after i cut my cats out, my muffler made a god awful noise , kinda like i had straits with 20" echo tips, it poped and crackled like i dunno what, so i changed the muffler to a magnaflow, and didnt put any tips on it just straight muffler and it didnt do it , so i put my tips back on and now it does it!!!! i just want to know what to do cause i dont want to be known as the guy with a sport truck sounding like an old cowboys truck. PLEASE HELP!!!!!!!!!

 

Get some different tips!!!

 

dump the exhaust directly after the muffler

 

drop the tips and dump it.

 

well i want to dump it but where i live, that would suck really bad cause of all the dirty nasty roads, and driveways!! and the fact i have a black truck

 

mine does the same thing... Im cutting the tips off and doin a single 3 inch hooker max flow dumped over axle. That will get rid of that awful popcorn sound.

Yes, over the axle is the way to go!

 

The crackle and popping is raw fuel vapor that the cats would have normally burned off. Mine does thiss too, plus its tuned rich so that doesn't help either.
A tuned exhaust sometimes helps. Bu tuned I mean trying different length of muffler/tailpipe combos.
I used to deal with this crap allot on crotch rockets in the past. Some exhausts would crackle and pop when letting off after heavy throttle and some would not. It depends on the length of the exhaust pulse and how well your exhaust system flows.
I will never be able to get rid of mine unless I move the turbo up or back.

 

i hate the poping and stuff, but i love my exhaust including tips, so i guess ill just have to deal with it, i mean it sounds really really racey, i might try to get the same style tips just a lil shorter, that might help

 

try putting a short bullet right in front of the magnaflow, I have heard this helps cut out a lot of the rasp.
