Thanks. Seems like the way to go for me! Do u just cut the pipe or also have to remove the flap ?

Once you cut the pipe, nothing needs to flow through the flap.

Wtf called few muffler places and no one willing to do it? Everyone said to get a new muffler instead and said I'm wasting time and money. Geez it's my time and money... Is it hard to get something done even if u have the money?

Even a mechanic familiar with welding can do this, as is a very simple mod.

I got it done for $70 cash.
