Decat info - 2.25" intercooler kit

[Midnightclub]

Okay bit of a weird query but bear with me..

I know a couple of you guys have used a 2.25" intercooler kit, obviously this comes with various, straights, bends etc.

I have a few straights left and thought about using one of them for a decat pipe, from those who have the kit do you think it would be thick enough for a decat pipe? Is it the right material to be welded in place of the cat?

Cheers
