For a 1970 SS 396 with headers is the Magnaflow correct part number 15894?
Can I use my old collectors?That's what Magna Flow says. You could always call them and check if they have other options. I installed Flowmaster 3 inch over the axles, and while they fit, they were not all that great. My exhaust guy did some rebending to get them perfect and symmetrical.

You'll need the collectors for your specific headers.
The Street Series Stainless Performance Exhaust system delivers dyno proven power with a comfortable interior sound and performance exterior sound.www.magnaflow.com
What system do you have, size exhaust, engine size and do you like the sound? Looking for sound clip.I can tell you about both, as I was a manufacture’s representative for both companies at different times. Both do not come with header collectors. You can pick up collectors that fit your headers then have them welded to the system (cutting will be required). Magnaflow uses an X pipe, while Flowmaster uses an H pipe. Magnaflow mufflers are polished Stainless steel as Flowmaster‘s are painted Stainless. Biggest difference is Magnaflow system exits straight out under the rear valance so you can run O.E. Style chrome tips. Flowmaster’s rear pipes have a slight down turn, not allowing the use of original style tips. I hope this helps! FYI: I have a Magnaflow system on my Chevelle!
Very nice. At the moment I am on the fence as to should I replace a perfectly good aluminum X pipe set up with just mufflers or go the whole way with a complete SS system which in the end will be costly.
