Bonneville America Forums Forums Technical Forums Exhaust TORs Improvement

I have a set of long TORs, the kind that are not flow-through. If you ran a long dowel into the first baffle pipe the stick would come to a stop at the next baffle. The exhaust tone was fine, but I wanted a little more volume, and bite, for sound. I got a 4 foot length of re-bar at Home Depot for $4, then sharpened one end of the re-bar with my grinder til the point was like a pencil-point. Then ran the sharpened end into the first baffle pipe til it stopped at the next baffle. Taking my mini-sledge hammer I slowly drove the rebar until it pierced that second baffle plate, then kept hammering until the full width of the re-bar had penetrated. I had to use vise-grips to twist the re-bar out. Repeated the same procedure for the other TOR. Started up the bike and WOW, what a great sound...it's perfect. My plugs were always a bit sooty before this mod, but now they are a perfect tan color. Best, and easiest mod yet.

Nice work Robin

Is this the start of your mods then?

Great idea! Glad things worked out for yah. Those home made mods are usually the most satisfying.

Thanks....actually, I've done a few things, mostly functional improvements. Engine performance-wise, I use a K&N air filter, and I modded my snorkle (cut the bottom off below the housing mount, and cut the right side off the snorkle mouth. This allows concentrated airflow, yet prevents any rain water from entering the airbox), and now the TORs mod. I've noticed increased performance. Have no need to play with the carbs. I'll post a picture of my SM.
