Does anyone have anything good or bad to say about the Ravin mufflers? Should I go with the 33 series or 55 series?
No comment, my favorite is Dynomax.
Should I go with 2", 2 1/4", or 2 1/2"?
2.25" is perfect for street use, neither to small or too big and does not present any problems for professional installer.
I don't think I need the 3".
Fine for a 454 Chevy truck! Don't need or want it on a 302 sb Ford street driven. Too big can cause problems too.
Should I go with a mail order exhaust system.
No. Professional muffler shop can do a lot better job, a lot quicker and for generally the same cost.
Should I have an equalizer pipe welded in?
Your choice. There's a lot of debate on the benefits. Some say it provides a more mellow exhaust tone which is likely to be the only benefit for a street car.
Sorry for all of the questions, I'm new to this.
