PLEASE NOTE!  These cutouts require that you have exhaust dump pipe(s) installed on your exhaust system.  Please allow 2 weeks for delivery of these items.  

ATTENTION CANADA CUSTOMERS!

From now on we will only ship to Canada via UPS ground or Global Express mail PLUS an extra $20 charge for Canadian shipping.  If you are still interested in ordering this product you must email us first about it to get the actual charge for sending to Canada.  This is beyond our control as we have recently lost two orders to Canada.  Apparently someone in customs likes our cutouts! 

LEGAL DISCLAIMER

Please note that for legal purposes that this cutout is recommended for vehicles that are used in off-road situations like racing.  Dump pipes that replace the catalytic converter are illegal for street use in most states.  The increased decibel levels when running the exhaust cutout in the open position may get you a ticket for a loud exhaust!  What you do with it is up to you.

PRICES STARTING AT $189.95 FOR A SINGLE CUTOUT. 

DUAL EXHAUST SYSTEMS AVAILABLE TOO!

INTRODUCING!  
FOR TURBO DIESEL TRUCK ENTHUSIASTS

4" SINGLE CUTOUTS!

Same design as the rest of the cutouts we sell, just huge for your turbo diesel truck.  Includes a 3 bolt flange for connecting it to a 4" y-pipe which YOU will have to have fabricated.  Also includes a 15' wiring harness with double momentary switch.

ALSO AVAILABLE IN A DUAL SYSTEM TOO.

One thing that always bugged me about my Grand National is how quiet it is. We just don't command the respect of say a 69 big block Camaro rumbling into a cruise nite or show.  Sure, you can put on a 3" single shot exhaust like I did at one time but the sound from that gets old real quick!  I have since switched my GN to a Hooker cat-back dual exhaust with Aero Chamber mufflers.  Louder than stock but not as annoying as the 3" single shot exhaust but it just doesn't announce your presence like a louder exhaust.  Wouldn't you like to have it both ways?  Make your car loud when you want to and then quiet it up when out with the family or coming home late at night so you don't annoy the neighbors?  

This  will get the crowd's attention at car events and it also lets you open up the exhaust to decrease backpressure when racing without crawling under the car. The electric cutout bolts on to any dump pipe using a standard, 3-bolt header flange!  With a flick of the switch you can go from quiet to LOUD in about 3 seconds.  While fully open it can be quite loud but  you can also stop the cutout wherever you want to get the exact exhaust note that  you are looking for.  I usually run mine about 1/3 of the way open.

This setup is top notch in machining and wiring.  It also seals very well when closed which is what I have been looking for in an exhaust cutout.  I would not sell a product that I wouldn't use on my own car.

The wiring harness is a work of art!  You can even disconnect the cutout and remove it from the car as it has a plug about 6" off the motor.  Very important if you have to go for emissions testing or vehicle inspections!  

I mounted the cutout switch in my ashtray switch panel that we also sell. Click here to see that page.  IMPORTANT!  If you order one of these switch panels please let us know that you are using one of our Exhaust Cutouts so we can supply the proper size switches to match the one used in the cutout wiring harness! 

Wiring up the cutout is easy.  I used a fused power source that is only on with the key on from my switch panel in the ashtray and ran a ground in the same area.  I then ran the cable to the motor thru the floor grommet under the console where the shifter cable goes thru so there is no need to drill a hole in your floorboards unless you own a column shifted Turbo Regal.   The cable was tie wrapped to the transmission crossmember and over to the cutout motor being careful not to come anywhere near the exhaust system.   Installation time takes about 1.5 hours and the hardest part was removing the console for access to the floor grommet.  Obviously, it will take a little longer if you need to drill a hole thru the floorboard for column shifted cars.

I have been running one on my GN now for three years and it is cool to open it up when pulling into a show or on the open road.  My wife likes a quiet car, so for normal cruising around with her and my son in the car, I keep it shut.  If I come up in back of a Mustang though, I will open it up and usually scare the wits out of the driver.  Lots of fun! 

NOTES!
Most test pipes with dumps usually have weld on bolts that sometimes just aren't welded on straight and are very short.  For an easier installation we suggest that you cut these bolts off and use longer bolts.  We have also seen the flange on the dump portion of test pipes welded in different positions.  Guess it all depends on the welder's mood that day!  The bolt holes are slotted to allow some adjustments but on occasion there may not be enough adjustment because of the way the flange is welded.  If this happens with your installation we suggest having your welder reposition the flange.  On Turbo Regals, the heat shield for the catalytic converter should be removed for additional clearance for the motor of the cutout.  This shield is not necessary if the cat is off the car.  Four little bolts and it comes right off.  

IT IS IMPORTANT TO CHECK FOR PROPER CLEARANCE TO FLOORPANS AND FRAME RAILS ONCE INSTALLED TO ALLOW FOR MOVEMENT OF THE EXHAUST SYSTEM UNDER TORQUE.  WE RECOMMEND ABOUT A 1/2" OF CLEARANCE.

DUAL EXHAUST INFO

The dual exhaust for V-8 cars/trucks comes complete with two of the pictured cutouts and are tied together to one switch through the wiring harness.  This allows both cutouts to work together so they will be opened and closed the same amount.

OPERATION OF CUTOUT

Very simple!  You have one double momentary switch to operate, press one way to open and the other way to close. Let off the button when you get to the sound you want.  YES!  You don't have to open the cutout all the way if you don't want to.  Tune it to where it sounds the best to you.  It only takes a couple of seconds to go from fully open to closed.  We do not recommend holding the button longer than 5 seconds at a time and it is not necessary to do that. Once you operate it a few times you will be able to hear when it is fully closed or open.
