exhaust*?

[onealmx11]

I installed a 5" turbo back exhaust (silverline) and cold air intake (volant, with ram air). Took to exhaust shop to have welded together, to prevent slipping. He told me I was ruining my truck with that exhaust. Is 5 in. A bad idea? Am i losing any power, torque or Mogadishu by going with 5 in.?

That's rediculious. A lot of people on here run 5 and 4in exhausts. Including myself. These trucks need to breath! But

I have a little advice for you.... Don't let that guy ever touch your truck again. Obviously he doesn't know what he is talking about. There are plenty of guys who run 5 inch exhaust. There is no performance gain over 4 inch but who cares, it sounds and looks better. Anything is better than the stock exhaust with its stupid muffler and catalytic converter. Let that truck breathe

Kinda what I thought. That was the reason for the purchase. He wouldn't work on it anyways. Prob cause I pulled cat. Converter . I know no gains over 4 in., but ant losses due to 5 inch? Just curious . Gonna leave. Like u said, looks and sounds bad ***. just have to fix, down pipe rubs firewall . Anybody else have that issue?

Definitely no losses due to 5 inch. Some say that you lose a little bottom end when you move up to the 4 in downpipe from the stock one, but idk, and who cares anyway. you don't need bottom end when you're going fast

Uhhh... you bought a "ram air" for a forced induction motor? I digress, 4" is fine, 5" flows the same but sounds different. Muffler guy is an idiot.

Well, I bought the intake, ram air is an optional top for the intake box. I didn't know it came that way. But why send back, ya know.

yeah, muffler boy don't know what he is talkin bout, have heard that with the 5 you will loose some off the line till you do major mods.

5" doesn't have you lose anything off the line. There is a minuet difference between 3.5" and 4" DP's, but I've seen nothing on the 5" exhaust systems loosing power. My 5" system flows very well, with plenty of throat.

As mentioned above, don't have this individual (or shop for that matter) touch your truck. They don't know anything about these trucks.

Depending on how the intake is formed, the Ram-air side of it allows for air to be drawn from another location in the engine bay. Typically a cooler location than stock.
