I was looking to buy one of these, I'm currently just going to install the muffler.

I have a friend who works on cars all the time and can weld it no problem but how should I go about doing this?

The stock exhaust comes in at about a 45 degree angle, while the magnaflow is center inlet.. should I push the magnaflow out slightly and we will weld a elbow type fitting in between?

 

You gotta cut the piping before the muffler and make a replacement so you'll have more space to play with.

Also don't forget to install or weld a hanger. Don't want your exhaust to be hanging and dangling like a Honda.
