Wondering if anyone had a review on the scp di/do resonators used with borla pro xs or any other mufflers. Thanks
 
Yes, it's just a resonator it can be used with any true dual exhaust setup for the 2.5 in. Resonators help keep that ricey sound out of your exhaust.
 
well it is listed as a muffler but some have used it successfully in place of the res...this is basically the gist:

"Difference between muffler and resonator
A resonator (helmholtz resonator) uses a tuned cavity to actually actively cancel out sound. It creates a band-pass filter that eliminates problem frequencies - so they tune it for a specific loud spot in engine operation. It targets only a small range of frequencies.

A muffler is usually a series of expansions that take energy from the gas flow to decrease sound. Sometimes they have resonating chambers built in, but typically they operate on a purely expansive vane - expanding a gas so many times into such a volume muffles certain frequencies.

Basically, in the real world, with a resonator you'll be able to quiet specific exhaust notes - usually targeted to a cruise RPM to cancel that frequency, but you'll still have a lot of harshness from the high frequencies the resonator passes, which a muffler will cut out.

The good thing with resonators is that they usually have zero flow restriction, so adding them to quiet an existing setup will cost no power.

So to answer your question - they work best together, but if you were to have only one, I would go with a muffler - it will kill the harsh notes, even if its not specifically targeted for the engine note." (thekingofazle, fordmuscleforums.com, feb 28 2007)
