i actually received a 3" 02 housing.. .and the bolts couldnt go on due to the tight 90 degree angle.. (tried everything in the book... including taking some of the studs out)...
i'll eventually go with a v-band (3") and have the local guys from fully built help me out w/it (and porting/opening the exhaust diameter a lil more)
good luck w/it... i'm definately down as long as the price is right..
i've wanted to get a 3" donut from RRE (roadraceengineering) and get my welder to fab one up with some larger diameter flanges...
funds are low lately... so its all on the back burner...
cheers and good luck... i've subscribed....
This why you use a smooth flow adapter coupler. This way I can go from 2.25 to 3" very smooth with out having to use different v-band clamps or more expensive flages. I will post pictures when we are closer to getting something done here.
