re: headers.

i have had my x-force headers on for about two years. They were ceramic coated just on the outside and were wrapped correctly, ie each pipe individually.

Just last week the small bracket holding the slip joins broke and as a result under full power they must have shifted and came apart somewhat. (Car was Sooo loud!!)

Bracket has been re-welded and a tack put on the offending slip join and all is well.

The performance gain from headers is real, alot depends on the design as well as Dan said from the post on REXNET....When they are hot, part-throttle response from 2500 to 4000rpm is significently better than stock manifold, in higher power applications the mid and top-end is better also.

X-force are a china copy of SYMS headers, a good design. The quality of the steel cannot be guaranteed. The cost of coating needs to be considered, allow 300$, the cost of wrapping can be 150$ in materials and upto 200-300$ in labour if you don't do it yourself. Add the cost of a re-tune as well....
