I am getting a set of Raptor headers in the next production run, and have been thinking of how I am going to set up the rest of my exhaust. Have been planning it out in my head for the last couple of weeks but am now spurred into action after finding a leak in a weld of a rear muffler.
From the experience of others on the forum (Daytona esp) and one of Tradewind's videos of the the 3RB without mufflers, I think the best option is probably to keep a good flowing mid muffler and let that do the majority of the work. If I do that...
Apart from there possibly being nothing to fill in the cutout in the bumper, is there any reason why I can't get rid of the drivers side muffler and just run an aftermarket passengers side? It's one less muffler to buy, and should give me a couple(?) of kgs weight saving. Everything is flexible in the plan, looking for some advice. Btw, I notice that the Gen 5 is single rear muffler.
Raptor headers
200 cell cats
y pipe into 2.5" oval mid muffler
2.5" piping into 2.5" passenger side rear muffler (a la Gen 5).
I'd be happy to pick up a late model WRX twin tip muffler, but looks like it is smaller than 2.5", maybe 2.25"? A 2.5" single muffler would be the size I need for a 3.0 NA right?
Thanks
