In an effort to give my bike a little more rumble I'm removing the cats. This is just until I have the funds to get complete new exhaust. Has anyone else done this yet?

OK, so I modified a set completely, including drilling out the rest of the mufflers. Video below.It actually made quite a difference at idle, the exhaust pulses are a lot more distinguishable. Off idle tho still whisper quiet. The next logical thing to do is to insert a long drill into the end and drill a hole. Starting small of course and increasing as you want more noise. I'm hesitant though, it will be irreversible and my luck I would develop a whistle and sound like tweety bird flying down the highway.
My pleasure. Cost will be quite affordable with exchange.Thanks for doing this Todd. This is a great service you are offering and will allow many Cali owners to get a better sound without the ridiculous cost of aftermarket Italian mufflers.
I didn't run them without drilling through the baffle plate, but I'd imagine it will still be quite quiet even with the cat-cons gone. Let me know if you'd like to do a set. You can bring the bike out to the shop, just need to schedule the time in on my end.This is interesting. I'm sure things are a little cooler with the cat removal. I might be interested in the cat removal but leaving some baffling in without drilling straight through. A little more flow, less heat while retaining the mellower tone.
Per above, the mufflers must be cut apart, drill out the welds on the baffle plate, and welded back together.I might even try to DIY this one if it's not too complicated.
I would presume the cats are wedged in pretty tight in the mufflers?

I'll be digging into set of these to possibly offer up for sale. I'll show them apart and what to modify.
FYI, it is a absolute waste of time removing the cats for more noise as it does very little, if anything, in that department. But, remove the cat, the baffle behind it, and them drill the rear like Todd did and it is freaking awesome!! I highly recommend sending your mufflers to Todd for this, it is worth it if you want what I call the perfect sound.
