I was thinking since different makes and models are manufactured differently, and a lot of parts are made specifically for certain cars that it would apply here. What about gaskets and stuff? And re-shaping the exhaust pipes to mount the cutouts?

damn righttt i love mine

theyr aftermarket so yeah theyr for any car ..

they are staring to due visual checks when they do the smog test so it's not even worth it to do this.

That's cool, makes things easy.

they are universal for any car you want. Quick Time Performance (QTP) makes them too Never seen the DMHs before but they look really nice

that would ruin the point of the cutouts, you want to make people think that it is stock. i dont know if you have ever heard one in person they sound realy good stock with their true dual exhaust from the factory

Dayamm that GTO sounds soo good with the cutouts open, but put some Flowmaster Mufflers on the car and open the car up with the cutouts closed with the Flowmasters installed and it will sound really good both ways...

Are they available for oldsmobile intrigues?

We have some group pricing setup at DixieMuscleCars(dot)com

Yes, I did dyno it. I only picked up 2hp with the cutouts open but I installed them for the noise/fun factor not hp. You can see the dyno video by looking at the videos under my username here. DixieMuscleCarscom

Sounds amazing man, I Love Chevy V8's

Great sound improvement, thumbs up! Did you test it on a dyno to check how much more hp you get when the cut-outs are opened?

QTP cutouts range from around $200 for single exhaust applications to around $500 for dual exhaust w/controllers. Im sooo putting these on my 06 GTO M6. Not that it needs it, our LS2's make Mustangs sound like leaf blowers....To the poster...Did you have any backpressure issues or torque loss?

I want that! How much$?

if you have to ask you shouldnt know haha its kindove self explanitory

They allow you to make your exhaust louder and add a few more horses when open, then you can close them when you go to the grocery store to keep the cops off you.

haha what are you a third grader?

Your moms Holden my nuts in her mouth.

can someone tell me what the cutoffs do im confused

DAMN, that thing sounds RAW

I'm happy to see Holden's influence finally reaching America. I have a 2006 Pontiac GTO (Monaro) and can't wait to pay it off and get a Pontiac G8 GT (Commodore SS, I believe). Great cars with great performance. The seats in my GTO are probably the most comfortable ever in a Pontiac. Mustang owners don't even bother to rev their engines next to me; they know better.

Keep your catalytic converters on & you'll be fine.

nice holden....
