I just installed my new arrow 2in1 system on my 07 bonneville. I thought the sound was awesome but not quite as loud as I'd hoped for. I decided to remove the baffle which comes out simply by knocking off a spot welded tab and pulling out a fitting ring. With the baffle removed it is LOUD! Too loud for my neighbors even in my garage with the door closed. So the baffle has been put back in for now.

So now I am wondering if I could create the volume I'm looking for by modifying the baffle? It's pretty much a plugged pipe on one end with some holes drilled on the sides so I am considering trying to drill more holes first and eventually, if needed, chopping the end off.

Does this sound like a horrible idea? Does anyone think that this would make a difference? If it makes it sound crummy I would have to just leave it out and upset the neighbors anyway. I'm also a bit uneasy about experimenting on a $1100 piece of equipment. I haven't jetted my carbs for the new exhaust yet, so I'm also wondering if pipes usually sound any different after you do.

Thanks!

Haven't seen anyone do this this to a higher $$ system, but is is very common for modifying the stock mufflers. I recently did it to my stockers with good results. The stock baffle on mine was basically a 2" stub pipe thru a steel disc(the baffle) that had two small, maybe 1/4" holes in it. I drilled three 1/2" holes into it to open it up. I like the results, alot.

It might be easier to experiment by drilling a hole into the end or cutting the end off versus the sides as this might be easier to weld/repair if it didn't work out like you wanted.

Sound after rejet? I don't know as mine is still stock.

Thanks 62rag. I like your starting with the end idea.

And to mikeinva. I hear the d&d's are pretty loud too. I'm from Richmond, VA. People there are use to rednecks rippin around on loud bikes and cars with boomin bass. I live in Portland, OR now. It's a little different out here. Everyone is all PC and whatnot. I do miss the lack of rain in VA.

thats all its been doing here is rain lately. The D&DS are not that bad unless you get on it .I dont think there as load as preds where on my bike. You can just unscrew the baffle bolts and take it out on them and repack it if you want to change the sound.

The dd's definitely aren't as loud as the dominator sports/predators. I have heard that the dd 2/2s are louder though.

Here it is SCCTrim. Sorry the pic is so small. I just got a Mac and haven't figured it all out yet. It had ten holes in it and I just added five more. Hopefully that will make a difference.

The pic is plenty large..the good thing about that baffle is there is plenty of room to add hole's. Just don't add too many in one shot.

What is the inside&outside dia of that long part of the baffle
