Un-muffled 6.2

[SouthernSteel]

m1008 with a 6.2 straight Piped Diesel is LOUD especially routed up behind the cab not sure what u consider loud but i consider this loud but to each thier own

i live on a country road heavily traved by motorcycles ,atvs and a bunch of younger guys all running un muffled diesels.the diesels make the least noise of the bunch.maybey its the 3 inch stacks through the bed that makes them seem not so noisey.since its legal in pa not to run mufflers on a diesel a lot dont.its their personal choice and being older i still think they sound good when they go by.

I want to add , most people that might be thinking about a straight piped diesel also need to remember that 99.9% of the diesels on the road have turbos. The 6.2L is naturally aspirated so it doesn't get the muffling effect via turbo. Just 6.2L's of high compression diesel engine. If I remember correct the stock muffler is 2.5" in and 2" out. Wonder if they need a bit of back pressure? I noticed zero power gain and just a very loud dirty sound.

Ive seen test even with headers the 6.2 dont make but 5 hp more and only 1 company makes headers for the 6.2.I hope to add a turbo to mine someday.

And it's actually converting thermal energy into kinetic energy

Thermal energy is kinetic energy

Do you have a link to that test? I am curious about what HP and TQ that headers make on the 6.2

Yeah save your money for the 200hp ones.

When did you start selling the 200hp injectors?

I have a few kits left. 40hp, 200, and the bad boy 400hp injectors. I take paypall and unfortunately they are absolutely no refunds because of such big gains in hp.

We should combine forces on this venture - I've been developing a new head for the 6.X engines - 4 cylinders per valve, with double-acting crumpet gudgeon springs, and an O-pipe from KaleCoAuto... O Pipe (Dual Exhaust) - $125.00 : KaleCoAuto.com, Your home for the rare, unusual, and hard to find auto parts.

I ran mine w/o mufflers for a while turned out in front of the rear wheels. I also added 2.5" O/D by 1" I/D washers inside the pipe. Sounded great at idle, but was to loud when revved. It sounds like a drag car doing 110, but your only doing 30. It's alright in the winter, when the windows are up. Summer time is just awful and embarrassing. I ended up with a new exhaust system. No noticeable power gains at all.

All motors are just air pumps, you can force more air and fuel into them and realize some more power, but even that increases the wear and heat. If you are running a turbo, you can gain some more power by thermally insulating the exhaust and housing to force the heat down the pipe instead through the sides of the pipe and housing. I used HPC Ceramic Coatings and increased my boost 2 to 3 lbs all the the turbos map range.
