I am in the States, and I just got the exhaust bypass valves from Spyder. I did removed the stock mid-pipes with the secondary cats. The secondary cats do not affect our emissions or your ECU, no codes. The install was very easy to do, and the sound is amazing. Cold start with the valves closed is loud at first, and then it mellows out. Driving with the valves closed it sounds a little louder than stock, I think because I don't have the secondary cats. Driving with the valves open is nothing short of amazing. I highly recommend these if you're looking for an easy, cheaper, solution to other valved units on the market, and you want to have a nice flat six roar at WOT and higher RPMs.

Every sports car should come with this from factory

Fabulous video and good quality looking kit being installed by the pros.

Nice video & product! 👌

Will these fit on the factory sports exhaust (showerhead)?

What is the red hooped wire for?

hi is there any way to hardwire it to the Porsche sports exhaust button

Hi,

I live in Japan. This exhaust is very exciting. I tried to purchase from HP. but therr was no shipping address in Japan.

how can i get one of these and do you do these for the Porsche 987S?

Fab! Can you do this to my wife’s 2007 Boxster S? If you like to use it for a future video you will be most welcome.

I have just installed mine today..... advice..... I spent 4 hours installingrs trying to find out why it was not working.... in the end was simple because the central black box was not properly connected................... 2 hours to get it..... so, double check the connector before installing it.... my 2 cents...............

Straight pipe the secondary cats and replace that really heavy stock muffler.

Can you get the same sound by just deleting the big muffler and run straight pipes from the cats back? I know you won't have the valve to switch back and forth for the stock sound because the muffler will be deleted but you would have the same sound correct?

Will this pass a smog check in California for my 986, 2.7L 2003?

Hi, will the car pass mot with the valves fitted? And can they be wired to a switch inside the car instead of the remote fobs?

I bought a car from these people. The day I collected the handbrake pad retaining springs broke. They couldn't fix it so I drove away in a car with no handbrake. They sent me the parts and I paid a local guy to fit them. He told me the brakes were in a terrible state but in fairness LaRose sent me new pads and discs all round. I did the rears but there was a delay fitting the fronts. When I finally came to fit the fronts I realised they were the wrong ones. I told them but they refuse to change them. So if you want a Porsche with dodgy brakes and like abysmal customer service these guys are the place to go

How much does that cost?
