Time for a muffler replacement...

Muffler is full of holes and is sounding nasty with a terrible drone!!! My truck is an 02 4wd TRD w/3.4L 145k miles and i am askin if its better to get the whole aftercat done or if just doing the muffler is ok?? I like the sound of the magnaflow but cannot figure out which of their mufflers would fit my truck best...any help appreciated!!! Thanks

 

all of them would fit, its just a matter of what sound you're looking for. the size mufflers are 14", 18", 22", and 26". 14 is the loudest and 26 sounds stock. i have a 22" and its a little bit louder than stock. not as loud as i would want it to, but i have a kid and personally i think the 18 would probably be a bit too much drone

 

My muffler is on it's way out too. If you just buy the muffler, rather than the whole post-cat deal, what do you do? Cut the pipe at the old muffler, and the new one slips on? Or does it get more complicated than that...

 

I got just a dynomax super turbo part number 17748. I sawzalled off the old muffler and slipped the new one over the old piping and welded it up. Then I cut the tail pipe just after where it goes over the axle and welded that onto the other end of the muffler. Easy and the super turbo is nice and quiet with a butt dyno proven .0005 hp increase

 

You're usually going to have to do some welding. Call up a local shop and ask them what they'd charge just to install a muffler that you already have. Sometimes they don't carry the one you want to put on, so just get an installed price and then order the one you want.

 

In my sig.
