That's the natural sound the engine makes. You can use a resonator to eliminate most of it. Probably only $50 bucks total installed.

A cat will quiet things down by restricting your flow, but a resonator is better because it won't restrict your flow, just filter out the high frequencies through geometry and the way sound waves behave.
Sim on the downpipe? I'm not sure what you mean.

Do you have the 1st or 2nd gen EF exhaust? The 1st with that huge ass fartcan can be loud as hell and raspy to boot. The 2nd is pretty mild and the only drone I ever get out of it is at a constant highway speed, but even then, it's tolerable.

The flex pipe? Do you have a huge round stupid looking muffler on the end, or a normal looking oval one?
