I'll be able to provide feedback on how the Graziano feels with my Coyote SLC as well. Shortly. Car is at the dyno now getting re-mapped to support the intake changes, etc.
Hi Dean. Regarding your comment below:
"The option of using a real muffler and giving up the x pipe is always there but why would I ever want to do that?"
The answer would be take a ride in my car! I have the same setup, possibly bigger Burns mufflers, and when I drive on interstates for any length of time I use earplugs! Yep it all gets to much after a while. Its great for short 30 minute drives but any longer and hell its loud.
Anyhow we will see how you go.
This is one badass car and I want it to sound like it. Every builder is different. Who wants to hear a lion "meow"! Roar baby roar!
