Part # 49542


One look at Banks TorqueTubes tells you how radically different they are from the stock exhaust manifolds. Constructed of heavy-wall, 400-series stainless steel, TorqueTubes have 1/2-inch-thick flanges that are welded on both sides and then machined perfectly flat (no gaskets needed). They never crack, leak or fail.

TorqueTubes tuned-length tubes produce a huge reserve of low-end torque that proves its worth on every steep grade and short onramp. Now your Workhorse climbs faster and stronger, without the transmission struggling between gears. The muscle to stay in higher gears longer not only stops annoying "shift happy" performance, it lessens the load on your engine and transmission. Here's power to reach freeway speed sooner for safe merging and passing.

2004 Pace arrow 37c looking for Banks stinger only. I already have the headers and need the over the axle to tailpipe ( James, 07/15/2023 )
The Stinger kit for a 2004 W22 with driver side exit is part # 49552 ( Support )
my cats are welded to the pipe will i need to cut and weld a flange on them ( Joey Tomko, 12/14/2021 )
These are designed to mount up with the factory flange before the catalytic converter. If that has been modified, you will likely have to do some welding. Can you take a picture of your exhaust and send it to or text to 360-736-2158 and we can take a look and advise better? ( Support )
I forgot to ask if these torque tubes work with my workhorse motorhome with dual mufflers and exhaust? I want to keep my duals. ( Kaiser Ford, 08/11/2021 )
Yes, they will have the necessary pipes to connect to the existing catalytic converter flanges , replacing the front section of the exhaust system .    ( Support )
I am sorry I forgot to ask if these torque tubes have heat shields or will my stock shields fit over them? ( Kaiser Ford, 07/30/2020 )
The torque tubes have a shield in place where needed only, stock heat shields will not fit ,the kit comes with heat wrap for the nearby hoses and wires.  ( Support )
Is there a place in this manifold for an EGR or does my engine have one on the exhaust manifold? ( Kaiser Ford, 07/29/2020 )
Your VIN shows an 04 model year chassis with a build date in August of 03, the 04 did not have an EGR so the 49542 should be correct. If it is an earlier model, then Banks kit 49504 would have an EGR fitting. ( Support )
I have your ultrapower tune already, will the tune need to be altered with the install of headers. Is there any noticeable power gain at 3200 rpm or less. I'm not one of those flat footed let'er scream up the hill guys ( Thomas Ressler, 05/02/2019 )
You would notice an appreciable gain in torque under 3200 RPM with the TorqueTube headers. You shouldn't require a re-tune with the headers installed. ( Support )
what kind of power and torq increase can I expect? ( joey, 08/20/2018 )
The TorqueTubes are good for about 25 horsepower and 30 ft-lb. torque. ( Support )
How much to install on a 2006 Newmar Canyon Star on the W22 chassis? ( Damon, 12/08/2016 )


Typical installation will be approximately 8 hours. Cost will depend on the labor rate of the shop that you have install it.

( Support )
2006 Bounder 35E (but chassis built 2005) Do your p/n 49542 headers bolt up to the existing exhaust system? I will probably install myself but would like a quote from you for installation.
( James Ludwig, 08/01/2016 )

Hi James,

Yes the 49542 is designed to mate up with the stock exhaust pipes without modification. To get an installation quote please call our service facility at 877-786-1576.
