for those interested, here's my friends stock 12a with those CBR 900 mufflers.

i can't seem to get all the file of mine to upload, but will keep trying.

 

Megaphones...loud. It was in buddy's RX-3 during the 80's.

 

IMO. Fugly. What're the benifits?

 

not sure if there r any bennifits, it still run pretty good. he just wanted to see how it sounded i think and just left them on it. loud exhaust isn't an issue here.

 

The video doesn't want to work properly. Must be my charter internet connection being crap again.

It's kinda neat looking, how restrictive/free flowing is it?

 

sounds like one.

 

yeah i plan to get a supertapp for my rx7. what's the weight of that RX???

 

chi san, u being on charter the vid should stream better than for me on dialup. i don't think they're restrictive at all. it seems to run pretty well with them.

re-turbofb, supertrapps really aren't any good for rotarys. u have to remove too many disks to make decent power and then they're way too loud. that friend in the vid and i have already experimented with them many years ago.

 

looks like the mindtrain exhaust

 

Sounds pretty crappy to me. No harm in trying though.
