first time to be buying muffler only... used to buy the complete cat back systems

so, question, if my header - downpipe is 2inch diameter, but the muffler inlet is 3 inch would there be a problem? -____-

Pretty sure the stock piping is 2.25", if not then someone correct me. The muffler I threw on had a 2.5" inlet and it slid pretty snug over the stock piping, making it easy to weld. If you plan on doing it yourself you will need a reducer unless you weld the sh*t out of it.

 

simply get a short adaptor to weld between the pipe and the muffler inlet.

 

An easier option if you don't have access to welding is get a 2.25 inch pipe with flared out ends. This will allow you to slide the pipe over the existing exhaust. I used exhaust clamps and some exhaust cement and haven't had any leaks yet. Have had this setup for about 1000 miles so far. Make sure you snug the clamps up tight.

 

I've been doing some research on this and your method does work. The only other thing I'd like to mention is that most people suggest using band clamps (see photo) instead of using U-clamps.

This method of joining two ends is very effective especially if you're thinking of replacing a section of piping due to rust damage, cracks, leaks, etc. It also gives the exhaust system a few stress points when it comes to unintentional/abnormal movement through the piping.

I have no experience whatsoever in welding anything so please correct me if I'm wrong or misleading. Just some thoughts I'd like to throw out there...
