FABSPEED MOTORSPORT | GT4 Race and Sport Headers
#47
I think with the fabspeed headers and exhaust ibd plenum and throttle body and Cobb tune tying it all together 0-60 in 3.5 secs and a 12 sec 1/4 of a mile for the Spyder is a definite possibility
#48
So I just can bolt these on? No CEL no nothing?
#49
How do these compare to what cargraphic is selling?

fabspeed says we can use the sport headers (not the race) with the exhaust and we should be fine. However.. says the cobb smooths it out and adds a few hp and tq on top of it all. I'm waiting for their upcoming dyno runs with all three items.
I wonder if they could do a dyno then adding the TB and plenum on top of it all to show the incremental gains.
No idea how these compare to Cargraphic.

I hate catalytic converters, they are $$$, clog over time, and rob power. I never run them on my modded cars. But who knows how many of my brain cells I've killed or whatever risk I run of getting cancer.

How do you pass emissions. do you get special software from VW lol

Race Director
it's quite easy to remove exhaust and headers on this car actually. even assuming you have to pass emissions every year.. it's worth it to run it like you want to, and then reverse a few mods 1/year.

my mistake. thanks for the correction. makes the cobb even more interesting.. can't wait to see what it does for the curves over and above the already amazing header/exhaust setup

It's true that we experienced no check engine light during 300 miles of testing. Your results may vary, every car is different.
The Accessport will do wonders with a full bolt on GT4, we look forward to tuning in house and providing more information as soon as possible.
