What’s the best “flowing” dual tip muffler available.? I really want to keep two tips, but know an HKS Ti for example will perform best (better), I think. Appreciate any input

Want to keeps this

But need this

 

St Mays Shotgun or Apex'i N1 Duals are the 1st couple that come to my mind.

Both are ear shatteringly loud. The trade off is exhaust flow or neighbors. Which is more important?

 

ha ha, thanks for info, I’ll do some research now.. Neighbors already hate other loud car(s), just a new “tone”, I’m sure they’ll love

 

I love how the N1 Duals look but I hate how the volume ==> uber uber loud with DP and resonated MP (Borla XR-1) even with the silencers in place. I have had guys on Harleys complain it is too loud.

Benefits are the dual flames shoot out the tips, and the shotgun volume blasts that accompany the flames.

The N1 duals will be replaced this season with the Tanabe Medalion Touring Exhaust.

If you can accept a very loud, obnoxious sounding exhaust go for the N1 Duals, I think they look fantastic.

 

Probably RB Duals.

I do have to disagree with the_saint, N1 Duals are the WORST exhaust ever made for an FD. Doesn't sound good, fits poorly, will melt your bumper, and just sounds like LOUD, not "loud good", just dumb.

I've heard good things on the St. May Shotgun, never heard it in person. That is RARE at this point.

Most any exhaust will not be THAT loud with the stock cat/twin turbos. When you go mid pipe or single/nonsequential that's when things get crazy loud.

Chris @ RP in Garland hates the N1 Duals as well for what it's worth. He says they fit like **** and can damage your car.

 

These look good, maybe a bit better flow/less conservative that the RB dual:

Dale and @c0rbin9

My N1 Duals fit perfectly and have not had issues with melting the bumper.

Agree on the sound being 2 thumbs down.
But agree on them having to go. I never had them with the stock MP or DP so they have always been loud. Had them with the stock turbos, and then later with a GT35. They definitely got louder with the GT35.

Look elsewhere.
