Those are pretty big numbers for a 2.7 Liter WOW!!

I guess to each is own on the Exhaust being too loud for you though ,I have a rumus exhaust and my friend has a Borla on his Cayman and they both make the car come alive IMO. My only complaint is that they are both NOT LOUD ENOUGH!!!! Pure music to my ears and the drone thing is over blown IMO. You can control the drone to NO DRONE pretty easy.

But I am glad you found your OWN way to make your car more enjoyable . I am going to look into maybe getting these NHP headers will they fit a 2007 Cayman? Thanks and Great Post

 

Good looking product

 

I went with the NHP "catless" race headers for the Cayman on my 986 - no dyno numbers yet

 

Hello and Peter actually did flash with Softronic and is VERY happy. I believe he posted it on this site in another section.

I do appreciate your support also .

Hello,

I am looking for a Tubi new/used for my car.

It is a 1999 C-4 na Tip.

Anyone with this system/mufflers please contact me.

Thank You.

 

Does anybody have any experience with FVD Brombacher 'Sound' mufflers/exhaust? Another forum has had good comments about the sound, and supposedly no drone. Dansk has a similar muffler with tips that resemble the early PSE, but it is quieter.
Thanks.

 

Did any of you have P0430 error codes when you installed your NHP CATS ? ALso these cats have 3 ports for the O2 sensor one pre and two post. Which hole on the post did you use for your O2 sensor the one on the cat or the one just passed it. I will on accation get this damn check engine light with P0430 code and I am just wondering if I have a bad O2 sensor or should I just try and move the sensor to the other hole

 

i have nph headers and cats and have cel with codes of p1090, p1175, anybody have suggestions.
