my lonesome have been working on a set of mufflers that don't sound like fecal matter. I am having a difficult time finding just the mufflers (race mufflers). I DO NOT want an entire exhaust system. I do have the capability of fabing up mufflers, I have custom made equal length headers to an x pipe thus far. I DO NOT want the mufflers to have those two little connections keeping them together. I will be making this a side exit. The motor is a carbed 5.5 lt small journal sbc. Should be able to make power to 7800 or so rpm. I am looking for the highest frequency/note/tone/pitch I can get. I very much enjoy the higher, crisper, cleaner sound the euroapean v8 makes. I hate with a passion the rumble of the harley/dumptruck American v8. I have heard flowmasters on these cars. I don't know if it was the particular flowmaster series or what. But that m3 was a dumptruck. I am trying to avoid that. Sounds like a chevy small block doing a dyno pull to me... htt p: //w ww.youtu be. com/watch?v=Y-mGGf5Ncx8 h ttp://ww w.yout ube. com/watch?v=5BhxWH9Dg_M]BMW E92 M3 Eisenmann race exhaust - YouTube[/url] amazing high frequency sound htt p://w ww.youtube.co m/watch?v=SbT0IqFIfnc]iPE Innotech E92 M3 Evolution Valvetronic Exhaust System F1 Sound - YouTub h ttp://www.y outube.com/watch?v=n_n8HiJzA6A]BMW M3 iPe Valvetronic Exhaust Sound (Drive By, Downshift, Rev) - You Tube Here is a cutaway of a corsa muffler. ht tp://s805.b eta.photobucket.co m/user/Phastek/media/March%202010%20Show/Corsa1.jpg.html?filters[term]=recent&filters[primary] =images I am rather sure that the chambers in the muffler can be designed as such to reflect frequencies to cancel out the unwanted frequencies. I just can't find the math anywhere to determine the dimensions of the chambers. I am working with 17.9 inch long primary tubes that are 1 and 5/8 in diameter, they go into a 2.5 inch collector, that then goes into a 3 inch x pipe, that will then go directly to the side exit mufflers. I am keeping it as short as possible to help retain the sound I am after. This is what I am avoiding. htt p://ww w.youtube.c om/watch?v=klmAQFh1l-E]Magnaflow Exhaust on a Chevy Truck - YouTube Same motor different car different mufflers... http://w ww.youtube.com/watch?v=IVWZMKMmjMQ So does anyone know how to design the muffler to achieve this? Or designing a resonator to do this? Or simply the chambers inside the muffler to do this? I am so stuck. Also I don't think a helmholts resonator of any kind will do the trick. that would only cancel out the freq. I think this is more like a musical instrument where the sound entering is not going to be the sound at the bell of the horn coming out.
