So I'm trying to put the finishing touch's on my Dyno Don dual cat Y-pipe and I'm having a hard time sourcing a decently designed 2-1 merge y-pipe. All I can really find are the likes of magnaflow, flowmaster, etc but they are designed as a formed Y-pipe rather than a true merge at 15-20*. Where is everybody sourcing the mandrel bends, merges, etc from?

 

Like this? http://www.summitracing.com/parts/JEX-U6-6/?rtype=10

Kind of small but couldn't find anything bigger that wasn't the formed type

 

I just run a flowmaster Y on my car. Wasnt aware there was a performance disadvantage there. I dont have any regrets with my setup, though. The flowmaster-Y is a nice piece. That pipe above is crush-bent too.

 

Flowmaster Scavenger Y is one of the best made, like said above, the first pic is total crap and will kill all velocity.

Request a catalog. They can do custom stuff at whatever angle you want.
