View Full Version : 2001 Sportster 883 exhaust crossover pipe question

The scenario... bought my first HD Sportster 883 (hell, first HD) a month ago, and began chopping, sawing, modding, etc...

I am installing a Joker Machine breather to give more leg room, get more air in, and show off more of the engine. Then I realized the exhaust crossover pipe also covers up quite a bit of engine horizontally, so I figure will just build my own pipes. Here's the rub.... just about every bit of information I find on the factory pipes is that crossover pipe makes the engine more powerful/stronger. Any truth to that? Do I really need a crossover pipe on the 2001 Sportster to get the most out of the engine?

I want to clean up the look by removing the need for the crossover pipe. Any advice/suggestions?

It's not that big of a loss. Cut it out and weld it up

I prefer my stock head pipes with slip ons over the drag pipes I had. Went from stock to drag pipes for all of 2 weeks and switched right back because of less seat of the pants power.

Not a big deal to cut out that crossover. You will lose some scavenging pulses at a very specific rpm.
A stepped two into one with a nice merge will give you "the most" . Make or acquire one. A poor flowing exhaust may feel ok down low but will loose in the top end.
Of course, pipe sizes and length between the steps and/or length till the merge are all important. Specifics of your motor build/mods should be part of your calculations.

did it on my 99 as the pipe looks shit.
my pipes were made shit the crossover stuck into the headers just over 1/2" so all thats going to is restrict flow.
the bike seems to be a bit smoother on the throttle off idle picking up a bit quicker. could just be wishful thinking tho but i prefer it.
