Never Mind they are very nice , very quiet inside the car but have a great rumble outside!

I've been thinking about getting these, Can you give a comaprison to some other mufflers?

 

[whitey5oh]

Maybe Spintech, but i dont know really , it truly has a unique sound, you'll love how quiet it is inside your car. but it is kinda loud outside, they are in my opinion, near perfect.

I just ordered a Moroso Spiral Flow muffler this morning. It's good to know that they aren't loud inside. Now I can't wait to hear it........

Whitey5oh, do you have cats in front of the mufflers?

Thanks, Whitey, better late than never.
I put the Moroso on my Bronco with a 351M and single exhaust. Man, was it LOUD. I looked for a resonator to tone it down a bit, and settled on an IMCO single chamber (Flowmaster clone). I attached the IMCO directly behind the Moroso, then ran the tailpipe out behind the rear tire.

This setup gives me a deep, aggressive tone outside the vehicle, but quietened it down inside the cab. Just about perfect.

The Moroso is advertised to flow better than an open pipe, and I believe it. My SOTP dyno shows more torque on the low end; it's a very good muffler in my opinion.
