Is there a way to drill out the baffles or to some way make the stock F4 exhaust a little louder. I really don't want to spend the $400 for a pipe. Just wondering.

 

Not sure how the tip is attached on a stock f4 exhaust, but my friend had his girls GSXR 600 exhaust cut down to a shorty and reattached the tip. It sounds good and looks sweet. I would do the same to mine, but I have a D&D and it's loud as all hell already.

 

If you wanted to cut down the factory exhaust you would have to re weld the top back on.. I do not suggest taking out the baffle or packing due to back pressure issues.. I would cut it down if anything.

 

Drill a crap load of holes in it, that will make it louder.

Seriously tho, I have thought about cutting my stock exhaust as well. If I had access to a welder I would. But as is I would be better off just buying a used pipe.
