Ok dont tear me apart but im thinking of ordering a turbo back straight pipe exhaust, but im DYING to hear it with the cat and muffler removed...for about a week, would it hurt if the stock exhaust was cut out right before the cat and just ran that way until the MBRP gets here? Lol if it will ill just wait but if it won't, ill cut that sucker out in the morning!

 

Cut it out and enjoy the sound! (Or is that what they call "noise"?)

 

Or save the pipe to sell and just unbolt at the cat
and remove the rest.

My 4" turbo back system, MBRP, is "on the truck for delivery". It will be installed today!

 

Haha.

Being dumped right at the front wont cause any issues though?

 

No real issues, I've done it, crappy welding broke at the cab. Ran it that way for a few weeks just louder and seemed a little boggy low end. But this was on a 4 inch not stock. You'll have soot all over underneath your truck though, gets messy fast.

 

I see here are very good reason to just unbolt it
at the cat flange and save the pipe in case you are not
happy about the soot mess and the new pipe is not
getting to you fast enough. Be it money or out of stock.
You can stuff t he old on back in short term.

I may wait then.

will a stock motor with a straight pipe blow black smoke? Or do you need more mods/custom tune to blow black smoke? Lol

 

I went with a bolt on kit as well. Much easier. As long as you get good clamps. Yes stock trucks can blow smoke.

 

ok so im looking at an MBRP 4 or 5" straight pipe system to put on my truck.

from the turbo, is it 3.5" all the way to the back of the truck? so a kit like this, that is 4", does this replace all the 3.5"? im reading through old threads and some say they start from the downpipe, im not sure and would like to clarify before i make a purchase.

few questions:

-the exhaust starts directly after the turbo, right?
-right after the turbo is where the downpipe starts?

these 2 kits i believe are essentially the same, but one has more pipes pieced together, the other has less pieces.

does this kit exit close to where the stock exhaust pipe is located? and i want to be sure i know where on the truck this kit starts (at turbo, right before stock cat, etc)

i think this is similar also, just a 5" version:

thanks for helping!

 

also, i did unbolt right before the cat, just to hear, and i have been driving around with it like that all day today. i love the sound. it does blow a little smoke under the truck, but nothing i can even see from my passenger mirror. i was kinda hoping for it to blow alot of smoke. what would i need to do that (something like this)

custom tune on top of the straight pipe? i've seen some threads on splicing a few wires and making a "smoke switch"?

 

Blowing smoke is a BAD thing. Not only is it bad for your truck it's bad for the diesel community as a whole, not to mention a waste of YOUR money, and it accomplishes nothing performance wise.

 

The only way to make smoke like that is to feed $100 bills in the compressor inlet. But only $100 bills will work. Something to do with the ink they use.

 

Haha. Figured id catch some crap for the blowing smoke comment.

besides that, any input on the other things i posted?

 

Have to give you crap for that. The only time I blow smoke is out my ears when I see someone in their pickup rolling coal, tow mirrors out, sounding like a TF33 jet engine
