Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.
Equal-length performance headers improve exhaust flow and sports car sound; Sport Headers include 200-cell HJS Sport Catalytic Converters.
INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.
DISCLAIMER: This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product contains a High-Flow Sport Catalytic Converter solely intended for track and race cars as it is NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.
I was running the supercup exhaust system with my OEM headers and thought the sound couldn't get better. But these headers give my 2002 Porsche Boxster a deeper more tuned sound at both idle and while driving, with these headers you can also feel a little more power!!!
I buy my 986 headers with cat and install! I love. Very happy. John Gaydos at Fabspeed do very nice job, car sound amazing!
I'm just thrilled with the Fabspeed Headers...they arrived several days ago at European Auto Garage and Marc did the installation yesterday. The Headers add a mellow sound to the exhaust note and allow the MY96 2.7 ltr engine in my 04 986 Boxster to rev more freely with noticeable mid-range and beyond torque. Again...I'd like to Thank You for your assistance and say that you have a Very Satisfied customer.
My 1st Impressions were the Quality of the headers was nothing short of a work of art ,the welds were so perfect you could hardley see them .They have a very nice looking consistency throughout.As a previous welder myself I was awe struck at the overall quality and attention to detail .Now I can see why these headers are so sought after ,they are worth every penny IMO1st Impression starting the car -WOW!!! is this my car ? AMAZING SOUND!
Gone is the lower pitch sound the Remus has by itself and replaced by a slightly higher pitchey sound .A more race car sound with a real punch in it .
When you punch it and hit 4000 RPM is is just SICK!! likie a Indy car or something .WOW!! you have to hear it in person to believe it and appreciate the sound ,the videos I have heard do not do it justice IMO .
1st Impression driving -UNBELIEVABE DIFFERENCE in the Sound ,Tourque and HP .My car feels like it has over 300HP and the Tourque is just amazing ,the car pulls after 3500 to Redline RPM like a mad dog now! .
Anyone looking to really UNLEASH the power of your Cayman and staying naturally aspirated this is a great way to go. You wont be dissipointed I asure you .Fabspeed Headers -worth every penny spent .The only problem I see is people might think I some overly happy person cause of the permanent grin I have on my face when I am driving
