Very curious to know what's the best NA header for Kseries ? I know and understand most if not all elminate the cat, but in case like that how's the O2 taken care for emissions perposes and check engine light stays off possible bong adapter ? For O2...... And if possible is the noise level reasonale for daily driver ? Thanks....

 

bong adapter? ummm... you need to put down the bong son



but in all seriousness... Hytech, ASP (www.advancedstreetperformance.com) SMSP, Burns

 

I vote ASP. The exhaust you run will play more of a factor on how loud your car is in my opinion. You could run the hytech twin loop setup but it's $$$$ and only comes in 2.5".

 

I vote ASP also Stefan builds headers to match your setup

 

Best off the shelf header or best header fab shop??

 

yea get a $1000 header.............

 

DTR header. they have a few 9 and 10 sec all motor k series whip.
