2015 Forester XT Premium
What I like about Bobby's posts, is they're diplomatic. He suggests I go to hell, and I look forward to going there. No snark, no axes to grind. Thanks Bobby! Very much appreciated.@8lackie in my opinion, a "true" dual exhaust with ELH - equal length headers will add to the engine performance.
A true dual exhaust has dual runs all the way back to the engine. :wink:
As to non-true dual exhaust. It's an appearance thing & I'm going to guess the additional muffler will do a pretty good job of reducing the exhaust sound level.
More poop here: Single Exhaust VS. Dual Exhaust

P.S. and now I know I should be looking at Mann Engineering for a good dual exhaust.
