Is there a QuietCrawler equivalent for the 3.8s? (2011 JKU)
Not Really (ISH) , but it will work with a little fabbing.
So all the part numbers would be the same but on the intermediate pipe (PN 52561) the hanger will be in the wrong location. That would have to be realigned with the hanger on the 3.8.
I put together a dynomax evo competition exhaust system by buying all the parts separately for my 15jku and the sound was awful, i even stopped driving my jk for 2 weeks so it was such a turn off. I ended adding the resonator pretty much making my system the quiet crawler exhaust and wow, a huge difference. I love it. thanks dynomax!!!
