Anybody use Pypes X pipe

I put one on my 70 dart. The only problem I really had was with the tail pipes. They advertise that you can use stock type tips. Mine didn't fit too well. Sent them pictures and they said the wrong tailpipes must have been in the box, so they sent me a new set no charge. have not put them on yet, but they appear to be the same that are on it and probably won't work the way I want without some altering.
