MARTYW Posted December 1, 2011 Report Share Posted December 1, 2011 Hey guys. I am wondering if any of you have any info on Jobber's Mufflers in Lexington, KY. Here is the story. The last guy that owned my truck (2nd owner) had to replace the factory muffler with a muffler from Jobber's Mufflers. All he knew was it was a "replacement" . It sounds pretty good, but I cant get any info about it. I have called their number I found online and have NEVER gotten an answer. I just need to know if this muffler out-flows a stock muffler or not. I think they make mufflers for the aftermarket, i just dont know which ones? If it is truely a stock replacement, I am going to upgrade to a Magnaflow. But, if this thing flows like an aftermarket muffler, I wont bother. Do you guys know anything about Jobbers? What would you do in this situation? I need opinions! FYI - If I upgrade, I just plan to replace this stock-type unit for the Magnaflow. Leave the stock configuration. :banghead: :banghead: :banghead: Quote Link to comment Share on other sites More sharing options...
T-Bag Posted December 1, 2011 Report Share Posted December 1, 2011 (edited) No idea about Jobbers, maybe McMahan would know being from TN. Just a little info. for you, keep in mind that the "stock" OEM muffler is actually a dual in/dual out with a Y into your tail pipe. The positioning of the stock Y after cutting out OEM muffler won't work with a dual out muffler cuz of the way the stock Y was made. It will need to be deleted and a single piece will next to extend into a single out Magnaflow. This is of course if you want to keep the stock configuration as you say. Also disregard the above if your current muffler isn't OEM style. To me this would answer your ? if it's OEM or not. I wish I had a pic to use to explain but the OEM muffler dual outs are staggered in position, not equal if that make sense like most dual out mufflers. To me if your muffler exits are horizontally even it's an aftermarket. If one higher than other it's OEM.

MARTYW Posted December 1, 2011 Author Report Share Posted December 1, 2011 (edited) I think I understand what you are saying. I will look at it again to see if the outlets are perfectly horizontal or slightly offset. Thanks for the input!
