5.9 Factory Exhaust Upgrade..Aftermarket?
When I bought my truck it looks to have an aftermarket dual exhaust upgrade. Trying to indentify it?
Dynomax single muffler which looks like it might be a 4" inlet and dual 3" outlets? Dual tail pipes exit each side of bed behind rear wheels and have chrome tips.
Did the 2007 5.9 come with factory 4" exhaust? I also notice the CAT is still there. Do you think I should remove it?
