Casting quality was poor at best, unusable on my corvette In my opinion, tried grinding and cleaning up casting but decided easier to buy better pair .
I used this product on my 79 corvette to put on side pipes worked very well with no clearance issues like I was having with 2 different styles of headers.
Quality product.
Good price good fit
Bought a set of exhaust headers that was missing a part and the service team responded quickly with a replacement. The price was the best I could find also! I will use this company for future online buys as needed. Thanks for the help! Marty A.
i was very happy with the items i purchased, delivery was quick-the price was fair and i will do business with this company again.
