A friend of mine is considering this setup. Are all the pipes ( from cat back ) and the dual inlet/outlet muffler available from Walker?

Basically looking for everything to do this;

had a friend who did that setup on his 87 cutlass. Walker I believe has this system avail. I personally dont like the sound of crossflow mufflers . Another friend of mine did the Monte SS style exhaust with the tails exiting behind the rear tires

Yeah I know about that ridiculously overpriced aftermarket one. No way my friend would spend that and I wouldn't blame him. The Walker stuff is way cheaper.

My research has shown me that yes all the parts from Walker are still available to do this.

I replaced my stock GN crossflow exhaust with a $150 muffler shop non mandrel bent 2.5" aluminized duals with ultra flow straight thru mufflers and the car dropped .4 seconds and picked up 4mph in the 1/8th mile.

There is zero special about the stock GN set up. Even if I was restoring a stock GN for shows, I would put on ultraflow duals. Hard to make a low backpressure crossflow and the exhaust kept GN's from being low 13 second cars in showroom trim.

On purpose? ;)

I only posted the link as a reference - not to upset anyone's ham and egg budget with sticker shock. It is a completely accurate restoration product, and performance is not a consideration for the prospective buyer. Hell, you cannot even get a replacement piece of the exhaust system without buying the whole system initially. Yes, I agree it is silly for what it is. As it has been indicated buying a janky Walker crossflow exhaust is just a total waste of resources as there are much better options for the same money going from a y-pipe through, two mufflers, and out some behind the wheel slash cut tips.

You didn't upset my ham and eggs but I did have some sticker shock. I guess that system would be worth it to a guy who wanted to keep his car ultra stock. That Hooker system looks nice. If I had a GN and they had that system in stainless, that's the way I would go.
