My truck is completely stock except for gauges. I have been searching for exhaust for awhile now but i still have one question. Does it really matter if you run 5 inches on a truck that doesnt have any modifications. they say that 5 inches should really only be used if you are putting out more than 450 hp but i was just wondring how much of a difference ot really made. Right now im stuck between either getting the Silverline T409 4 inch turbo back or the ShopDiesel 5 inche straight pipe. Thank you for all input.

shoot Smarty alone has put stock trucks to 460's hp...and 5" is cheap.
I say 5" but I am sure others will say different.....

4-inch should be plenty. Just replace your stock muff with a nice straight-through model.

I have a 4" but why not get 5 ya know?

Hicksy

Would there be any drawbacks of goin to a 5 inch straight pipe with just stock horsepower?

you "may" notice a very small low end lose...but if you add any chip, module or programmer it will be gone...least that is how it was on my truck..

Hicksy

Thanks *****'s. I think i probably go ahead and get the Silverline as i will not be doing any other modifications other than intake. Engine mods will come later down the road.

Thanks,

When the trucks were 3 inch everyone needed 4 and now that 4 is stock we need 5 why not just go 6 and be first in line . My feelings are 4 is enough even for a truck with mild modes and the gain if any would not be worth the trouble .

I have a 4'' but sometimes I would like a 5.'' But knowing me if I had a 5'' I would say that I sometimes want a 4.''

I did the 4" w/ straight through muffler and it sucked. The drone that is, I thought my teeth were going to crack from it. I changed to and Aeroturbine and it went away AND was actually a bit quieter with faster spooling.

4"=raspy tone
5"=deep tone

4" will support well over 450hp, you dont NEED 5" until much higher hp numbers. The only reason I went from a 4" straight to 5" straight was to get a deeper, better tone and it was worth the money. For 295 shipped to the door why not go with 5" when it sounds so much better.

Hicksy

Has anyone tried the ShopDiesel 5 inch? if it has a deeper tone than 4 inch ill go with that because it is way cheaper

I think thats what mine is, I may not have gotten it from shopdiesel but it is the same kit. I am pretty sure they are all (the cheap 5" bolt to gether kits) made by expandit.

Hicksy

Wap, has yours handled rust ok. i just dont want to get an aluminized system and have it rust badly in the first few years. How long will the aluminized last?
