Cat Delete?

[jump15vc]

I have a 2006 350Z and the only mods I've done so far are a CAI and plenum spacer as well as michelin ps2's all around. The car handles like a go kart but could use more power (boxter s pulls harder) so I've been thinking that a cheap and easy way to get an extra 10-20hp would be to do a cat delete and go with test pipes. I live in Florida so I don't need to worry about emissions inspections and I don't think the sound and rasp associated with test pipes would bother me too much. I've been sitting on the fence with this decision for a while, part of me thinks that to do a cat delete I should do an aftermarket exhaust as well since the stock exhaust probably isn't designed for the extra air flow and heat. What do you guys think?

(my friend did a cat delete on his 996 Porsche C4S and while it sounded great and was crazy fast, the baffles on the porsche sport exhaust that muffle the exhaust sound kept failing due to the extra heat and pressure. I think he wound up replacing his mufflers 5 or 6 times, but idk if that would happen to my car since the Z has no baffles)
