I ordered the fabspeed muffler bypass pipe for my C2S.

What is good/bad things about?

How loud are these?

Is it illegal for driving with them in Philadelphia?

Thanks in advance.

They are crazy loud.

Almost everyone that tries them ends up getting rid of them after a while.

The main thing is the mind numbing resonance in the cabin. I used to wear ear plugs on my way to Sebring or Homestead and i still got a headache.

But the car does sound awesome. Dont know about sound laws in PA.

Installed fabspeed cat bypass pipes on my '97 993 today. They are scary loud under accelleration. The muffler guy laughed his *** off when I drove away...And I already got the evil eye from my neighbor.

Could have bought the same thing on Ebay for $100..... saving you $400.

Everyone will turn around to look at you. I have put them on two separate occasions and tell myself both times I will never put them back on; take it however!

I installed a set on my 997 and it transformed the car. Great noise and definitely bearable. Faster but fuel consumption goes up. I saved myself $7k in replacement cats!
