ok so this summer I'm thinking about making my car a bit more "invisible" for lack of better words, flat black, other stuff, and a new exhaust. currently i have stock exhaust, with a coffee can aerotec muffler on it, sounds great, just loud... so what specifically should i do to make it really quiet, with out hurting performance. i was thinking replacing part of my exhaust with a cherry bomb, and putting the stock muffler back on, so a grand total of 4 mufflers, i heard something about resonators, i really don't know a lot about the terms, i no it makes things quieter, and that a resonator is a kind of muffler, (absorption).

so any ideas?

Yea... I wanna hear your comments too.. Im so interested at this. PLEEEEEEAAAAAASSSSSSSSEEEEEEE
What do you guys think the best set up would be?

The muffler does exactly what its name implies. Muffles... so if you put on a "performance" muffler, it will be louder. If you want it quiet... put on a "muffler" that muffles. =D

yes, i know that, umm, i guess what i am looking for is if there is a brand that would be better than another for being quiet.

HKS Hi power silent exhaust.. but its woth 600$. Willing to spend that much? Not me right now.

your best bet would be a full 2.5 inch exhaust with a long magnaflow resignator and a magnaflow muffler...extreamily quiet but when you do really get on it it has a low deep rumble to it but it's not loud by any means....magnaflow FTW

alright, thats what i was looking for, thanks

how much would that cost total?

Actually, a resonator is not an absorption-type muffler, it just looks like a narrow-body straight-through muffler from the outside.

A resonator, well, resonates. It's an echo chamber, bounces soundwaves off each other so as to use sound cancellation. Resonators are great at smoothing the exhaust note, and good at reducing the volume.

A straight-through muffler uses sound absorption -- it's a perforated pipe wrapped in insulation. Cheap ones such as Cherrybomb use fibreglass. Quality brands such as MagnaFlow use a ceramic insulation with stainless steel wool. Straight-through mufflers are great at volume reduction without notably affecting the exhaust flow (longer muffler = less volume), and do smooth the note somewhat.

One further point on Cherrybomb -- it's 1950s technology. The central pipe is louvered rather than perforated, so you have dozens of little scoops intruding into the exhaust stream. Theoretically they improve the sound reduction by directing the exhaust flow into the insulation and thus increasing absorption. Trouble is, this creates massive turbulence and severely reduces the efficiency of the exhaust system. Plus the fibreglass is prone to breaking down and blowing out.

ok wow i did know the differance between mufflers, i just was in a rush, and am bad at proof reading.
-cherry bomb, yeah i was actually thinking about just making my own but with steel wool, and drilling about a thousand odd holes... heh... one of those long nights with the guys and 3 power drills in my garage....

thanks again for your help
