Hooked the mic up, slapped a 74 rear plate on the car and ran it in the garage a bit. I haven't had the chance to run her in a while...so she spit a lot of water.
Over all I'm not particularly satisfied with the mic I've been using so I'm looking into more options, this is kinda a base line, but I know how everyone loves to hear engine noises.
There's still a little rattle from the driver's side pipe so I'll probably need to adjust the hanger a bit on that side as well.
Speaking of which here is a picture of the hanger.
...all I did was change the L bend at the top of the hanger to move the tips down and away from the valance.
