i want to put a flowmaster series 40 muffler in place of the stock. It says its made for my make model and year however its only 13.5in length and the stock is 24in... so i need an extensions of some sort? also is it okay to just clamp it all together or do i need a sealant or gaskets of some sort? never done this before any advice will help

 

Just go to a local auto store and get a length of pipe and 2 couplers in the size of your pipe (should be 2.5") ]. You can clamp it all together but get stainless clamps if you live in a northern area or somewhere that gets snow, regular will rust right through over winter. At least mine did anyways. Even if you wanted just clamp the muffler to the pipe coming from the engine and be done with it, so long as its not near the tire, i dont have tail pipe on my glass pack.

 

thank you! another question though how do i get the old muffler off? i loosened and moved the two clamps but it wont slide or rotate at all.. as far as i can see its not welded and its actually not that rusty at all either.. so is there some sealant thats stopping me? if so how do i get it off? i really dont want to cut the pipes

 

I will move this to the 2nd generation Dakota sub-forum.

 

You're going to have to cut it. Crappy u-bolt clamps pinch the pipe together and make removal impossible. That's just how working on exhaust is.

 

above all use ant-size on ALL bolts on the bottom of the truck. latter you will thank me.

 

I just going to to cut the pipes I have to put an extension in anyway so it's not a big deal. But where should I put the extension? Towards the front or back of the truck? So extension the muffler or muffler then extension to the existing pipe?

 

There maybe a heat shield above the old muffler. If not just look for the best area, it really won't make a difference.

 

Going to cut old stuff off clean everything up.Use a sawszaw. Definity use anti-seize when putting back together.
