Ok, i need some advise. I had a borla pro xs muffler that I blew out and it sounded bad off so i changed to a magnaflow 11inch and I blew it out within like 2,000 miles. Now im wanting something quiter and something that will hold up. I drive my truck like a race car and need something that will not blow out!

 

I run a magnaflow 12219 muffler, sounds great and wont drone if you have cats.

It's 14in case and 20in long overall. Though it's only been on for just over 1,000 miles it holding up great and I highly doubt it will "blow out".

I bet it will never blow out

 

What are the details of your truck (year, model and engine size)?

 

I have had great luck out of Spintech mufflers. Never a broken weld, rattle or problem. They'll build you whatever you want. They're chambered but very well made and I haven't noticed a restriction at all out of mine. I've ran my current one for about 40K miles.

 

2006 vortec max.. Cammed, full bolt ons with no cats. 6.0

 

I second silver-mod-o, I love my Spintech and will swear by them forever

 

If you are still running your factory exhaust setup (dual inlet/ single outlet) I would recommend a Flowmaster 50 Series Big Block muffler. We offer this muffler in a dual inlet/ dual outlet configuration as well, if you wanted to go that route.

 

To the OP, do you have any sound clips of your previous exhaust setups?

 

Spintech Super Pro Street or Pro Street for a DD are great and never have had problems from what I have researched.
