No Crossover Tubes
« on: October 27, 2009, 06:27:18 PM »
I have a set of headpipes that have had the crossover tube connectors removed and welded over. I was thinking of installing them and wondered if anyone has any comments, yes or no, about doing this. Any benefits, drawbacks, performance issues, etc.?

From what I can remember, the crossover tubes helped the mid-range power band .

Don't know in reality, if you would notice a difference or not in the performance level of an R65 or not if the tubes weren't there .

I'm pretty sure the bike will run stronger with the crossover.

They even added a second crossover in '81 for additional boost.

I've been running my LS 2 into 2 without any balance pipes for about 20 years.
I've never felt the need to weld them back in, it runs fine as it is with it's custom made mufflers.

bruce, the difference in your muffler backpressure might be helping you.  Every case I've read about when someone removed the crossover from an otherwise stock exhaust system performance suffered.
