When I was like 18 I had a 64 sunroof and one of the few mods I made to it was a single quiet exh. It looked cool and sounded cool and was cheap as hell at the time. Now I got this 66 sunroof and it came with a mondo muffler. At Idle and around town it sounds much racier than the quiet from my "YUTE" ever did but at speed 45 and up, it just makes the whole interior (and my head) vibrate with a very loud LOUD soundtrack. Even my kids (who have been subjected to 3 years of tri mill exhaust on a convertable tub buggy) say "Dad this thing is too LOUD"!! To which Id reply "WHAT? I CANT HEAR YOU OVER THIS DAMN EXHAUST!!!!" So the search began for a single quiet (used as I am still trying to pay of the initial purchas of this thing!! Thanks to all that have helped me almost make it by buying some of my old but beloved crap!!).  Well as usual it was Ebay to the rescue, yea Ebay!! I found a single empi quiet that with shipping came to 36.00!! It arrived and was as described (like new man!! cant have more than one season on it).  I installed and started her up this morning. WOW What a diff. It sounds very pleasent now. Of course at speed I can now hear all the wind noise from the sunroof that will no doubt drive me batty (note to self, fix sunroof seals).  ALso the sound really took me back 32 years (damn Im getting old!) It is a very distinctive sound that I really have not heard in a long time (dan smiles and thinks back to 80's music on sparkomatic radio)   :)
Anyway another thing happened to fix itself and im real happy about it. With the mondo, the engine had a real hair trigger between low speed idle circut and mid range circut  that would make you go Oof and make you real careful on the throttle. I found that by smashing the gas at just the right time got you past it smoothly. The single quiet seems to have smoothed that right out of the motor (assumed that the duel carbs were not set right and was going to fix next spring). While I still intend to tune the thing to within an inch of its life next spring I gotta say it was a nice drive. I dont think too much power was lost either. Any that was, I dont miss, pulled up to 70 like nuthin just like before but without the boooming.  Well just wanted to share. Everyone have a great weekend.
