I just installed shorty headers and werks hi-flo cat. This is on top of the cold air intake, werks ecm tune, and flowmaster 40 muffler. the pipe from the cat to the muffler is still stock.
Before I added the header/cat the flowmaster sounded great. After I installed the header/cat, the car is way way too loud. It also sounds more like a coffee can Honda than ever before.
I am asking anyone for advice on how to reduce the sound without robbing the car of power. I like a nice note, but now the flowmaster is just too much.
Anyone out there have a good exhaust sound with the header/cat combo without using the stock muffler?
Dustin
