I'm planning on doing a true dual setup on my car and I'm gonna run some Moroso spiral flows. I need it to be as quiet as I can so I'll prolly throw in another pair of bullets(dynomax or something similar). My question is would there likely be a difference in sound by switching which mufflers I install first? I would probably have 1 set in front of the axles and the other pair in back.

I'd put the regular bullet mufflers before the axle tubes, and the spiral flows out back. Mainly for the fact the regular bullets have the least amount of flow restriction.
Have you considered just running 2 spiral flows per side?
That would be quieter.

If you want quiet dont go with true duals, just doesnt make sense to have to run multiple mufflers to "try" and quiet it down

Hmm, no I hadn't thought of that. That could be a good idea

Are you going over or under the axle? Since you're having it go all the way out the back and are not dumping it, you should be able to put a normal sized muffler in the stock location out back. The magnaflows are pretty quiet.

Use short bullets up front ,then use the longer bullet in back. I think they're 18' long.
