Hello Nicknack,
I had a Miltec on my Spec-C which is a very good exhaust, not too loud under normal driving but sounded great at high rpm
In the tunnels on the way over to SSO, I think it sounded great
I now have a STi Tuning exhaust on my S204
The car runs @ 1000rpm on idle, so the exhaust sounds a good bit louder the the miltec, but the idle speed of the car accounts for a lot of this
But when you open it up, It sounds great IMO
As the car a equal length manifolds, there is no "burble", but at high rpm it almost sounds like a super-bike
I think "Mac Mac", was behind me at the Night Meet over Christmas, so he may be able to tell you what it sounds like under load at high RPM
Here you go......
