources like 75 each for only 90 degree bends.

 

i should be able to get them done pretty darn cheap
