How to get exhaust popping?

[Mr.Hotrod]

Well i have an 88 Ford B2, and i had to run it straight piped because i screwed up on my exhaust. My cats are hollowed out from previous owner, and when i was running straight piped and i let off the gas, it didn't make a sound... It just hummed down to rpms, and i like the exhaust popping sound! How do i get it?

EDIT: I have the 2.9

Big cam, big pipes, and advance the piss outta the timing.

Headers run out some very short very wide dual pipes would be a good start.

Run true duals, meaning 2 seperate pipes, one for each header, with no y, x, or h pipe.

The exhaust pulse with a crossover pipe keeps that from happening.

Wierd I had no cat, and straight piped, and 2 different muffler combos and it was raspy as shit. U have a resonator still?

O well don't gotta worry about a shitty sound when I get done with the 5.0 swap

a chambered muffler will do it as well. my b2 has a single chamber flowmaster and it does it a little. with a dual chamber on my old truck as soon as you let off the gas you would get 3-4 of the "pops" but that was also a v8 (dodge durango 318 v8)

Glass Pacs work real good for this.:icon_hornsup:

turn up your idle speed screw, you'll have to play with it a little until the computer can't detect closed throttle anymore

the computer detects throttle closed, low load, high rpm. and shuts off fuel during coasting

i'd rather just save a little gas lol

Yea but tailgaters tend to back off when a 4 foot flame comes from under the truck;missingteeth;

 

[Mr.Hotrod]

Okay i am running a single 2" flowmaster 44, no popping, only very little at low rpms, my dads 76 f250 sounds like a popcorn machine going down the road. So how do i "mess" with this throttle screw? Just keep turning it in and out till what? And no, my car never came with a resonator when i bought it. It has 2 cats, and a flowmaster.

The size of the cam will have something to do with it too.

But it's not as easy with a fuel injected engine as it is with a carbed one.

I've always found that a slight leak at the collector on the manifold will produce a good amount of popping.
