J2 engineering exhaust review - Page 4 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

NYCsubaruBRZ · 06-24-2013, 07:23 PM

i had to cut and bend the ***t out of the exhaust but its on and now it fits.... sounds sick... but maddd issues with fitment... I HAD TO BEND ALL THE HANGERS AND LENGTHEN THE MID PIPE.....

they need to screw there head on straight over there at J2

anyway, the hard part is over.. and its on... sounds good.... a small loss in power at low end... a slight gain at high end.... im going to make some custom adapters to up the back pressure a bit and and have a few back pressure options... im going to make flange adapters that have different size openings so i can play around with the back pressure and hopefully find a sweet spot.... this is where the weird x pipe design that they made comes in handy... it will be interesting.... i might just block off one side.... ill re post some data when i get time to fab them up.

Bumping this, because I just checked on eBay and it looks like the price has been dropped, quite a bit:

$398 shipped for the exhaust and front pipe. Pretty ridonk.

I've heard a few different sound clips from the J2 exhausts.. I loved all but one of them.. one of the videos it sounded too much like a lawn mower.. I guess it makes it sound more boxer.. but to me it sounded more harley.

The other clips I heard sounded great.

You just got the front pipe right? What is the rest of your exhaust system?

Actually.. The exhaust will get louder with time as some of the packing in the exhaust shrinks, burns or gets blown out allowing more flow and noise.. It seems louder at first because its compared to stock.
