Any 200cpsi is going to be louder than a 400cpsi
also a GESI cat removes more particulate than a non GESI cat If it cleans more expect less sound would be my guess.
Take a look at this. It has some good info

Yeah the factory cat is pretty robust for a 4 cyl. It takes alot of noise away.
I attached the top heat shield. The lower one was not retained and I did not wrap. My IATs havenāt been an issue and I donāt track the car. Jester did a ton of data logging on my car and everything was...
Iām running a @Jester04 tune now. I had a TSP tune when I first got my Hondata.

Ok this is going to piss some people off but,
MAP advertises a GESI cat. They come with a cheap 200 cell cat and you WILL get a CEL.

I put the 5.25s in the rear doors and kept the stock tweeters. They are 4 ohm in the rear doors iirc. Fit them into the factory housing. Clean and easy
Yeah I posted a while ago in the what did you do today thread about it. I added some aftermarket ones. Used an adapter wire pigtail. Works well. Much louder. And added a little color. At least people hear me when I lay on the horn now.
Jester tune is the way. I have about 2k miles on the tune and we have been through a few revisions to get it dialed in perfectly and you canāt ask for a better tune. The attention to detail he brings to the table is top notch. 1000x recommend
I did some Amazon horns. Much louder. Fraction of the cost Did have to make the mounting hole a little bigger on the horn adapter and had to get a 2 horn adaptor but easy as pie
