i now have a sputtering sound coming out of the tailpipe after installing my new mbrp single w/ cat delete. it sputters w/ the 5" tip installed and without. it didnt sputter w/ the stock exhaust at all, i cant figure out what is causing this, but it is really loud and very noticable even from inside the truck. it sputters at idle and while driving. anyone know what it could be? i hope someone can help, i love the exhaust tone the mbrp has, but the sputtering sounds rediculous.

 

every truck i have heard with a mrbp exhaust does that for some reason. im sure somone else will chime in

 

Mine does too. I have the 5in and underway it sounds great but in the parking lot it sounds like chitty chitty bang bang!!!!! Hello stacks.

 

exhaust leaking?

 

No the sound is actually at the exhaust pipe. Very strange. I just cover the sound with the distraction of black clouds of diesel...

 

yeah, the sound is coming out of the tip. i may try re-installing the cat and see if it goes away. other than that it must be the muffler they use?

 

i think it is the muffler because my truck is straight piped without a cat and there is no sputtering just bad highway drone. let me know what you find out because i am going to put an aftermarket system on to get rid of the annoying drone good luck

 

I've got a 5" system-- have not ever noticed a "sputtering" sound... I will have to pay more attention

 

how does that 5" system sound how is the ride on the highway

 

Mine sounds great, I can't hear it with the radio on even with windows down. But if I get into it, it sounds great. Except at idle..sputtterrrrrrrr

 

Delete the muffler.

 

i just installed the cat and the sputter is completely GONE. while i had everything apart i started it up w/ only the downpipe and i could hear the sputter so im guessing the sound was coming from the engine or turbo and the cat was absorbing the sound. maybee some other aftermarket mufflers do a better job of absorbing or hiding the sputter when straight piped?? all i know is NO MORE SPUTTER!!!! only problem now is the exhaust isnt as loud, oh well.
