Bonneville America Forums Forums Technical Forums Exhaust Can I add aftermarket pipes without rejetting?

Hi, I have had my 2006 Speedmaster for about 8 months now and would like to change out pipes for more sound. I am not interested in a power increase, just a sound increase so cars on our lovely Southern California freeways can hear me coming. I don't want to have to rejet if I don't have to. Are there any aftermarket pipes that are reasonably priced that I can put on without rejetting? Thanks in advance for your advice.

tors dont need rejetting, but there have been a lot of people who still bought new pipes, thunderbikes are a lil pricey, dont need jetting, but you will feel a very nice difference if you do. i say spend the extra money on a better pipe than the tors, jetting is cheap and easy if you follow pats destructions and you will feel good about it when your done

you can put any pipe on you want & not rejet. the worse thing that is going to happen is it will run like crap & then burn a hole in your piston

I've done that! After rebuilding the carbs on a 650, I put them back on and forgot to torque one of the carbs to the intake causing it to suck extra air. At 110 mph, started cutting out and running on one cylinder. I looked back and saw a glowing red spotlight through a cloud of blue smoke. The CHP did not give me a ticket, saying "You'll spend enough on your new piston to learn your lesson".

Yota,
"run like crap & then burn a hole in your piston "

you have such a way with words.....

Some pipes need rejetting, some don't. Triumph offroad pipes don't, but you might not like the sound, Thunderbike make some that don't and they sound nice.
Even if you get aftermarket pipes that don't have to have different jets installed, you will probably get better power if you rejet anyway because these bikes are setup at the factory as lean as possible, maybe a bit leaner, to make the government people happy.

being that i live in fl. i am probably at a similer sea leavel as you. i put the Septres on my bike and have not rejetted, i know i probably should for maybe a couple more ponies?? but i havnt. i am not running to lean, she is a little lean but she comes that way stock, my plugs have looked very good each time i inspect them and that is about all i can go by. but i have been runnug her that way since before she was broke in all the way, so that is pretty much all she has known for exhust hahahahahahaha i talked with Todd after running them on the bike for a few months, told him what the plugs looked like and the increase in power she seemed to have and he felt like i did that because of the sea level air, i probably was ok. 5 yrs later and all is well.

Buy the straight pipes that are in the classifieds, add some baffles from JPCycles if they are too loud. It is a inexpensive way to get a change and it would look good.
