In the past couple weeks, we have had multiple FT86 community members come in and work on entirely different approaches to ditching their mundane factory muffler setup in favor of more tenacious exhaust notes. The factory exhaust takes the snappy little 2.0 liter boxer's revs, and chokes them off to a very tame hum, so tame in fact that the factory design includes a valve that allows engine noise into the cabin under specific conditions to help make sure your driving experience doesn't feel to muted. Fundamentally, the whole thing is akin to smothering Bon Scott (AC/DC Vocalist) with a pillow, and we don't stand idle around such behavior! So that muffler came right off...
This is where the different tactics began: On the one hand, we had Christian with his BRZ who had an inline Borla muffler, and wanted to have a single exit. Jeff with his FRS however, had two can-style mufflers with carbon tips to match his vinyl work. Finally, Tracey already had the axle-back section of his exhaust system upgraded, and was only looking to change the mid-pipe to delete the resonator.
Take it to the Flo'...
Yeah, we don't really have a four point lift. Turns out, Rally Fighters sit really high, and you don't really need them over your head. FT86s though, are not very high. They're actually pretty low. We could get them on jack stands, but it was not the most impressive working position. We pushed on though, despite the lower back pains. For Christian's BRZ, we fabbed up a dump pipe option in addition to a single sided Axle Back section with his Borla muffler. For Jeff, we re-did his mid-pipe minus the resonator, and had it lead right into a new muffler setup. Tracey, we just dropped that mid-pipe right out, chopped it in half and into the trunk and replaced it all with 2.5" piping.
Currently, we still have to do the the second side on Jeff's setup, but this was our reaction to the different options:
Tracey: Starts his car with twin tips and a pure mid-pipe, Starts reving it up into the 4k-5k zone.
Christian: "I didn't even know our car could make that sound!"
The other configurations still sounded kind-of reserved, but Twin parallel aftermarket mufflers + no resonator on 2.5" pipe = racecar sound.
All these configurations will be used to create a jig so that we can recreate these designs over and over!
More to come as we finish Jeff's!
