About mufflers/cat-back for a 420A

Hi tuners. I have a 97 Eclipse RS and I'm planning on changing the exhaust so I can get a little bit louder. I read a lot about this, and I know that 420A models tend to sound ricer if you do a straight pipe since they are non turbo. Do you guys know a good setup for a muffler/cat-back that sounds great but not ricer? I'm talking about muffler brands that allow the 420A to sound louder without sounding like a fartcan. I also read about using a resonator but I don't have any info on those.

I don’t have any sound clips but when my car was NA still I used an eBay brand catback to get new piping since the stock stuff was falling off and hacked the fart can off and put a borla muffler on. It sounded good without getting raspy like the Honda’s with fart cans sound.

-tsudo rear section

2nd best was
-greddy header
-gutted cat
-custom mid pipe, no resonator
-tsudo rear section

-greddy header
-gutted cat (or resonator test pipe. they sounded about the same)
-aftermarket mid pipe, with resonator

I had a full megan racing exhaust on my 97rs, it was 2.5" after the cat. I would just get something that still muffles the sound a bit and make sure there are no exhaust leaks and it will sound very good. I run a 4g63 now but i also have an affinity for the 420a. Hope you find something good.
