So im going to order my pipes to make my turbo downpipe, and i was going to order a 90 degree pipe with a 3 inch radius bend... im just curious if anyone thinks that may be too tight for optimal exhaust flow? what do most higher end downpipes use for radius bends?

 

I found on one setup I had a 90 deg. bend just off of the exh. housing and I believe it was the cause of my irregularly high exhaust temperatures. It was 3in in dia. If possible, in my opinion avoid using a 90 deg bend.

Cheers,

Blaze

 

due to my setup a 90 degree bend is necessary, im more worried about restricted exhaust due to how sharp the pipe bends down...

 

Won't really matter, yeah you might see a small difference but nothing to cry over.
