what do you guys think

so i had my exhaust done last week on the wagon. yesterday when i started the car i noticed that it sounded like the exhause hit my torsion bar, then when it started there was a leak at the collector. i was in a bit of a hurry so i figured i would tighten it up later. well i got on the freeway and the whole gasket blew out which led to the exhaust flopping around hitting my torsion bar. i looked underneith and the only place he supported the system is at the mufflers. it looks like there needs to be another support up by the transmission maybe. later that day i tightend it up and it wasnt so bad. it still leaked since there wasnt a gasket, but it wasnt flopping around. well this morning im driving over to my dads and the other header blows the gasket out and now my exhaust is flopping around and hitting my transmission. he said it had a 2 year warranty. it didnt even last two weeks! so im pretty pissed off at the moment. and i will be waiting outside the shop with my car tomorrow morning to have him fix it right. why cant anyone just do a good job anymore. i mean i dont do exhaust. but it seems like there is alot of stress on the headers because there is no supports. what do you guys think of this.
