Hey Denny, do you know how it makes good heat with no baffle? Usually open flowing exhaust makes poor heat.
Thanks,

Not sure why but the normal floor heat is run through a SCAT tube under the front seat to the back. I checked it with a IR temp gun and it was over 200 degrees. I can only run it at 1/3 -1/2 open or the back seater complains it is too hot. I think Web is on the right track. I have the heat robber cuff on the front crossover tube then the air goes back to the muffler, the top 1/2 of the exhaust stack also has a cuff so you get a lot of surface area. My back seat heat box is mounted high and ducted to defrost only. I usually don't run it wide open because it gets the GPS too hot. You have to be careful with that back seat SCAT tube, had a buddy hunting wolves with the shells in a bag on the floor. When they got back home they found some of them had started to melt from the heat. Another buddy had the bottom of he's insulated hunting boot start to delaminate, he did not realize how hot it was cause of the insulation. DENNY
