I bought these a couple months ago and put about 500 miles on them. Then decided to send my Z to s and r performance for a turbo kit. They have 3/8 fittings tig welded on both sides of them for egt sensors and a wide band bung on left side. I paid 400 for them they are for sale for 300 obo. All low ball bids will be ignored.
