tti 3" exhaust (UPDATED)

Nice job on the install. TTi is great in my book. If you add a short section of pipe with an oval megaphone shaped end to the end of the cutouts, it will sweeten up and enhance the sound. It works much the same as the flared end of wind instruments. I did the same thing to a buddy's car and it really made a nice improvement in the sound of the open exhaust. Here's a pic from my 1970 e-body.
