If you get the fabspeed...DONT use the OEM clamps...spend the $35 and get their clamps for piece of mind. With the heating/cooling expanding/contracting...their clamps are a perfect fit.

 

So this will delete the cats? Do i need O2 sims?

 

It deletes the mufflers. (Hence the name muffler bypass)

 

What do i need to do if i wanna delete the cats? sry if im hijackin the thread

 

Deleting the cats in an N/A 996 will cause CEL's and make the car sound like crap. A buddy of mine had Cargraphic mufflers, Suncoast Headers and cat bypasses and it was the most horrible noise I have ever heard. Cat bypasses removed and it sounds fine. The muffler bypass sound is very nice IMO.

 

Alright, thanks for yor help man

 

Another quick question, should i still get sum if I already have B&B headers/exhaust. Would it still sound good? Will it still fit? thanks again

 

They should work as long as you have the stock cats. You will be completely removing the mufflers and putting these straigh pipes from the cats back. I think it will still sound good. (might be a bit loud though)

 

i love the sound of mine & they are not as loud as I originally thought cuz I got used to em. No CEL here.
