Mine leaked right away, hydraulic lock and bent rods. How much does that cost? Seller said that it was not his problem and you could not get blood out of a turnip… XSpower hung up the phone when I explained the problem, tried calling back, goes straight to voice mail. During my conversation with the seller (FTG Motorsports) he stated that he had had 30% of the one’s that he had sold have the same problem, also stated that he has removed from web page, just checked, they are still for sale on his page. Don’t EVEN think about buying these headers, spread the word, don’t want anyone else to get burned.
