Doffer Posted March 26, 2013 Share Posted March 26, 2013 Is it legal to delete the muffler on a 2003 Mack MR688S ? I love the open exhaust sound, but I'm not sure if its actually legal or not.

Dennis Hall Posted March 26, 2013 Share Posted March 26, 2013 Some states actually restrict any modifications to the exhaust. Quote Link to comment https://www.bigmacktrucks.com/topic/30551-muffler-delete/#findComment-174417 Share on other sites More sharing options...

Dennis Hall Posted March 26, 2013 Share Posted March 26, 2013 PA is more lax, MD is a no no, NY I would not trust, shit they do db readings on motorcycles, I avoid that state with my Sportster.

Dennis Hall Posted March 26, 2013 Share Posted March 26, 2013 I was informed recently, my last trip to Beam Mack in Elmira, NY a week ago that it wont be much longer and NY will be doing the puff test like NJ has been for awhile now.

2stacksuperdog Posted March 28, 2013 Share Posted March 28, 2013 what is the leeway 2stack for. A 1996 year truck?Ill have to look tomorrow for the emissions print out when they pull you over. It shows your percentage and then what your allowed in categories like Pre-1970, 1970-1979, 1980-1989, etc. and have different allowances for each Quote Matt Link to comment https://www.bigmacktrucks.com/topic/30551-muffler-delete/#findComment-174673 Share on other sites More sharing options...
JumperAndSon Posted March 29, 2013 Share Posted March 29, 2013 One of our customers is a DOT inspector for Pennsylvania. While he was at the shop getting some flooring, he also took a peek at the International which has the 6V92TA with straight pipes. My dad asked him and he said that there was no laws or restrictions on exhaust that he knew of. So I think if the DOT officer says it's cool, then it's cool Ben Quote Link to comment https://www.bigmacktrucks.com/topic/30551-muffler-delete/#findComment-174903 Share on other sites More sharing options...
220cummins Posted March 30, 2013 Share Posted March 30, 2013 Some older turbos have "muffler device" cast on them which negates a muffler and "noise restrictions" Quote Link to comment https://www.bigmacktrucks.com/topic/30551-muffler-delete/#findComment-175012 Share on other sites More sharing options...
Doffer Posted March 30, 2013 Author Share Posted March 30, 2013 Well I have bigger issues than a loud exhaust at the moment. I think my manifold just cracked or the bolts broke or something. Definitely and exhaust leak Quote Link to comment https://www.bigmacktrucks.com/topic/30551-muffler-delete/#findComment-175088 Share on other sites More sharing options...
