Extra long decat pipe?????

I was thinking of getting a decat pipe just for a bit more noise without having to spend the money on a cat back system, and while looking at the exhaust today i thought why didnt k-tec etc make the decat pipe about 2 foot longer so that you could take the cat and center box out at the same time...

I dont know anyone near me that could make this so throwing it out there incase anyone on here could make it or would know anyone who could make it...

Maybe a group buy if there was any interest?
 
Exhaustsuk near me made all the exhausts for pimp my ride uk, they could make it but I recon the flat spot would massive.
 
iv cut the center box out mine

sounds epic but big flatspot, i have been driving it for last 2 years so used to it now lol
