Does anyone make an under seat exhaust on their '99-'04 Sprint ST?

Or does anyone have one installed that they can tell me about?

Are they reliable, hot, easy to install? I was thinking about doing one, but they seem few and far between. Does anyone make them anymore? Probably not. I always thought they looked pretty cool on our years Sprints


Thanks

There are some off brands sold (ebay) but I wouldn't trust those. Trident used to make one. Maybe look them up amd see what they have or could make for you.

Just so you know, how do you want your right calf and thighs, well done or burnt. Under tails are hot and the link pipe hotter. I would get a heat shield between the cans and seat. Summit racing sells kits. I would ceramic coat the link pipe for heat reduction. There is a spun glass sock that the link pipe can slide into. Just giving you the heads up. Ask any ducati owner that have undertails .

Speaking of heat...

I have under tails on two bikes right now. My Speedy has SC Project carbon cans that are basically below and beside the seat... they get so hot that they started melting my gym bag on the seat, and I can feel it through my riding pants, only when I punch it. I absolutely love those cans. They're gorgeous and sound the business. they were also almost $1000.

The Daytona has a Black Widow that is tucked under the seat. The pipe doesn't get hot by my leg really, but I have ordered a carbon fiber heat shield, mainly as a trim piece.

So it's not that big of a deal unless you wear shorts. Who doesn't like warm buns?

How much did the Black widow run you? They haven't gotten back to me yet. Maybe I'll call.

I commute with tank top, g-string, flip flops and a spaghetti strainer on my head, so I'm basically cool enough as to offset the pipe heat.

just kidding, thanks for the tip

The heat alone from the engine when the fan kicks on is a roaster on hot days. I took a spin a couple weeks ago and it was in the high 80s and that vent was hot hot hair dryer. Like Scottie, who stole my bike by the way, also have a speed with high mount undies except stock and they get quite warm. My daughter wonít ride on back in fear of burning legs. The heat shield is the way to go in carbon. Wonít get hot. The black widow system is about $1500. Thatís a grip of cash. Go for a medium high pipe. They look pretty smart. My previous RS had one from two bros in carbon fiber. Load as all get up.
