So, i bought i divorce downpipe from ebay and the seller like a goof didn't pack it well so when my friend received it ,It was missing the bolts and gasket im not to worried about the o2 sensor gasket or the one that connects to the flange between the cat or test pipe, I was wondering if i can use the stock ct26 gasket for it.Is anyone running these style downpipe with stock gasket . My buddy whole boguht it from me did a paypal dispute so im impatience to wait another 2 weeks to get the gasket so i was wondering if i can use the stock one.
