Muffler suggestion - 91 silver k1500.

jbbarry · 09-26-2009, 05:39 PM

Time for a new muffler. Looking for something that sounds good but not real loud. Engine = 350. Tranny = auto. Something in the economy price range that I might pruchase at an auto parts store. Suggestions??

Thank you
JBB

I have a Magnaflow also with a Magnaflow Cat it sure sounds good and mellow it's not too loud to where I can't enjoy listening to my music.

take your muffler to advance or autozone , they usually carry universal mufflers they can match to to yours and are a lot cheaper than a direct fit replacement .

what you want is a cat back VORTEX exhaust set up. VORTEX makes the pipes as well, so no messing around its bolt up, its dual out , it sounds great but not too loud, improves gas mileage . see pic. can order online or Jc Whitney, or some parts stores, its a rugger muffler, steel welded.
pic is a single out, but the truck one you want is dual out

I have a dual 2.5 in dual 2.5 out stainless steel magnaflow im trying to sell if you want an inexpensive magnaflow.They`re a little pricey new but sound great.If you want something cheap from the autoparts store all the advanced auto stores here sell the thrush turbo mufflers are cheap and sound pretty good but not too loud.

I have a magnaflow high flow cat and a flowmaster 40series 150 for the install and muffler 75 for the cat. AT least where my shop is. check my thread Exhaust that's what it sounds like. I do have 3" back from the y-pipe. Soon I want true duals though.

Look at this muffler I think it's a good price.

i like the (thrush welded) its like a flowmaster but half the price, its a welded two chamber . advance auto will match $30 thats what summit is charging.

Thrush? is that cherry bombs or glass packs which ever it is?

Friends,
Thank you for the muffler advice. I've listened sound clips of several makes. I think I will end up with a thrush. They seem to be reasonably priced and a name that I recall from way back when. I have many improvements to make on this old truck so I need to economize where I can.
