I do on my blue Challenger. 3-1/2" off of the headers with a Dynomax bullet muffler that I cut in half and made 2 mufflers out of 1.

3 1/2" might be a little big for a small block! 😂

It kind of depends on how loud you want it!

What engine (modifications) and what is your intent? Strictly racing, street only, combo?

2.5 from headers to x pipe, then run along the tunnel to Summit welded mufflers, Turn downs come out of the mufflers towards the tires.

Engine is a small block at 11:1, so its got a bit of growl too it. It doesn't seem loud idling in the garage. I haven't got it out on the street yet. I anticipate it may be a bit loud and possibly drone at road speeds because at a certain angle, you can see straight through the muffler. Contemplating running tubes over the axle into a resonator if it is, but we'll see. I might also consider a swap to Dynomax Super Turbos to tone it down. We'll see once I get it on the road regularly

I dropped mine off at the muffler guy and said I wanted 2.5" pipes and electric cutouts. He did the rest. The cutouts sit a little (lot) lower than I was hoping for, but they're fun and the exhaust looks good when I'm under it.

If you live/drive on a dirt road, be aware that the exhaust going up and over the axle then dumping downward will kick up a lot more dust than a straight exit parallel to the ground.

I just have 2-1/2" full duel exhaust on my red Challenger with Flowmaster mufflers to the stock tips. It sounds great. Nice rumble and not too loud.

TTI 1-7/8" Satin Ceramic-Coated Headers with full 3" TTI H-Pipe (circa 1999) and Dynomax Super Turbo 3" mufflers.
I agree with @Spyder on turndowns. They blow dirt everywhere and piss off others at shows when the cloud covers their cars.

I actually think it is too loud and may install a second set of mufflers in the straight section on either side of the fuel tank. That is where the factory 27" long x 7" round mufflers were installed. I am considering either Walker Quiet-Flow SS round mufflers or a bullet style muffler like Flowmaster FX or FlowMonster
12867-FM which will not take a lot of work to install. Of course I am keeping the Super Turbos in place.

Dumping exhaust under the car is a good way to get Carbon monoxide poisoning inside the car an a cruise.

On my blue Challenger. I have since this photo turned the turn downs to face inward towards each other to cut down on the dust at shows. No carbon monoxide issues with driving all over on the street.
