i just used a hole saw and drilled the baffles out of my stock exhaust. i pulled out all the fiberglass and have put on probably 6 miles. its loud as all hell, and damn near annoying, i was just wondering if its safe to run it like this till i can get some cash scraped up to put on actual exhaust? sorry to enter a new thread that is the same as so many before, but i can't seem to figure out the search function. oh, by the way, i have a stock air intake, and no tuner. thanks in advance.

ok, i just wanted to make sure i wasn't going to burn up any valves running with out much back pressure. thanks for the nod on steel baffles, i might just look into that.
I beg to differ. You may cause damage and you ought to at least check you spark plugs for a while to make sure you are not running too lean. I know that people say the stock ECM can make adjustments, I know people say that the A/C is restrictive and won't flow enough air -- but those people are not going to pay if there is trouble. The air flow can and will change (at least slightly) do to freer exhaust. Check to be safe and not sorry.

So you drilled out the baffles and removed all the packing and it's annoying huh? Imagine that
I understand it won't hurt your bike, just everyone who has to listen to it.

Every one that I know that has done this has been sorry afterwards..
People just don't believe how lousy they will sound. Plus mess up a set of stock pipes..
Keep an eye on Ur plugs that they aren't too lean.
The rule of thumb is pipes only change, needs no other work.
But U probably lost some bottom end by doing away with Ur backpressure..
