View Full Version : Would you... (exhaust related)

Next weekend I'm supposed to go on a trip around the mitten if the weather is nice. My question to everyone is:

Would you a couple days before the trip get a custom exhaust straight pipe made?

The reason I ask is I hate my stock exhaust (love the way it sounds gutted) and I really want a new exhaust, I was thinking of getting a V&H short shots but then I thought well for nearly the same price I can get a custom exhaust done by a friend.

I'm just worried about running issues and loudness really.

Just curious to hear your thoughts.

Matt,
I'd wait until you got home man and I'd for sure do a simple rejet after the pipes. On the straight pipes I built I had removable baffles. With the baffles in the pipe ran crappy because it was jetted for straight pipes. Not sure how loud they will be on your bike but on mine it was LOUD. Like ear ringing loud on longer rides with a full face helmet on. Everyone thinks my D&D muffler on the FZ1 is "loud" but it's the quietest exhaust I've had in a long time. After you go loud you'll love it for a while and then you'll start to appreciate quiet again. LOL

Bob, yeah I know the sensible thing would be to not get new pipes so I probably won't I just am really dying to get some new pipes!

snofrog: funny video man! For the record though I just am not satisfied with the look of my pipes, if I could keep the sound of them but have a different look that would be the best of both worlds.

good side of the bike:

The pipes don't fit the look i'm after...

Is that a Bell open face? I keep looking at the Stunt but it would look ridiculous on my bike. I don't think the exhaust looks horrible, what about just powder coating it something more subdued?

if you are referring to the silver helmet that one is a daytona, the checkered one is one I found on egay. Those bell helmets are cool I like the liquid gold, you should pickup that stunt helmet! Yeah I thought about that, I just don't like how long the l upper pipe is and how it is so far staggered.

Dont do it before the trip. Could run into jetting issues and such which will taint your riding trip.


Nice lookin bike BTW

I think I've seen you riding around Clarkston. One day last week I saw what looked like your bike and a orange framed bike. Hot on your tail was an Oakland county Sheriff.

If your gonna go with custom pipes, and are worried about noise look into a set removable exaust silencer/baffles.

If your just worried about proper back pressure just have your builder make a set of tuneable baffles.
Either way I'd hold off until after the trip so you you can work any bugs out if they should pop up.

Heres a few links for exaust silencer/baffles :

I used the 3rd ones down but the bike ran like junk with them in. Just know if you tune the bike for straight pipes and you run those baffles that you'll create a TON of back pressure and will be running rich. But it did make it quieter. I was going to smash the baffles down some to make them no so restrictive but just never did and never put them back.

just use the washer trick thingy for back pressure i lost the link i had to it may gas has it i think he has mentioned it here before as well

A fender washer, bolt, and either jbweld or tac weld (prefer the last). You spin it to control the amount of backpressure. So it's a tunable baffle... as in you can adjust to what your bike wants to run correct and produce the most power.

hmm interesting, i'm surprised that little bit of washer creates that much back pressure.

I was too until I saw the inside of my old Hard Kromes. Freaking things are pretty much just straight through but they did offer some back pressure.

Sometimes its as much about breaking up or changing the reversion wave as it is about back pressure. Some have used a straight bolt or even an eyebolt to do about the same, however the fender washer does give more flexibility. Ride safe.

you would be surprised... hell lots of bends and crap give more bp. also, the reason why people went to mandrel bent pipe instead of the old crinkle bends... not only a cosmetic but also a bp thing

I think my FZ has some sort of valve that opens and closes in the exhaust to create back pressure now that I think of it.
