Circuit werks delete pipes

[oc-boxster]

I was looking on ebay for some secondary cat delete pipes. The only ones listed are by circuit werks and they look slightly different from the fabspeed or topspeed pipes-does anyone have any experience with the circuit werks pipes? I have my name on the list for the next batch of topspeed pipes but I'm getting impatient.

Interested to see how they sound compared to the Topspeed ones. Are you planning on a new muffler too or just the cat delete? I tried just the Topspeed cat delete alone but didn't notice an increase in noise.

If you do go with Circuit Werks, please post a clip. Or maybe I'll see you at an OC event.

I probably will keep stock muffler. Just want to cut some weight and maybe change the tone a bit-I've heard other than mKing the car louder aftermarket exhausts really don't add any HP or torque.

I have them - went in easy and have had no problems. I have aftermarket exhaust, these pipes made it quite a bit louder under throttle. Also did 160 t-stat and 4" UD pulley at same time, but the car certainly pulls harder now.
