The DCS7901 muffler will be lighter than the stihl muffler. Plus it'll look a lot better!

If you gut your oem muffler you will loose a lot of weight.

While your in it this far you might as well pull the crank seals and inspect the bearings. Then throw new seals in if the bearings look good.

Welcome to the club!!

Gut the OEM muffler, open up the factory exhaust outlet - You'll have an awesome sounding screamer!

From what I saw, you've gotta use MAP gas to heat up and uncrimp the lip? I don't think I've got the welding chops to tack it all back together if it's gotta be cut apart...

Does the DCS6400 feature a Stainless Steel muffler in the US?
Hold a magnet to it, it is not SS if the magnet holds on good.

Either way, You "can" uncrimp even the SS muffler cold - it is harder to do but it is possible.
I did my PS-7310 SLR muffler cold.

If it is a regular alloyed steel muffler body uncrimping is fairly easy cold - I did my PS-7900 muffler cold.

Also, there are members here that offer muffler modding for a price.

PS-7900 muffler with baffle/bird cage.
Yes, any future mufflers will just get gutted!

Humble mod, works nicely for me and my PS-7900.

BEFORE


Uncrimp cold with side cutter pliers (works nicely, left crimp at an angle under 90° for easier recrimping)


Enlarge all existing holes and ad a few more (I didn't want to remove the birdcage entirely)


Put together and recrimp.

Dolmar PS-7310 muffler in the works.
Aiming for a humble mod, single outlet with stock spark screen, SLR pipe cut out.



I think I got my moneys worth out of that cutoff wheel.

The DCS6401 has on aluminized steel muffler just like the DCS7901.

The DCS6421 has the new fangled heavy stainless muffler.

Cold uncrimp easy then!

Ah! That plier pic is a helpful visual.

Mine is the 6421, with stainless muffler. Certainly feels overweight...Is that the style with the cat converter? Guess I'll find out when it's peeled open

Yours is the cat muffler. There’s damn near enough to make another muffler inside that thing. Gut it all out of there

Just a cat? I think this thing can pummel a lion.
