Brutale Exhaust!

I have a 2009 Brutale 1078 and I want to pull the mufflers off right behind the cross over pipe. I have been told with out the back pressure of my pipes it will hurt my engine. Has anyone heard of this to be true?
Thanks.

You probably mean the mid pipe since the cross over pipes are between the header pipes at the front of the engine.

I don't think it is true. It may not run as well and it will certainly be loud.

Why would you want to remove the mufflers? Unless you have a new system to install.

Yeah, it will run like crap and draw the ire of your neighbors, police and politicians.

I used to be fast....now I just dream about it.

If I have understood your question - Make it more free flowing and it will typically run leaner with the original mapping - something that drastic (no mufflers) will almost certainly require re-mapping - Power commander etc. Try it .... you well may lose tickover so that will warn you - that is if you can still hear after removing them

I live in the mountains so Im not worried about the noise. I do know that it will hurt the performance. I was more wondering if it will hurt the engine? such as lock of back pressure or running lean?

It will run like crap if you do not install a race ecu and a pc5 or a microtec,your fueling will be out and not good for the engine.then you will have to put it on a dyno to give it a chance to run correctly.Are what the hell is the worst that can happen ,maybe a new engine ?.there cheap on ebay?

good luck cheers.

If you search for mid-pipe in the forum you'll find quite a few examples of guys who have removed them and added a microtec / PC for correct mapping. I haven't hear of any issues impacting the engine.

I believe he is talking about removing the cans in their entirety cruiser. That is taking the cans off and running with headers and midpipe/cat only. Interesting
