Hey, just thought I'd let everyone jknow that Autozone can get a 4" Flowmaster Exhaust, It a universal kit a requires a little cutting, and its from the back of the cab back, but it seems like a really good deal for 129.99, I have one on my F-350 with a 460( I know, its unnecessary) and it sounds great, I'd imagine anyone wanting a big exhaust on their IDI would be interested, so just stop by your local autozone, also they offer a 4->5" clamp on Flowmaster tip for 39.99. Just thought I'd let everyone know, enjoy.

The part number for these are:
-15929 for the exhaust
-15368 for the tip
also, If you decide to clamp the exhaust rather than weld it, the cheapest place i found clamps at was Advance Autoparts

 

got any pics?

 

You can buy that through AMAZON for $112.28, NO TAX & NO SHIPPING COSTS! That's $112.28 delivered to you door!

 

Muffler..? What is this muffler thing you speak of?? I would say 4" is about right for a 460, especially if it has a chip / intake / headers those king of things. I was runnin dual 2.5" on my 77, quite a noticable difference, went from 1 7/8 primaries to 2" and 3" collector to 3.5", it wasnt quite stock tho. Anywho now that i realize im hijacking, thats not a bad price at all to run 4" over the axle, is it galv or aluminized?

 

aluminized

 

Pictures of it are in my album, Its aluminized, mandrel bent, and definitely seems like a good deal for an exhaust this size, beats those 600+ dollar kits for the newer trucks by a long shot

 

Yah but aren't a lot of those $600+ kits stainless??

That looks like a good deal, I may have to remember this. Currently I'm running a 3.5 exhaust off some version of a powerstroke. It doesn't really exit where I want, and I'm wondering if the muffler is restricting it any. Anyways, I'll try to remember this if I decide to redo the exhaust this summer. I was thinking to either go to a straight through muffler, or just cut out the muffler and throw in a piece of straight pipe, but I'm not sure how the part over the axle would work out.

 

i got my turbo back exhaust SS for $300 shipped to my door.

 

Exactly what i was looking for. Was thinking of up sizing my n/a from the tiny exhaust it has now. The rest i can make up.

 

Glad someone got some use from this thread
