I got a zzp midlength header and downpipe its catless and loud as hell my muffler is just a straight thru fart can and its loud! what muffler will make this less raspy.....

 

Stock, dynomax super turbo, stainless steel works or Walker

 

the header and downpipe made a huge diff i don't wanna loose anything a little bit on noise is ok but this thing gets stupid loud its crazy i debated throwing a cat back in there but i wanna try muffler first....

 

I meant stock muffler like the lnfs, since its a 2.5

 

do dynomax super turbos sound good or still stupid loud and raspy?

 

i have a dynomax super turbo muffler with a zzp down pipe, its sounds ok its a little raspy around 4500 and up but if you got an intake, you can still here the s/cer. its more drone inside then noise outside that you gotta worry about.

 

Im working on a possible fix for us loud m62 guys, I will update you next week, parts come in monday

 

Get rid of the ricer muffler. Get a super turbo, and a resonator.

 

Listening. I have an M62 L61 - pacesetter header, catless, TWO no-name small bottle style resonators and a magnaflow oval muffler, and it's just too loud. I've considered running a vibrant super quiet or moroso spiral flow in place of the cat frame, but i'm open to suggestions on changes other than the muffler.

 

I'm battling this right now as well. OTTP long tube header, catted, Magnaflow resinator and had a Borla Pro XS muffler which is straight through. It was loud as *****. I installed a Super Turbo. It was quieter on the highway but still way too loud. Don't waste your money on a Super Turbo. 9am Wednesday I am getting a Walker Quietflow installed. From the sesearch i've done, it's the answer. I'll let you know Wednesday how it sounds.

it works!!! just installed it, lost high end tq and gained back that low end I lost when I upgraded my exhaust, I couldnt be happier, the exhaust still rumbles but you know can hear the whine at all ranges of boost!!!!!!!!!!!!!!

 

Stainless works chamered muffler and the biggest resonator that you can find is the solution. Can't really get rid of the rasp unless you put a cat back on.
