What do you mean "compare"?

All exhaust systems are going to be about the same when it come to HP gains (if any). The MS exhaust doesn't have bigger tips like the Borla or Greddy.

So you've got to answer two questions:

How much do you want to spend?

How loud do you want it?

How much each costs is easy to find. How each sounds is the challenge.

Cost does not matter. Sound Not like a 1992 Civic Hatchback kinda like my old camaro ss. I no i wound get that sound but like it

I'm the same way. The cost doesn't matter as long as I liked the sound of it. However, I don't necessarily trust the sound clips people post only because IMO it will more than likely sound different in person. (The sound clips were not made under the same conditions.) Again, the challenge of buying an exhaust is hearing them "live and in person" to help you make your decision.
