$5k plus for a muffler o_0

Are you talking dpfs or what ? If not I'd check into after market or strait pipes. Or even go to single stock exhaust ......

 

I have a Columbia with c 13 and dual mufflers like you,my muffler was little more then $ 130 EACH ,from PP

 

Are you sure? Theres no way. But the good news is thats not true. They can be had for way, way, way cheaper.

 

Those mufflers will have catalytic converters built into them.

 

I can't say that you have the same mufflers but I ran across something similar. http://www.thetruckersreport.com/tr...lers/197451-06-freightliner-c-13-muffler.html

The first Donaldson I put on cracked at the top within a few months. They replaced it at no charge. The second one has had no issues. The diameter of the Donaldson is not the same. It is also just a regular muffler.

 

Just buy the quiet performance mufflers from Pittsburgh power (or Donaldson equivalent) there like 150 a piece and may give you up to 50 more HP.

 

HeavyD is correct.that is why so expensive.

 

Why do you need CC on a truck....I though CC was only needed on gas burning vehicles. If its before 07 all you need (to my knowledge) is a muffler...and some guys run strait pipes.
