so whats the difference from the gmpp/borla and the normal borla for HHR on their website? it shows on those websites you just posted that its made of just 'stainless steel' as compared to the borla website the $800-900 version says t304

 

and its $396 on borla?? when all gm parts websites have it for 600+

 

t304 is stainless steel

You now have all the info you need to make an informed decision.

The only difference is logo's and part numbers.
If your concerned about a possible warrenty issue, you might want the GMPP stuff on your HHR, but other than that...spend wisely

I hope this helps

 

there are different grades of stainless, the borla is t304..the magnaflow is t404...the gmpp/borla just says "stainless"..
the CGS and gibson exhausts are crappier stainless steel and start to acrtually rust and the quality is not there compared to the magna and borla...im just hoping that borla didnt cut corners to make the gmpp

 

I may have mentioned it to you already, but I put the supercharged cobalt exhaust on, only $50 and it flows and sounds much better.

 

cat back or just muffler

 

that's a sweet price from Borla

 

I got a used ss/sc catback, pipe diameter is much bigger and muffler less restrictive. Tip needed to be shortened though, and one rear hanger is different so bent it down a bit.
