Which Exhaust Is Better? Cat Delete vs High Flow Cat vs Stock Lotus Elise 2ZZ-GE Exhaust Sound Test

[@domtno]

The deep grunt at low rpm from catless sounds great, but, the top end on high flow sounds better!

[@Sals_Garage]

@@domtno thanks for the comment. Totally agree with ya 👍

[@carthingswithloren9674]

High flow sounds nice 👌

[@Sals_Garage]

Agreed, best of both worlds.

[@gregorylemmons5022]

Catless sounded best; most suited to the cars character (my opinion). Another great video, keep 'em coming!

[@Sals_Garage]

@@gregorylemmons5022 thank you! You’re very helpful

[@w1nnin]

High flow clean all through rpm range.

[@Sals_Garage]

@@w1nnin Yea, we chose high flow in the end. No regrets.

[@robertmoore119]

I bet they are nice for the whole range.

[@Sals_Garage]

@@robertmoore119 yes, sounds better and also better performance.

Great videos thank you

@@atomabc thanks for the comment 🙏

Excelente video hermano excelente elección, yo también prefiero el catalizador de alto flujo porque obtienes ambas cosas, buena respuesta en el arranque y buen sonido. Gracias por el video.

[@Sals_Garage]

Thanks for the comment!

[@east83music]

when u go catless, just weld in a resonator and u wont get the angry bee swarm at high rpm

[@Sals_Garage]

@@east83music thanks for the advice. I went with high flow cat because I didn’t like that sound at high rpm after letting off the throttle.

[@rotorblade9508]

the oem has a higher diameter, probably twice the surface area so you get much better flow for the same cell density. if the high flow flows better then it has a very low cell density and very likely 10x more emissions, though it might pass emissions except NOx. straight pipe is probably 100x higher emissions

[@Sals_Garage]

Thanks for sharing. Makes sense how you explain it

[@robertmoore119]

Greetings. Which is best? Stock is fine. But for my taste, if I were to choose, High flow. It is the least amount of work for what is likely desired. Catless is probably also good for some, but until you get a tune, your ECU won't like it. You will likely get a check a check engine light for CAT malfunction. It will think it's bad. But it's just not there. It could potentially affect the mixture in a negative way without a tune.

[@Sals_Garage]

@@robertmoore119 thanks for the feedback and advice. Good info 👍

[@chasew.l.5808]

catless is raw, but I'd say go with high flow since the smell is bad and the sound is still pretty decent in video :)

[@chasew.l.5808]

i mean smell is bad in catless

[@Sals_Garage]

Thanks for the feedback. We ended up choosing high flow cat.

[@2K8Si]

High flow for the win... 👍

[@Sals_Garage]

Thanks! That’s what we chose

[@TheBibleTruths7-h7r]

I heard the lotus has pretty much same motor as Toyota matrix the 2006 era model the zze

[@Sals_Garage]

@@TheBibleTruths7-h7r pretty much

[@TheBibleTruths7-h7r]

@@Sals_Garage WOW I have a blue 2006 matrix, I'll just tune it when I can. I been re doing stuff to it since it's a older car .

[@Sals_Garage]

@@TheBibleTruths7-h7r nice

[@shoryukensaucealtaccount7971]

👍

[@Sals_Garage]

@@shoryukensaucealtaccount7971 thanks bro!

[@DigitalDissident]

It need not even be said but please never go catless. Besides, it's loud enough as is on stock DP for such a tiny car. High flow is best.

[@Sals_Garage]

@@DigitalDissident agreed, too loud and raspy with lack of low end torque with Decat pipe.

[@waskus]

Only one would pass an mot😂

[@Sals_Garage]

@@waskus easy to swap them around in under 30 min 👍

[@waskus]

@@Sals_Garage yep, but people forget why the cat is there😉

[@Sals_Garage]

@@waskus luckily we have the high flow cat so no smell.
