What size are the header tubes? 1 5/8", 1 1/2", or 1 7/8"?

John@Fabspeed

Our Headers use 1.75" tubing/
Let me know if you have any other questions.

I ordered a complete system with headers, heat and cats yesterday. I am told the cats are 200 cell sport cats. I figure this will be the best of both worlds. I have installed the maxflo mufflers in my 997 and been very happy with the weight savings and sound. The fit and finish was excellent. Even though I have always though the non-cat 911/964/993 Fabspeed exhaust system was not too loud I think the system with cats will really make my wife happy. Since I like to take my car on long drives it should really quiet down the sound in the cabin thus lowering driver fatigue. With the cats I am sure the car will make it past smog here in california. Will keep you guys updated.
