I bought 10 feet of 4 inch pipe for my 1993 w250
..I cut off the old muffler and I want to add this pipe to it and have it coming out on an angle
Question-Can I cut the pipe on an angle then weld in again to have it coming out sideways or will it make it weak and make the flow bad ? ... i think it will work but just checking ! thanks

 

you can cut it an weld it as far as strength it shouldnt really matter unless your pullin a house down . just make sure to have some hangers holdin it up i broke my downpipe by not havin any

 

Diamond Eye makes a nice 4" turbo back kit for these trucks, and Alligator Performance sells it for $300 give or take. I put mine on in a few hours, and it was well worth the $ in my opinion. Sure you can miter cut and weld your exhaust, but in the end it looks like someone miter cut and welded their exhaust together. An exhaust like that wont flow as well as a nicely bent one, but you probably wont really notice it.

 

The diamond eye kit for a 1st gen 4x4 is $269 shipped. that's a straight pipe, the muffled version is $309 shipped. I just avoided all the hassle and put the exhaust through the hood. sorry about all the clutter in the background, Parted a ferd and haven't had time to move the stuff around.

 

Sweet hood stack man!! Isn't the original exhaust 3 inches? Is there an adapter that converts it to a 4 inch on the downpipe? Sorry to hijack the thread.

 

You can buy An adapter, the diamond eye system includes a down pipe.It's 4" turbo back.

 

yes there is ... I made one !!!! or you can buy a fitting for 50 bucks or so ... i made a converter from a piece of pipe though !

 

269 from tvdiesel.com includes downpipe its all 4" straight no need for adaptor

 

Is there much of a difference in a 3 inch straight pipe and a 4 inch?

 

yea , the stock pipe on my truck is 3 inch and when you look at 3 and 4 beside each other it is a big difference....as far as performance and sound goes i have no idea....but ill post some pictures of my truck with the new headache rack and pipe later !
