the term slip on is from way back in the day when mufflers did not bolt to the pipes, they were built as one piece. If you wanted an exhaust you could get a full system or a slip on. For the slip on you had to cut off the original exahust, or disconnect it after the collector under the bike, and the aftermarket piece slipped on the existing pipe.

 

I thought slip-ons were mufflers that slipped onto the header pipe and were held on with springs....thats the way my Two Brothers cans are on my bike.....going back a ways, my 85 FZ750 had a Hindle slip on. On the engine, short pipes were bolted to the engine at the exhaust ports, bout 2 inches long. Then my header fitted over these and was held on by four springs at the engine. Then the muffler was pushed onto the end of the header and was also held on by springs and a clamp around the muffler to fasten to the frame...

 

1) The superhawk does not use bolts on its muffler cans. A bike like the SV1000 from Suzuki does, however. The "bolts" are located right where the springs are on your (and my) Two Brothers Exhaust. Instead the VTR aftermarket cans "slip" onto the midpipe provided by your manufacturer. The stock cans (and the associated foot or so of mid-pipe) are removed when you put on an aftermarket system. Many times you will have to use aftermarket exhaust hangers also, due to the new configuration.

2) Stock cans are about as heavy as you get, and in no case will switching to slip-ons increase the weight of the exhaust.

3) It does add noise, and that's probably the number one reason people get aftermarket slip-ons

4) They are fairly expensive, but like any other good mod for the Superhawk, you gotta pay for what you get.

5) Since these pipes typically give increased exhaust airflow, your bike will tend to run more lean than at stock, so you will probably want to re-jet to a richer set of jets. Stock bikes run lean as it is, and richer jets are a good idea, if nothing but to prevent engine damage from running a super-lean mixture. This increased airflow and fuel will translate to extra power (UP TO A POINT because the cylinder can only combust so much).

6) True that. They do look cool. In fact girls often ask to sleep with me just because my exhaust pipes look so shiny.

7) Negligible. And besides, the "clamp" is way under the rear cylinder, completely out of visual range. Remember, your slip-on system usually comes with a mid-pipe.

Pretty much the only difference between a "Slip-on" and "full system" is the replacement of the headers. The full systems allow for better airflow over the stock system, but I think THAT is the overpriced aspect. Full systems are like $1000 versus the slip-ons which retail around $400-700 typically.

This concludes our broadcast day. You stay classy San Diego.

 

Unless you don't care if it's brand new, then keep your eyes on sleezbay. I just bought an Indigo full system for $80, the cans were smashed but the head pipe was good. I didn't care because I just used my 2Bros cf cans instead. Which I also got off ebay for about $150.

 

Gotta agree with you about the 2 Bros pipes....nice deep throaty sound.
Last fall a few of us went out for a ride, friend who came along had a VTR with stock pipes. We stopped at a donut shop and when we came out of the shop, some teens were eyeing our bikes....mine a bright yellow with the 2 bros and undertail and my friend with the stock VTR...They loved it when I revved up my bike, laughed at my friends.....
Another friend ended up changing the stock cans for Scorpio's over the winter and they are pretty nice sounding as well.....

 

Save yourself some money and just do the baffelectomy!!! My pipes kick A$$

 

You must collect exhaust systems.

You had just bought when when you sold me those cans. The do sound sweet even if they don't boost performance.
