Talk me out of running duel exhaust

I just swapped in a 401 in my waggy and The oil pan isn't clearing the Y-pipe.

My excuse for new exhaust is here

I want to keep the stock manifolds. Retaining torque and all that.

I love the way duels look and sound and the Jeep will see more asphalt than offload pioneering.



I thought 2" side pipes dumped in front of the tires would be sweet.

Or will it rob me of my power and torque so I would be better off with 3" single?

I'd appreciate it.

I may just go straight pipe as I don't have to pass inspection where I'm from.

But if it has a deeper idle sound I might go for it.

Can you also show how its routed with pics or the video?

Does anyone know of any muffler shops in Colorado Springs?

And what would be a fair price for 3" straight pipe from manifolds back?

Don't dump in front of the rear tires nor behind them. You will soon get tired of the noise. Dump them straight out the back you still have the great sound but it isn't as noticeable to you in the vehicle as side dump exhausts.

Trust me. I know. I had a '10 Tundra straight piped and dumped in front of my axle. The drone drove me crazy.

I am planning it exiting out the side in front of the tire or behind it on the passenger side.

I am still curious what a fair price is without mufflers as I am on a shoe string budget.

Bud's Muffler has been in the Springs forever and does all kinds of custom exhaust work from street rods to rock racing buggies.

You will retain more torque by going with a pair of 2.5" pipes (or 2-1/4) into a single 3" pipe. If you want dual exhaust, have it split at the muffler. This will net you the most power plus it will be easier to run a single 3" by the fuel tank and or transfer case.

IMHO, you will be choking out that 401 with two 2" pipes.

Thanks for the input. Would it matter if its 3" without a muffler? Can straight pipe reduce torque and back pressure?

Like they said, don't dump in front of or behind the tires. I just had duals put on and they are behind the tires. That is going to change pretty soon to strait out the back.

When you say dump you mean underneath not side pipes right?

Yes my pipes are all under the vehicle. It comes out behind the tire about 18 inches.

Oh okay. I was thinking about running the pipes under the frame and out and dumping in front of the rear tires outwardly. Hopefully that would keep any drone out.
