Couple of ?s

So I got some hedman long tube headers with a o/r h-pipe no cats
What mufflers do I need for a nice rumbling sound.?
Also my timing is the stock one
Do I advance it.?
What should my spark plug gap be.?
Should I do the tune up before or after the headers go in.?
Thnx in advance

I like the flow master 10s, good tone and just loud enough. I would go ahead and do a tuneup if its been a while since the last one. Factory spark plug gap is .54, and I would advance the timing to around 13-14* advance but make sure you have 91 or 93 octane gas in the car before you do that.

I have regular 10s, I don't know if there's really a significant difference between them and the super 10s.

They're both stainless, all I really know is the 10s are delta flow. Not sure about the supers.

I have flow master 10's on mine with h pipe and 3im dumps. Sounds great on idle and just comes alive at higher rpm. Very good choice. I'm wanting Borla with SVO side skirts though (later down the road)

I'm not surprised but why hasn't anyone said Magnaflow Magnapacks or Magnaflow bullets? Or Dynomax Bullets? They're more expensive than Flows but they're definitely deep and "rumbly." I will say tho, I've got Magnaflow bullets dumped with an o/r X and its deafening and bone shaking. If avoidable, don't do dumps
