One day i will have a bronco so i want to know what you are running.what kind of muffler do you have or don't have and why?.Are you running headers if so what kind?do you have cats?is it a duel or single exhaust?ect..

Wild Horses Headers thru Dual FlowMaster mufflers exiting on each side behind the tires. I have run FlowMaster on every truck I have ever owned. I think I have 40 series this time but not fo sho.

BC headers to 2 cats... 2 into 1 exhaust w/ a flowmaster 40

Long tube headers into dual 2.5" super turbo mufflers exiting behind the rear wheels. I'd like to convert it to single 3"with a quieter muffler and possibly a cat.

Long tubes from Duffy along with their dual setup....headers I like but the exhaust and mufflers are being replaced with super single with a magnaflow muffler soon.

Stock manifolds into dual into cherry bombs(straight pipe almost) into 2 knock off cheap mufflers. Exits right in front of the rear tires out of the body side....well away from rocks. So yes 4 mufflers. I like quiet. It is barely noticeable when idling.

Performance is not really a priority----gearing takes care of me!

Shorty Sanderson headers into a custom straight pipe with a Flowmaster muffler and dumping right over the rear axle.

the 74 has headers to y pipe into a 3in truck muffler(not sure what kind. big round tube) with a single 3in exit. nice sound and quiet. the 79 has fender exit headers with about 3ft of pipe and a force pro series chambered muffler(flowmaster knockoff) on each side. Sounds great but way too loud. have to wear ear plugs for trips longer than 15 minutes. I used to like the loud exhaust. Now im over it and want a nice quiet but deep rumble. Love the sound of magnaflows. Thats my next set on the 79.

Stock manifolds > Dual Hooker Competition Turbos > exits out both sides behind rear tires.

Mustang Shorty headers, some really funky piping under the oil pan to collect on passenger side and down into a moroso Spiral flow muffler because that's all that would fit around the Atlas and then pops out right behind the rear wheel, thru the body!

BC bronco's coated shorty headers ...2 1/2" to 3" super single...Magnaflo .. custom 3" tail pipe to exit all the way out bihind the right rear tire.
My bronco is a roadster and with no top the exhaust fumes would enter the back seat at city and highway speeds. When I would lift the kids out of their car seats they smelled like exhaust and slept just fine on road trips!!!! Yikes !!! So I did a lot of experimenting to not get "Fumed" and came up with the super single out the rear side.

Lets see some pics JM!
