Hey guys,

I`m looking to buy a RB exhaust setup for my new SA. I previously had a collected header setup with two inline precilencers into a Ractive muffler, I want to go slightly different this time and try a long primary system. The RB Road Race header and the street port center section and a magnaflow muffler. The info I can`t seem to find is, what is the outlet size out the center section? From the RB pics it looks like it is collected at the end, but I`m finding other people say that the collection happens over the axel. I want to order this style Magnaflow if I can because it kind of emulates the stock look, but I need the pipe size to get my order going.

Thanks for the help

George

 

The center section has two 2" outlets. In the full RB system, they are collected in the main muffler section to 2 3/8". For your setup, just get a good dual 2" to single 2.5" collector and a 2.5" Magnaflow.
