DPT Motorsport Exhaust Headers

So, the exhaust headers on my 97 4.0 cracked and needed replacement. I ordered DPT Motorsport replacement headers off ebay for $140. They bolted up fine, but one of the tubes (2nd from the rear) was too high and wouldn't let the intake manifold sit flush. Solution: cut a piece out of the intake. Questions? Comments?

Update: I didn't catch it at first, but one of the header tubes were also touching the motor mount, probably causing my unexpected exhaust leak. I used a metal grinder to give the two some room.

Might want to start looking for a new intake manifold.. Shouldn't have needed to use a grinder to cut pieces.

The integrity of the intake manifold has been maintained, and the small amount of metal I took off of the motor mount was trivial. I'm mostly posting just to get the word out about my challenges with the brand so others can avoid the same issues.

Solid headers, but fitment and the alignment on to the rest of the stock exhaust piping was in no way a correct fit. For the time I spent correcting issues, I would have gone with another company.
