This is my set up for the streets! 3" Mandrel bent pipes from the headers right though to tail the pipe, twin into single Y piece, 1 big Lukey muffler before the diff. $700 bucks the lot installed!!
The Redback muffler!
Sounds great at idle and good when ya keep the revs low but when I get up her it gives resonating buzz which is a little annoying, but no drone! The sound changes when I go from my Shaker to air cleaners (which is crazy but true), unfortunately it has better sound without the Shaker on. The first muffler was a red back straight though and it was horrible!(pic above) The Lukey improved it a fair bit but still has that slight resonating buzz, and it restricted a bit of power! I still I ran 388 rwhp on the dyno with this exhaust!
So that's my street set up but now I'm going to build a side pipe for racing so that will be interesting! I'm going to kick a 3" pipe after the Y piece (so I don't need to invest in a crossover) out to the side of the car under the passenger back door with a straight through muffler of some type, and set it up both systems so I can bolt and unbolt them for what i'm using the car for.
With the redback muffler and not tuned up!
And with the with the Lukey muffler and tuned up but not dyno tuned!
