Is is it a 2.5" exhaust or 3" because everywhere I went I was quoted an extra $100 for 3" mb stainless. And I looked high and low for 3" stainless and nobody had them, all had 2.5 with the exception of 3" aluminum. So if you have a 2.5 sys, then it would have cost you an extra $100 to go up to 3 "

 

i went 2.5" which is probably too big, why go 3"? Thats a total of 6", only extremely high HP diesels even go 6"

 

Markus,

Two 3" pipes is not a total of 6". The area of a circle is Pi * r^2.

So 3.14*(1.5^2)*2 = 14.13 sq inches

3.14*(3^2) = 28.26 sq inches

You would need four 3" exhaust pipes to equal one 6" pipe.

3" may be too big for a stock motor, but I don't know if it would hurt performance.

 

Found it interesting that if you do a google search on that number (866-862-6690) it comes back to a dozen different websites run by http://on-lineperformancegroup.com/aboutus.html and the toll free number for the city of Mott ND

Good, I love to here about companies going beyond their responcibilities to make a customer happy. Even if they lose money on your sale, they have still made a good investment because people like me hear about it and want to order parts from them. (not that I want exhaust, I was just saying).

 

Good job on that one.

Also, too large of an exhaust can create a loss in backpressure or something like that. It's been dyno proven that too large of an exhaust can decrease performance.

 

With all due respect, my point was the cost to bend mandrel tubing and whether or not what I bought was a reasonable price compared to yours and not to say which was better. Flow starts in the heads, through the headers, y pipe, muffler (for back pressure and sound), then tubing (for back pressure and tone, not hp). If you have the right combo from the headers to the muffler, there will be no hp or back pressure difference between 3" and 2.5" tubing. So if you don't change out the y pipe, there's little hp gain, and 3" tubing doesn't give me any more or less hp gains than 2.5's . But the 3" will give me more of a bellowing sound than the 2.5's, and that's what I want . When speaking of back pressure, even with a high flow muffler you're restricted enough at that funky 2 into 1 connection in front of the muffler, lol. And if the muffler is too loud for me say 7 on a 10 scale, then I'll change it out to one with a 5 on a 10 or less. Not to mention, 8 mths down the road when my truck is paid off, I can install my new Gary Stanton 600 hp+ 426 stroker motor in hopes that the 3's are big enough. Who knows, maybe I'll change my mind by then, but that's my intentions for now.

And unlike fasthemis, AFE said they do not debit my account until the order is shipped which will be around Thursday next week

 

I've never heard of it being done differently than that. besides ebay

 

Did I read this right?? That motor is going in your Ram???
