Hey guys. Just joined the site. I took a 1/2 inch drill bit to the exhaust last night, WAY better sound than stock! Thank you for the videos and instruction. I was wondering if anyone has went into the middle baffle with eight holes? I know this would be pretty tricky to do and just curious if anyone has done it. I have been waiting for my 3inch hard kromes for 3 months now and if I can get a little more out of the stock pipes then I will cancel the Hard Kromes.
