custom exhaust
hey all,
I got a custom exhaust put on my truck a month ago. There's a story behind this, but if you want to skip that and just get to the link for the sound clip, that's at the end. :-)
The story started back in May of '05 when I had a dual exhaust put on my '04 Ram Hemi. I liked the louder sound and the better highway gas mileage cost-justified the project pretty quickly. I was driving 50 miles each way to work, 45 of them on the highway. The droning on the highway was annoying but when my sinuses were acting up, my ears would ring for hours after getting to work (and later on, getting home). Since that's a sign of hearing loss, which I didn't want to keep permanently, I had a garage put the old stock exhaust back on.
And then I started scheming and trying to educate myself as to the accoustics accompanying mufflers. I figured that since the original dual exhaust had the muffler right beneath the cab, and since that's where most of the sound wave collisions occurred, it might be less noisy in the cab if the muffler was away from the cab. And since I spent a few hundred bucks already, I really couldn't afford to spend much more (if any) so I needed to reuse the same muffler (from Meineke, "Full Boar" brand, which the guy said is similar to a Flowmaster 40, 3" inlet and 2 2.5" outlets).
I used my sawzall to "accurately" ;-p cut the muffler and tips away from the removed setup, and brought them to the meineke dealer about a year later. (Taken off in Dec '05, put back on in Dec '06). The meineke guy put them back on, this time differently. The old setup had the muffler attached to the y-pipe; this time, it's 3 inches all the way to behind the rear wheel. The muffler is right behind the wheel, and the tips directly welded to that. Because of my "accuracy" problems with my sawzall, they aren't as straight as I would like but other people don't seem to notice.
Since the pipes he put on weren't stainless ($$$), I painted them with rustoleum heat paint, black, with an enamel finish.
The results? Sound is great outside, quieter inside though still some droning on the highway (see my post about sound-proofing with fiberglass insulation), but if I had to guess, I'd say there's not much more power or gas savings compared to stock. I think that last part is because it's the same diameter as stock until almost the very tail-end when it splits into two 2.5" pipes briefly (tips are 3.5"). I'll try to take a pic soon.
Meanwhile, here's the sound clip:
