If noise is a concern then get the Carnewal PSE remote control and wire the solenoid to 12V power. At a push of a button on the remote (or on the garage door opener, which is how I have mine setup) you will have either constant closed (almost as quiet as stock) or constant open (screamer with race cats).

Thanks for the options gents
Currently have a full IPE race exhaust system and changed from OEM wheel set,
I have found that within the UK Porsche mods are very limited but very expensive,
Had a Bmw M4 before my GT4, Mods and power ups were main stream because of twin turbo engine set up,
I fully understand that i am a newbie to the GT4 scene, But wanting ££ outlay for power gains with GT4 engine.

They also will sell you a catted version I believe as well. I almost bought a set off a forum member here, but backed out because I was told the exhaust smell would be noticeable with the top down. After debating it back and forth, Dundon said we could add cats worst case. So I bought direct from them -- should have my set next week, along with the cobb tune. As far as power, I think they're right around 438 horse on 91. Not bad, and 321 stainless! The stock PSE is def. too quiet for me. I believe they are working on their own center conversion, along with an intake manifold for more power down the road as well. I will probably buy those... I guess the throttle body/plenum doesn't really add much (any) power for these cars if you already have headers.

The only thing I would change on my 981 Spyder would be an axle lift. I hate having to stress about pulling in/out of places, driveways, etc. There's after market solutions (I believe from TechArt), but they're 2.5-3x the cost of OEM (which was not offered).

M4 power is not usable IMO. At least, that was my experience. I would consider one again for daily duty, but man that thing could not put power down to save it's life. Still liked the car though.

Yep!!! I haven't actually scraped it yet, but I have been so extremely careful it's ridiculous. Good thing the bottom chin spoiler is cheap to replace worst case =)

M4 will always be cheaper to mod than a Porsche naturally aspirated motor. You will spend big money for relatively small gains. That is the nature of the beast. I did some back of the napkin maths and for header and a tune and I will be spending what 5 grand easy for my Spyder. I am not even talking about plenum and throttle body. Frankly I don't think they do anything to gain any power. At least I am not convinced. So headers and tune seem to be the best way to go.

But yes, adding lbs of torque and more hp is cheaper per unit for the M.
