Well after a month or so of hassle I was finally able to get my straight pipe on and man does it sound awesome. I will see what I can do about getting a sound clip up within the next couple of days for others to hear that are debating on whether or not to do it. I don't think my neighbors are going to like me too much anymore though

 

How big of Straight Pipe and is it on the stock downpipe?

 

Its just the stock 3 inch pipe with the same down pipe...would it be possible to have a 4 inch down pipe with the rest of the piping being 3 inch? would that be benificial at all?
I just took a sawzawl to the restrictive devices and bought 5 feet of 3 inch pipe, had each end opened up enough to go over the 3 inch pipe and welded it back together. Took me about an hour and a half or so to do it all.

 

??????

Just a bit curious about this - seems all my pipe from the bottom of the down pipe to the resignator, to the muffler and on out the back was all 4" pipe. When I had both my resignator and muffler pulled, they took a stock piece of 4" and welded everything back together. Did they use 3" on the earlier trucks? I thought it was all the same....


Later on, about 8 months later I added my stacks - 4" all the way from the back of the turbo....

 

I am not sure what size pip was on your truck but my pipe was definetly 3 inch from before the cat all the way to the back. Not sure what size my down pipe is but im gonna guess that it is 3 inch too.

 

i have 4" pipe from my turbo all the way to the back with a 5" tip, it sounds nasty, my neighbors hate me, and my dad thinks my truck is way too obnoxious...but i kinda like it that way!

 

I dont think there would be any benefits to running a 4" DP to a 3" system, I just didnt know if you put a 4" system on or a 3". So you do like the sound of the 3" then? I was going to wait til I could afford some 4 or even 5" pipe to straight pipe it because I heard the 3" straight can be raspy. But you say it sounds ok. Thats good to hear, mabye I will be straight piping earlier than I thought.
And dont quote me on this but arent the stock DPs a 2 9/16" opening to a 3"? I am not sure, someone buzz in that knows what they are talking about.

Thanks

straight piped factory exhaust sounds sweet!!!!

 

I agree,they do.But when you get a 4in. it is a little deeper and smoother than a factory straight pipe.

 

and 5" is even deeper and meaner!

but no reason not to straight pipe the factory setup in the mean time

 

you got that right...

 

Aw,come on guys.your makin' me feel bad.I cant fit a 5in past the t-case!

 

so run it after the xfer case!

Forrest is right-on


any straight pipe is better than no straight pipe

4 inch is no prob past the t-case....a little tight, but adequate, then open her up to 5. I liked the tone alot better with 5 over the 3, which I started out with. Noise level is the same, but the rasp is all but gone. That's all subjective to what you consider raspy. I think most will agree that straight 3 is quite obnoxious when reaching into the coal bucket. 5 mellows it out ALOT. Now I DO have the crossbox design as of now, which I know will change it some as well. In the not so distant future I will be changing over to all tight radius mandrel 90's and eliminating the box.
