Bolt in down pipe?
Does a company sell such a thing? I saw a few years back, a member made a custom pipe from the headers to the resonators that deleted all cats and was straight bolt on. I would be very interested in purchasing something like this if it existed.
If not, what is the cheapest solution to deleting all the cats, just cut and weld straight pipes?

I made that per customer request and have that setup hanging on the wall at the shop. It is a constant reminder that all removing the cats did was make more noise. On the dyno and at the track the setup traded a little down low tq for a little top end hp. I always thought putting in an x pipe would make it a little better. But never got around to it. So if you want a car that is as load as one with headers with the same power as stock. The car did have a secondary cat delete with an x pipe before this so not quite stock.

I have bought from GT-pro (www.ronalsales.com) what you are looking for. It is a down pipe and an x-pipe. It replaces both set of cats. I did have it dynoed before and after and it did give me a little over 10whp. I did not do it for the hp gain but for the sound.
It is a perfect bolton and nothing needs to be cut.
I am thinking of switching vehicle so I may be inclined to sell my set up and put the car back to stock. Let me know if you are interested
