Exhaust solution

[m3fool]

Hello group good to be back on a forum, been years

Sorry ….it’s a exhaust question(s)

I recently upgraded to megan racing headers and the rest is stock. First car I have gone catless with. Of course tuned the car and I expected it to be smelly but at times it feels very strong in the cabin and also with the ac on.. exhaust leak? And with the rasp increasing I have been thinking about resonated sec 1 or 2. I know everyone always does sec 1 typically but what is it like to leave sec 1 and only change sec 2?

Happened to find this deal, seems suspiciously cheap, wondering if this is good brand and about the sound ?
Apologies ahead as I’m not sure about forum rules if we can post links..

You removed the only thing that cleans the exhaust on your car and now you're wondering why it's "smelly"?

^Have you seen my name?

Just how catless cars are, I used to smell it on my clothing for hours/days after.

Once you have the nose for it you can tell who's catless at meets/cruises too lol.

Make sure you turn recirculation on but other than, there should be no smell with the windows up. There's a good chance there's actually a leak.

^ thank you that’s what I was trying to find out . The cars been catless since Jan so I’m used to it and can handle it with windows down but it’s annoying to still smell it with window up so I’ll just go ahead and upgrade. Any opinions welcome on the DNA motoring brand… ?

Catless is a real man's cologne

You don't want that trash. It is the epitome of Chinese garbage. Nothing but fitment issues and the metal will rust like you drive down salted roads even if you live in FL. That price is a rip off. Also, what gaskets did you use on the headers?

Yonaka is the same crap, different seller. Avoid cheap exhaust parts. Literally, the only anomaly is the Megan Racing headers. They were cheap to buy while being basically AA headers. I'm pretty sure they stole the design making them actually good quality. Megan Racing is generally junk. Believe me, I'll say a dollar here and there but I traveled that eBay header road once. Never. Again.

What about the Megan mid pipe?

It also looks rather cheapish and is giving me "real man's cologne" vibes. But with stock US headers that are ultra clean, will I come out with a clean smelling Honda tone? Sec 2 and 3 will remain stock. Looks like I might actually lose midrange power from the lack of a proper crossover.

I may be the lucky one of this group, but when I dabbled on the catless side of life I never smelled it with the widows up. Ever. For whatever that's worth.

Flame suit on, but why do people put shite parts on this car? I don't spend other's money and I"m not judging, but damn--this is a legacy car, and there is minimum cost to play here, and to put junk on it just doesn't make sense.

Maybe they paid 5-6k for the car and it's a beater?
