BEST exhaust system

[DirtDonk]

Hey, I resemble that remark!

I don’t see too many mention a 2 in 2 out muffler option, what kind of performance change are we talkin vs a 2 into 1 option.

I prefer a 2 into 1 system, it smooths out the tone and eliminates the need for an X pipe or H pipe to accomplish the same thing with only 1 tail pipe to deal with. That being said I think with a vintage style restomod where you’re chasing a vintage hotrod look dual pipes are almost required, on my last 2 of those builds I used a 2 in 2 out muffler with an integrated X pipe in the muffler. I normally do everything I can to hide the tail pipe, it is very difficult to impossible on most bronco builds.

On the performance side of things I don’t think there is an advantage of one over the other with properly sized tube and not using a muffler designed in the 60’s for an OEM. If you can fit them many of todays OEM mufflers are very quiet and flow quite well.

I always get a chuckle out of a new member posting up a question when 10 or 15 of us chime in, make all kinds of "been there, done that" references and we never see another post.

Maybe they have a life and we don't so we check CB more often??? lol

LOL, maybe they just busy We'll see at some point (Maybe)

I have a two into one (cat then single Flowmaster) then into two system. It satisfies the crossover issue by just dumping both sides into a single muffler, then satisfiies the symmetric look that you get from duals out the back. No complaints.

I put Duffs exhaust on my 75,u can choose different mufflers & different exit bends. Put a nicer chrome tip on it you will not beat price and u can install them yourself, only hand tools needed.

Like V75bronco post that was dated 6/26/21, I have a question about a replacement exhaust system. As it now stands, I have a dual exhaust system with the stock exhaust manifolds. The existing mufflers have holes, so they need to be replaced. The problem I am having is that I tried to remove one of the exhaust lines from the manifold, but found that the bolt was frozen in place and could not be removed. I tried soaking bolt in penetrating oil on a regular basis and kept trying to loosen, but the bolt just wouldn't budge. So, my questions are as follows:
1. I am looking at updating to headers and an exhaust system that will fit the 72 without pulling the engine or having to unbolt a lot of other parts. I noticed on Bronco Graveyard that they have United Pacific Headers and an exhaust system that look like they are meant to bolt up without any fuss. Has anyone tried this product with success? Is there another manufacturer that you would suggest?

2. As I said in question 1, I tried to remove the bolt with no success. Is there a sure-fire way to remove a frozen bolt short of snapping off the head of said bolt?

Almost any advice is welcomed.

get the stud hot....melt some candle wax in the threads from the top side...learned that one a long time ago

 

[Yeller]

heat is your friend on those. I've even had candle wax fail, more heat was the answer which removes the stud from the manifold. The wax trick usually works.

Wish I’d have known that before I broke some door hinge bolts.

Crayons work as well. Some of us that is all we write with, so plenty on hand.

If you break one or all, put a washer on and weld a nut on the end of the broken off bolt. Heat is your friend

 

[DirtDonk]

Crayons. Good point! Probably not just a few of us could find spares in our defroster vents, under seats, and behind the panels next to the front seats!

stock heads, stock manifolds, simple 2 into 1 magnaflow dumping at passenger rear corner.
big heads, fat headers, 3.5" collectors, 2 into 2 with resonators on both pipes..

your choice
