2011 starting to get loud, options?

…How many miles are the members getting out of an OEM system? I live in the salt belt ( michigan, state gem is rock salt) so I believe I got my moneys worth. Did some research here and Walker systems are popular. I want a quiet system for sure, as close to OEM as possible. Performance system on a 2.2 is not anything I want to explore. The down pipe will get replace if needed with the 2.4 if its bad. How long will a Walker system last compared to OEM? Any other systems that fit good and keep the noise level down? …
Once upon a time there was GM Performance Parts stainless system that was appropriately sized and would have been perfect, except I have no idea what it costed or when it was discontinued. Don’t know if it was spec’ed for both the 2.2 and 2.4. Bet those answers are buried in these forums. Oh yeah, and someone on Facebook recently found one.

The GMPP exhaust was a Borla item , you can contact them and offer to buy a kit. They retailed for about $650.00 back in the day , I offered $275 and they excepted but refused to ship to Canada.
the system was a little raspy, there are videos still on YouTube. The kit was to be matched up to the GMPP cold air intake kit. 2.4 litre engine.

Maybe a little over a year ago I saw a GMPP exhaust system in the wild (at least that’s what I think it was, have pic somewhere) and the muffler was stamped with a GM part number. Nice basic bl/bl LS. Tried to buy the car. Gotta find those pics. Just found a skinny 1-3/4” supposedly stainless system for $199 at a shady NJ parts site. Didn’t even both to bookmark it.

Its getting a GM manifold on it. Told the mechanic that Im not in a hurry for it, I have another vehicle to drive. It should be done today. The only exhaust work I like to do is headers on a V-8 classic car with all new system. He was familiar with the hhr system and wasnt too happy with the Dorman replacement manifold.
