@@rhd_ron oh man what a flashback. My last system on the EM1 was the Tanabe Super Racing Medallion. Took it off to weld up the B pipe at an old shop I worked at and left the muffler there. Ended up slapping on a stock Si muffler due to local authorities. Anyhow its probobly still hanging on the wall at Sage Autosports....if that place still exists.
Unfortunately not, we haven't had the car on the dyno. The website suggests around 12-15 hp increase with no tuning. I can tell you the car is MUCH more responsive with the intake. Thanks!
