Ahhhh, that's my stealth mode!
I was running a straight-through Stebro type resonator but it was wayyyyyyyyyy too loud, after a while you just couldn't take it
. I added another real muffler before the resonator so it is a little quieter but still a little bit too loud. Seems like all the sound just comes pounding back at you, trust me you can't appreciate it on the vid (I think my son the videographer absorbed all the sound
).
The motor is at least a 1275 (have never had the head off) over 200lbs. comp with a big cam. You can hear it loping when idling at the top o' the butte. I have been steadily de-tuning it to get it more driveable in traffic and on our low octane fuel. Engine was an unknown when I got it but was semi race prepped judging by the car it was in and made heaps of power with twin SU's but hardly ran below 4000 rpm!
Much tamer now with single HIF carb and much retarded timing but still not very pleasant in traffic. Very satisfying to drive with instant response - has ruined my son and myself for driving any other cars!
