I recently did a head/cam/LT install. I have the SLP larger Y pipe and High flow cats with O2 Sensors.These cats are the ones that bolt the the orginal headers. They have the flanges on them. I can post pictures upon request.

These were on an 02 SS 35th LE. The car is not a daily driver.Car has 38,122 miles on it.

2.5" to 3" Y pipe= 150 or BEST OFFER( SLP sales for around 200 new)

Cats Direct Bolt on= 150(Each)Or Best Offer ( the sell for over 200 a piece new)

Dont know how much shipping would be. Prices do not include shipping. Make offer and then i can check on shipping.

I can be reach on my cell as well 770-815-0058.

Thanks, Kenny D
