where to by 51" donaldson muffler in Fort Meyers, FL area?
 

Hello everyone,

I have roughly a 30" straight thru muffler and I would like to add a 51" donaldson muffler behind my current muffler.

Truck is quiet when not pulling a trailer but gets loud with a heavy load.

Any suggestions in the south west fl area would be helpful.

Thanks

SAS

I got mine at a cummins big truck dealer,had a 5inch x51 with reducers to 4 inch outlet.I took it out and put in a 30 inch flo pro,still too loud ,so added on a 36 inch magnaflow, all straight thru 4inch .It is very nice.I think the 51 added on would be too restrictive,a40 inch would quiet things down nicely.

What is the stock exhaust 2004.5 diameter? Is it 4"?

Up here in Central Florida one of the best places to check is with SE Power, Not Cummins SE Power. If you need something for the truck or the engine they usually have it.

They have a shop in Ft Meyers
