Is it 4"? My old psd was only 3.5", but this looks bigger than my psd. I'm doing my straight pipe and cat delete shortly and was wondering what size to tell the exhaust shop

 

3" When I first got my truck the muffler was rattling so I got a 3" chunk of exhaust with flares on either end and some band clamps. I hated it like that. Bought a 4' and liked it a whole lot better. FYI, there are some sponsors here selling 4" exhausts for a bit over $300 (IIRC)...

 

I'm trying to do this cheap for right now. YOu sure its only 3"? The tail pipe looks HUGE.. closer to 3.5-4".
Someday I'll get a 5" exhaust but for now I just need to fix my exhaust thats broken

 

Measure it - I have not seen your truck personally so its pretty hard for to answer this question. I have no idea if thats a stock exhaust or not. Im telling you what was on there from the factory.

 

It looks stock, has the stock hanger where it exits, has the stock muffler and cat etc I can only imagine its stock. 3" it is! Seems obnoxiously small but easier piping to come by I suppose.

 

mine was 3inch stock

 

open her up and let er breath, expandit is dirt cheap and a hell of a system if you wanna go cheap

 

mine was 3 from turbo to cat then went to 4 to muffler then back to 3 after muffler, its a 1996 so dunno if that helps. just get a mrbp straight 4" for 259 bucks and make it easy man.

 

Ya I'm def. gonna get an mbrp or farm boy diesel 4-5" sooner or later, but I just need a quick fix to a break in my exhaust line for right now. I've got a few other issues to clear up before I get my goodies

 

ThIs is another thing you can do yourself if you wanna do it on the cheap! It's def 3", just take a sawsall and hack the cat and muff out in one piece and measure the section when it comes out. Head down to napa and get the according length of pipe with two stainless steel band clamps. Put the pipe in place and bolt the clamps tight done! No hangers required since there is hardly no weight there.
