Hey guys, just bought an HHR SS last week. I'm so gung ho for modding it that I've decided to say to hell with the warranty and do some mods. So my question is, does anyone know where I can find a good catless downpipe? It has the GMPP stage 1 kit already and what I beleive to be a GMPP cat-back. I am also looking into adding an aftermarket intercooler/piping and bov. Any suggestions for any of these parts?

 

You've got lots of options there. Before anyone else chimes in: try doing a search on here for catless DP and intercooler and you'll come across a host of threads on different brands. Also in case you're not aware, most parts that will fit on the Cobalt SS/TC fit out HHR SS too since it's the same platform in essence. I have Hahn's catback exhaust, intercooler, and (soon to be installed) IC piping on mine. They're the most expensive, but the quality's top notch. Their customer service, ehh could be better lol. Again, try searching on here and if you don't find what you're looking for come back to us. Welcome to the site and enjoy!!

ok, just got my baby back from a clutch replacement. it only took a month lol. I had the guy doing the clutch fab me a downpipe and I must say I am impressed. 3" downpipe with the 3" gmpp catback sounds awesome! Thanks to Go Fast Racing in pinellas county Florida. had to give some props.

 

i didn't know gmpp made an exhaust for the ss
