Looking at doing my own exhaust just wondering which magnaflow muffler would be a better choice. I like the Magnaflow #14829 muffler and I've also liked the #11216. I know this sounds dumb but I'm not to sure what the stock piping is on my car. Obviously I have a 2.4 eco it's in a 06 ss sedan. Idk what the biggest difference in em since some are more then others. I'm looking something with a nice deep tone and I'm not looking for a quiet exhaust. I'd like to beable to hear it, lol

 

I would go with a 2.5 inch inlet/outlet muffler . Also if your doing a custom exhaust which is what I did myself I would suggest you replace the stock piping that shrinks down to 2.25 at the rear axel. I bought this product here:

CTI 2.5 Over Axel Replacement for after market muffler - Over The Top Performance

 

^ this...my Magnaflow catback came with 2.5" piping

 

So is the rest of the exhaust 2.5 before the rear axle then?

 

Yes thats correct. after you do your custom exhaust you should also add a intake, header and downpipe to get your car breathing even better.

 

That's odd for them to take down the exhaust size like that. Thanks for the info. And yeah I plan on getting a header n intake just waiting for the little extra cash flow.

 

Yeah I know I thought the same thing when I found that out myself. But thats GM for ya they don't always do everything correct or for any logical reason lol. No problem man any other question you have feel free to ask me.
