I understand what you mean by that, and i cant find any...although one wuld imagine you can get the same effect yourself, too bad i suck horribly at illustrating my point. i didnt make a key either... but... um... M is for Muffl0r!
Dang what a huge filesize, i originally made it, and it was too big, i actually had to go back and click 'black and white only' , good thing it didnt have any other colors anyway
I hope this helps, even though im sure it ont, and will most likely boggle and confuse the masses! its late on a school nit bizatches...
P.S. The design is patented by me, now, and will most likely not work, resulting in massive power loss and overheating, maybe if you mounted it like a corvette's exhaust, going to the sides ass aposed to swept back.. ill stop talking now...
