anyone intalled NHP full exhaust???

Personally, I wouldn't sink any money into an exhaust until we get more info from Jake Raby.

Jake has intimated that only a couple of the aftermarket setups actually outperform the OEM gear and that most actually underperform OEM.

I understand what you are saying. after market support for the boxster's is fairly new. NHP is providing dyno sheets with each part. And the OEM exhaust seems very restrictive 1 1/2 inch exhaust inlets?????? I just can't imagine how going to a equal length merge header and from 42mm to 50mm overall piping, removing 4 restrictive CATS is not going to out perform OEM. I can't believe that's possible.
wish I could do a pre and post dyno on this install but I'm afraid I will only be able to do a post dyno. Let you know in a few weeks when I return home. Also the muffler is straight through no baffles.

Stephen,
I understand.

The IMS issue is most certainly the biggest issue that we must quantify before any public statements or made. I have already been asked to be an expert witness on more than one occasion in ragrd to the IMS failure.

I believe in solving the problem with a wrench, not a Gavel.

I will put an end to this. This is going to completely set back my plans. I will do a Pre and Post Dyno on this install. and if I have a negative gain in Hp and Torque then I will shut my mouth and offer a personal apology to Mr. Raby.

end of story.

this will take some time I am currently on travel for govt.

exhaust has been delivered.

shooting mid july pre dyno.
