I have a stock 91 with 144K on it and the muffler finally rusted through. I was wondering what the hot ticket fror exhaust systems is on these trucks. If it was a Mustang I'd know. I'd like to have a free flowing exhaust but not too loud. I will put headers on if I have to but would not like to, emissions and all. So tell me your setups please. Could I use a bug single exhaust or is duals the way to go?
Thanks for any imput.....

Oh its a 302

 

I would suggest not going with duals on a bronco. The vacuum effect will suck the fumes back into the cab with the rear window open (and will seep in over time). You can search for exhaust in this forum. Its talked about frequently. As for headers and the like, there are systems out there that maintain 50 street legal. I have a complete Bassani system on my 96. Ceramic headers, high flow Y/catalytic , catback...all emissions legal. If you want something quiet, you might want to look at Gibson catbacks.

1992 302 with absolutely nothing from the CAT back but a y-pipe (exits behind the wheels.)

Sound is good but I would like to run open headers!

 

My advice=Flowmaster! I have a single aftmkt. cat and single-in FlowM. with dual exits behind the right/passngr.-side rear wheel. Very nice tone, not too loud. I would never run straight pipes out the back on the Bronco--too many fumes get into the cab.

 

I'll cast a second vote for the Bassani Street Thunder system. Emmissions legal, shortie headers (which are optional...the rest of the system will bolt directly to the stock manifolds or the headers), headers available ceramic coated or chromed, Y-pipe muffler, and tailpipe are 3" stainless steel with all the necessary hangers already welded in place. The fit is exactly like stock (no brackets to fabricate or modify). O2 sensor bung and high flow 3" IN and 3" OUT catalytic converter. All necessary hardware included. Muffler is fully welded across the entirety of every seam. Angled, polished, stainless 3.5" exhaust tip. Systems for both 302 and 351 engines.

I purchased this system about two years ago to replace a cracked driver's manifold and Y-pipe. I didn't spring for the ceramic on the headers, mine are just chrome. The whole thing delivered to my door tipped the scales at just under $1K including shipping. Too pricey? Considering the great condition of this system after two rotten Missouri winters (They salt and salt spray the roads here), it has been worth every penny. Especially when you consider that Ford wants $650-700 for the OEM replacement Y pipe alone. And its still made of plain ol' steel that will rust away in a couple of years anyway. It sounds good too. Not too harsh, just low rumble...and none of that obnoxious pop and belch when you come down out of the accelerator that you get with other systems (I'll try not to mention names like Flowmaster). "Cat back" is ok I guess but its still not a complete exhaust system.

 

Thanks for the imput, anyone using the dynomax cat back system? Summit sells it for 149 and its 2.5" and made for the bronco.

 

To answer the last question, I had dual Dynomax and now I went with a new exaust system from engine back and went with dual Flowmaster 70 Series mufflers and I think that they are way too loud for me. Both setup's had no cat's either and are true duals.

I am now looking for some way to quieten them down but have not been able to find anything short of installing cats.

Hope this helps,

 

Fcarruth - will small resonators fit on the end of the pipes? Haven't noticed on new vehicles, but the models from the '60's and '70's with dual exhuasts had two mufflers and two resonators (singles had one muffler and resonator). Maybe that's all you need.

 

Thanks PMD66, I'll see what I can find out there.

 

Im thinking duals on my 95 but I wont have them exit out the rear bumper because of the exhaust issues. I was going to have them either bend out the corners of the bumper, exit behind both rear wheels (near factory side sweep location) or exit in front of both rear wheels to give it something different (heard this might be illegal in some states though), maybe have the tips cut through my running boards or remove the boards all together and install small steps.

Im also in the debate of flowmaster or some glasspacks. Cats are required in NY so would have to get some high flow. I just want a nice purrrrr and then make the ground shake if i get in the pedal hard. $$$ is always an issue, gotta keep it inexpensive.
