I plan to install Comptech headers, but before doing so I would like to know the increased noise level of these headers. Are they noisy?

 

No increased noise at all. well may be .2 db's a the most. but you will notice 32 hp.

It's a tad bit louder when you're above 5k rpm but it's barely noticeable.
