Does anyone know where I can just buy (1) 2.5" V-band flange for a dp? I did search, couldn't find anything. Also, I wanted to make a 3" dump pipe to switch out at the track. But I have a 2.5" vband setup on the turbo. Will it make a difference if i just use basically a 90 degree 2.5" mandrel bend straight down or will I gain anything from getting some type transition from a 2.5" to 3" dumpipe? thanks for the help

 

check atpturbo.com, click the catalog.

the default honda-tech answer is that you will gain power.. the real question is if it will be worth making two downpipes.

Try Vibrant performance . They have a Tone of DYI parts.

 

This may not be a popular answer but SSAC sells V-band sets (2 bands and a clamp) on eBay for $42 shipped.
