Flexible exhaust tubing for shop/garage use

In yet another effort to get my one particularily overzealous neighbor off my back, I'd like to get some kind of freshly chopped off stock mufflers from a muffler shop, and hook that up to my tail pipes when I'm tuning at home in the garage. In order to do that I need some kind of tubing that I can quickly clamp onto the my 3" tail pipes and onto the likely much smaller stock style mufflers. I suspected that just aluminum flexible tubing will not do much to make sure the noise makes it all the way into the mufflers, and I think I've seen dyno room stuff that seems to be insulated or something. Just looking for something that will work, so that I can work on the car tuning without any reason for anyone to get pissy with me.

I will also appreciate any alternative suggestions on how to tune at home in acceptable silence. For comparisons sake, I runn full 3" through Ultra flows and tails, then I have been hanking the 3" version o fthe super turbos off the tail pipes and still getting complains. Partially I think the neighborood has no trees or obstructions to eat sound, seconly they point at a 45 towards my driveway which probably doesn't help evac the sounds from the neighborhood. It is current quieter than a lawnmower 1/2 block away, but still not good enough for that one neighbor and supposedly a few quiet ones that haven't told me.

Strange thought, but do they have those vent pipes installed in the shops up there so they don't have to work with the doors open? Maybe a shop is closing and you could pick one up cheap....might work to direct the sound even with the door open...

Actually I'll do that when I phone around looking for some free old OEM mufflers to steal. I also noticed that my local gregg distributors list this stuff, so I'll phone and find out what it'd cost me for a chunk of this hose. It's 600F/315C rubber hose. If it's cheap enough new I'll snag a chuck of it.

first thought, if it's pointing towards your driveway, then yeah it'll be a lot louder than if it's straight out (or up).

if your system is complete right now, I'd probably get one of these

3" rubber exhaust hose and cut it in half, or 2 of them, and then stick the dynomaxes on the end of them for tuning. you could maybe even mount them on a couple of stands so they point straight up instead of out or down.
