Exhaust Question

[85Skwairbody]

I just purchased a 1985K 10 all original, with the 305 engine. There is a hole in the back of the muffler. I’m contemplating either getting a new muffler or changing the single exhaust system to a dual exhaust system. What do you guys think?

You probably won’t notice much difference on a stock engine going to dual. Other than sound. A new quality muffler would probably be the best choice at this time, and least amount of money to get done.

Ok thanks, you read my mind because that’s what I was thinking, would it make a big difference with the 305? Definitely cheaper to just replace the muffler… Do you have any suggestions of what muffler to go with? I’d like to have it a little louder than stock, but nothing too crazy.

I’ve always been a fan of flow masters but I haven’t bought anything in a good bit. The last time I did I happened to get the last set of original super 40s for my k5. But that was 20 years ago…

My c10 currently has thrush I believe on it and it’s got a rumble when in the throttle but fairly quiet at idle. I would just do some YouTube searches for mufflers or see what some of these other guys may suggest.

Yeah seems like a lot of people like the Flowmaster 40 series. Thanks for the info

I have true duals in my 78, and have had duals in a couple other trucks. At this stage in life, I would just replace the muffler and be done. I’ve primarily had flowmasters, but I would look at thrush, and magnaflow as well.
