So whats everyone doing to their pre-MAF (speed density?) Broncos for performance gains? Im just curious.

 

Gear change, new exhaust system

 

whats already been said. gears typically when running larger tires. the exhaust though is a must as the stock system is very restrictive.

Please fill out your signature with stats on your bronco. would help knowing engine,tranny, year etc.. and any mods it does have like lift tires etc..

 

Here is what ive done e fan swap msd coil and msd cap and rotor Taylor wires good iridium plugs advance timing up about 2 degrees synthetic fluids k&n air filter and take the intake tube that puts air in the box off and put 1 from a f150 with a straight 6 in it on in its place as it lets more air in also gears do help alot with bigger tires such as mine has 33s on it and I put 3.73s in place of the stock 3.55 and it truly made a night and day difference also deleting the cats and just running a flowmaster helped mine alot also deleting the smog pump and ac pump helps. After all of that my bronco out does my buddy's that has a 5.8 and mines a 5.0 but all the same mods apply wether its 5.0 or 5.8

 

The gears will be the biggest, most noticeable change.

 

Don't delete your cats. It's an ****** move.

GT40P Explorer engine, shorty headers, 3 inch exhaust, computer chip, timing bump, and 4.10's.

 

True.

The fourth post above is just a big blur of words, and I only picked out a few phrases.

My eyes glaze over.

 

Me too. My eyes are gettin older than dirt.

 

But what y pipe assy? If it was in my brain 2 1/2" y going into 3" with high flow cat.
The commercialy sets available are 2 1/4" into 2 1/2 I think.
I may build a y assy for mine..I'm not sure yet.

 

What the hell did he say?? I could not read this. Go to school Dude.

Or back to what ever country you came from.

 

I have a 2.5 going into a 3. Local exhaust shop built it for me. Turned out awesome

 

That's in my head what would be a good combo.I may just order up some bends.I will let the shop do the cat back and I will build the front.

 

If you don't have to pass emissions, ditch the cat all together. They're the major restriction in the exhaust system.
