Question Should I........?

I have an 05 gsxr 750 with a full micron exhaust and I was wanting to shorten the muffler and gutted it repack it but was wonderng if it would sound crappy and not worth it. If not how would I go about doing it since I don't see any rivits on the muffler.

If you remove packing or go to steel wool could get deeper in tone.

If you shorten the chamber it will definitely get louder.

If there aren't any rivots and the tail section isnt bolted on for repacking you're looking at a cut and weld scenerio.

But will or sound like . And i don't think it's a weld cuz there's no factory weld.. It looks like it's pressed or something

Deeper tones are cool. Loud is what gets annoying

I've seen cans that are sleeved and rivoted on the bottom only; when you take the rivots off, the tip comes off w the inner tube and outer sleeve; then separate via press fit.

If you pull off the slip on and start it up, consider the difference between the can on/off and consider half chop half the noise. Obviously that is basic science and depends on insulation you pack and is only a guideline; could be louder or quieter.

I've shortened many aftermarket cans that are factory at 21 5/8" + in length. I have found that optimal seems to be at the 11-12" length. If you get shorter, they tend to get MUCH louder. If you don't go below 15", not much worth the effort. It seems that the sweet spot is in the 15" - 11" total length on these series mufflers.

I had a micron Exhaust on my R1. It was cut down and shortened and I loved the way it sounded compared to before it was cut.
