A couple of months after I bought my 2010 SS/TC abaout 3 yearas ago I ordered all my parts from Hahn. I got catless downpipe, exhaust, Intake, intercooler, intercooler pipng and the PPC tuner. To be quick the downpipe is great no cel even catless. Exhaust has rattled since day one looked ito in couldn't fix but sounds great. All my piping is starting to rust and the 3 bar sensor doesn't fit the cold pipe. They sold me the PPC tuner to go with all the parts and the maf trims were so terrible I had to run meth to get rid of all the knock the tuner was the worst thing I have ever spent money on for any car was totally misinformed when buying it and Hahn knew I was getting all their parts. and no this happened to my intercooler.



Crazy boost leak from it being split. I've never done a negative review before but with all my parts other than one having problems I though I'd voice my experiences

 

Sorry for your bad luck, I hear mixed reviews about hahn.

 

Havent had 1 problem from hahn. But I did buy my stuff around the time I bought my car in 09. when they were in plainfield Illinois..
