Anyone have any numbers, give or take 1/2 an inch, how long the stock main cat is or a cat replacement pipe or RB presilencer is? I am going to be at the exhaust shop with my new can that's soon to be my presilencer before I will have a chance to pull my cat replacement pipe off my car.

Thanks in advance, I'll call Mazdatrix if no one has one handy!

PS: How loud you think it'll be with gutted precat, a straight through presilencer, and straight pipe from there back? From the presilencer back it'll be 2 3/4. I'm currently running the twin scroll again, so below 2700rpm I think it might be bearable.
