High Flow Cat vs Catless: What Should I Choose?

You also might want to consider insurance implications too; if you modify your exhaust and it leads to a claim, they might question if it’s street legal.

Good point. I once had to deal with that after an accident. They were very particular about my modifications!

I’m not a fan of the catless setup. It makes your car louder but can cause all kinds of issues with check engine lights and inspections.

So true! Plus, you might attract unwanted attention from law enforcement and emissions checks.

Honestly, thinking of going catless just for the performance gain seems risky given the potential penalties and hassle. High flow cats sound like the better compromise.

I’m currently torn between high flow cats and going catless. I’ve heard great things about both but need help with installation experiences. Any advice?

I had high flow cats installed last year. The install was pretty straightforward for my mechanic, but I did need to clear a few error codes after. Definitely worth the power gains!

Going catless? Be ready for some noise! I installed a catless system and love the sound, but it can be too loud for some. Just make sure your neighbors don’t mind!

Did you notice any drop in fuel efficiency with the high flow cats? I’m curious about overall performance.

I went catless and had some check engine light issues initially. Turned out I needed to get an O2 sensor spacer to trick the ECU. Maintenance-wise, just make sure to monitor your emissions!

That O2 spacer is a must! I had to install one too after I went catless. It fixed the issue but I’d still recommend going with high flow cats if you want to keep the setup more legal.

I liked how my car felt with high flow cats, but I noticed some drone on long drives. It’s a trade-off for the enhanced performance.

I would say high flow cats offer a great middle ground, especially if you’re worried about emissions and legality. Just keep up with maintenance!

Honestly, the decision comes down to personal preference. If you love sound and performance, catless is for you, but high flow cats offer better long-term benefits and fewer headaches.

What kind of headaches should one expect with each setup? I’m new to all this!

With high flow cats, you might deal with occasional rattle issues or have to occasionally replace them. Catless can lead to louder exhaust and potential fines if you’re caught!

Check this out: I installed my catless system with a few friends, and we might as well have been conducting a musical. Tools everywhere and laughter non-stop! Great bonding experience, too!
