I'm new to these forums, but I have some experience in the DSMTuners/DSMTalk forums and from the scene. Short story is, I bought a 2003 Lancer OZ Rally. Its a nice little car, it has a little pep to it and has great gas mileage which I need since school is a good 50 miles away. As any teenager, I was looking at exhausts, headers, and what not through the forum. I never did find my question.

I was thinking of a 2.25" pipe from the cat, to a Megan Muffler. The problem is, I normally buy full exhausts (Was thinking of SRS). I don't know if they come with a flange on the end, or just a opening to it. If the Muffler has a inlet to it, do I have the exhaust shop weld the 2.25" over the inlet, or do I have them put the the pipe inside the inlet a bit...or have them somehow match of the piping and weld the line.

Sorry for the bore, but loving the site and thanks for any feedback! Good or Bad

 

What comes with a flange on the end of where?

you talking about where the exhaust connects to D in this photograph below?

 

When my brother made his system, he bought a HKS Muffler, and the inlet had a little length with a flange. But yes, I am talking about the inlet (D) in that picture. Do you put the pipe inside it, or stick the inlet inside the exhaust pipe?

 

Neither?

The muffler comes with a pipe welded to its inlet that goes about 1 or 2 feet then attaches to a flange

I really don't understand what you are trying to say though

 

i would get a Magnaflow muffler the stock piping is fine it wont make a big difference

 

If you have a set of welding clamps and some work area to make it easy, clamp them together so they touch and tack weld it in place. Then remove the clamp and complete the weld all around. Just as strong as solid pipe. Pain in the ****, but if that's what you got to work with, go for it.
