The motor is a 2004 GTO with medium length headers, no emissions and stock cam. The plan is to take it from the collectors to 2.5" pipes to a Y and out with a single 3".
What I would like is a good sound without being too loud, this is a daily driver. The muffler that is planned is a Borla turbo with an offset in and center out.
Would a single muffler out back be enough to quiet it down or should I use a mid muffler? Both would be straight through design.
This is what it sounds like with open headers:

Did the same for my LS6 wrangler. 2.5" into an flow master merge into a 3" Flow master 3" the back of the wrangler. First flow master was delta 50 and t was bit loud. More than bit. Changed it out to 70 series and bbbiiiggg improvement.

So, you used a single muffler. How loud would you describe the 70 series muffler? Do you see any need for an additional mid muffler?

For singles the only muff I like that flows well, sounds mean, but most importantly has NO DRONE is the Hooker Aerochamber. Plus as a side bonus they are pretty well priced.

On the Jeep it has good sound. No drone to speak of but that 70 series is big.

I don't see a need for mid muffler. The 3" 70 series is 3" all the way thru. Not 2.5" with the ends expanded like some 3" mufflers.

Thanks, that is what I need to know. No need to buy two mufflers if one will do the job. It doesn't need to be whisper quiet. I don't want to be obnoxiously loud and I have no point of referrence.
