I like true duel exhaust. That way you can see the firing pulses of the motor coming out of the pipes, LOL. Maybe try your luck at making a set of mufflers for it and model them after the one's on the 84 truck, with the baffling inside. That would be trick there, LOL.
not sure if this idea would interest you or not, I recently watched a video where the guy built his exhaust as a single then ran the single into the side of a 1 1/2 square tube going left to right for dual outlets, it sounded pretty good.
Mark Craft who says your ever to old to have fun? If it makes you happy then why not do it? Some people play lottery some don't. I never said I was getting out of the ls stuff. But if you can teach your kids how to work and play why jot do it? I play basketball with my son why not ride mud mowers too lol
PuppetKicker You are right my friend never to old to have fun. I understand the teaching. And no better way to learn mechanics to start on lawnmowers. Sorry I replied with the post my bad
