Default New Owner Help: CatBack Exhaust and Other Options to Pass Smog in SoCal

Hey,

I want to get an exhaust system, I am a new member of the GSF club. I am thinking of this one or a variant of it (only midpipe or only axleback): https://www.apexi-usa.com/collection...36120891916451

I have heard the sound of this system on YouTube, and I like that it's subtle. I'm looking for a tone that is not much louder than OEM more just accentuating the OEM noise and this seems to fit the bill.

I'm more in favor of stock/sleeper look so the idea of getting a complete catback system sounds like a leap of faith for me. What are peoples' thoughts on this? I've also never really thought of exhaust drone, will it be bad with this system?

Should I get the catback because it'll help with performance and weight and not be too loud? Should I just do the midpipe or axleback? What about keeping the OEM system? I know it's a lot of questions but hopefully the premise of my curiosity is clear. Thanks in advance for any help people can provide

I love everything about the Greddy but I have heard complaints about "howling" sounds at full throttle. Is that true? Any way to remedy?

If you're looking for an OEM+ type sound from an exhaust then I'd recommend the Tom's SS axle back, I have it and it also seems to be the most popular exhaust in general https://www.modinjapan.com/toms-raci...400-tul10.html

Can choose between blue or standard exhaust tips, and later down the line you can always get the compatible Apexi midpipe if you want it to be even louder. I only wish they had an X-pipe version 😔.

Yes, it's true! I took it off and went back to Tanabe.

Recently installed Apexi non-resonated mid and Greddy Axelback. Not sure I have heard the "howling" you speak of. I think the combo sounds great.

Are there any YT examples of the "howling"?

The Greddy system needs an xpipe to perform. That's why you don't have the howling issue.
