40hp with a chip? If so, they’re lying to you. I think the highest gains I’ve seen with a chip/reflash is 15hp on a base Boxster. Turbo cars see greater numbers in chips than NA cars.

Fabspeed Maxflo exhaust is what I recommend and run. Oh and if you email Fabspeed they’ll give you a better price. I got $100 off just by emailing them.

Whatever you buy, make sure you get something in writing saying there is no cabin drone or resonance at 2000-3000 rpm or they'll give you your money back. I've yet to hear about an aftermarket muffler that doesn't produce headache-inducing drone with the top up.

This is just my opinion but no exhaust will increase hp, you may get better sound which makes you think you are going faster but you really aren't. The cost of a Fabspeed or similar exhaust is very expensive since all you are getting is a different sound.

As previously mentioned, almost all of the aftermarket exhausts will give you an annoying drone at 2k-3k rpm. I have done the cheap Chinese exhaust which did have a good sound but had the dreaded drone and it felt like I actually lost low end torque

If you want loud and don't have to worry about having a conversation with your wife while you are driving then go for it. If not, then it will not be money well spent

Just FYI, I have a GIAC flash and a RUF exhaust and they made no noticeable difference in hp. With the GIAC flash I gained a little bit in low end throttle response but my track times stayed the same.

Personally I would spend the $$$ on suspension and DE registration fees
