I have been doing some searches on here looking for part numbers for Magnaflow mufflers that could be an easy replacement for the stock muffler. It appears that some have done this mod, but I can't seem to find a part number for the muffler that some have used. Any ideas? Thanks!

Do a search for "magnaflow muffler". One was just sold in the classified section too.

I did this and still did not come up with measurements or a part number. Just to clarifiy, I would only want the muffler, not the cat-back system. Thanks!

 

Here are some Internet resources which are available in the original part numbers.

Russian site, but pretty easy (use a translator Google). Lack - HHR only from 2008 to 2010

this resource in English. You can look through the identification number (VIN). But I did not used it.

I'd just get a generic Magnaflow and have a shop fab up a muffler for you. I did that on my last car, and was very happy with it. It was about $180, I think, and that was a 2.5" setup.

 

I saw that - after it was gone. It was local, too...

I would do the Magnaflow again, but I'm in a money pinch anyway till I sell my old car and its parts that are filling my garage.

 

I did the custom with duals spent about 500 getting R done

 

Does anyone have the measurements of a good replacement muffler? I would like to order the parts online and then bring them to a muffler shop. Thanks guys.

There is lots of room I picked some that were 18"x 9" there was lots of room. When these wear out I will switch to higher quality tips,keeping these clean takes work, found using clay bar with metal polish works great.

 

I went with the Imco T-910 ordered thru Midas total muffler and installion $90.00 Im happy with it.
