[QUOTE=moondog;11148690]So reading a few past posts. I have a 396 Big Block, 69 Chevelle. Looking to get a complete exhaust system.
From what i gathered the Flowmaster American Thunder Header-Back Exhaust System 1964-1972 GM A-Body V8
Part Number: 389-17119
seems like the popular choice, unless some better suggestions appear.
What's the best choice with headers, i'm basically just dealing with stock engine.
Also do these fit around the stock crossmember ok?[/QUOTE
Moondog- Go to Classic Muscle Car Exhaust.https://classicmusclecarexhaust.com/
They carry complete systems for your Chevelle from Flowmaster, Pypes, and Magnaflow. The 'Exhaust 101' section https://classicmusclecarexhaust.com/i/exhaust-101
gives you a good idea who offers what for your car, and there are videos from FM and MagnaFlow which can help you make a decision. In a nutshell, FM has an H-Pipe in both aluminized and stainless, Pypes has both X-Pipe and True Dual systems in stainless, and both offers their systems without mufflers so you can use what you want. Dynomax and other FM mufflers are also offered by CMCE. MagnaFlow offers an X-Pipe system with their mufflers only, and is a very high quality system. The FM 17119 kit you mentioned comes with Super 40 mufflers, which may or may not be too loud for you. There are more choices for the A-Body than for any other vehicles. There are videos with each of the systems to help you decide. CMCE is currently having a sale and shipping is free. And yes, they fit around your stock crossmember.
