Does gutted out stock exhaust require TPS reset?

[brijesh600]

I recently purchased my 2003 XB9S, the previous owner swapped his stock exhaust with a completely gutted out stock exhaust, so that is what i have. the bike seems to run a little rough and pops a lot when i decelarate or slow down. I am wondering if i should do a TPS reset on it to solve the problem, or just wait and ride it that way till i get my drummer exhaust in!
I checked with the previous owner if he did a TPS reset when he put the gutted exhaust on, and he said that for a gutted exhaust, TPS reset will not be necesary.any insight on this?

depends on when you are getting the drummer.

normally it's not needed when the stock pipe is not needed, but since your bike is running rough, i would do it, unless you're getting a drummer next week. ;)

Kevin from KDfab should be receving my stock exhaust today, so i am guessing another 2 weeks atleast before i get it back, and i have a few good days coming up for some riding, but i dont want to harm the engine if that is what the gutted exhaust is doing to it![confused]

you'll be ok for 2 weeks, it just won't run as smooth as it could.

ok, i took the bait and bough me a race ECM from iron machine too! Cant wait for the drummer to arrive so that i can do the TPS reset and get that bike to feeling better!

The short answer is: The previous owner is correct, but for different reasons. An exhaust modification does not require a TPS reset. Period. Doesn't matter if it's a Drummer, gutted exhaust, Micron, or any other exhaust. The TPS has nothing to do with exhaust mods. A lot of guys do it anyways, just to make sure everything is optimal, but once you do a proper TPS reset, you should only need to do it again if you change the ECM, throttle body, or need to correct a improper TPS procedure (or worn TPS).

Thanks for that very useful information!
