I feel like this is a bit of a wacky inquiry, but here goes... New project is a slightly rodded out '53 chevy with a 350 (bored, mild cam, headers, etc). 3" exhaust and it does have mufflers but its still loud and gnarly. In a good way. I like it and think it has a great sound for what the car is. I live in a peaceful neighborhood. I have retirees and young families with babies surrounding me. I have a baby and a toddler too. I have good relationships with them and we all try to be respectful of each other. So I don't want to be that guy if I can avoid it. Anyone have ideas to temporarily silence the exhaust, mainly for cold starts, tuning and tinkering - anything where I might be stomping on the gas? Just something that could slip on/bolt on/get put around, etc and then removed before driving away? (car will live on the street mostly, so garage isnt always an option) Looking around the good ol' interweb turned up responses like "f*ck your neighbors" on mustang forums, and "if you want a quiet car get a Priass". Basically you're an a*shole for wanting to be respectful and still have an aggressive sounding car. I saw some videos where guys shoved pool noodles in their tailpipe (hah, not to be taken out of context) but no thanks. Anyone see a reason why I couldn't get some quiet mufflers and fashion a gasket type connection to the exhaust and run through those before departure? Or a muffler that has an end that can be inserted into the 3" pipes? I'm fine with some noise, it is what it is. I'm just trying to find an ideal situation.
