Comparing catless Downpipes

[felcrum]

So I'll be installing the JB4+ EWG as soon as I hit 1200 miles. I'd like to order a catless downpipe. There are so many options in the market ranging from. $250-$450. Is any reason to choose one over another?

Twisted tuning has them for 350. I have one on my car and have 0 issues with it.

It just got shipped yesterday, and I'm at 700 miles already. So I hope to I'll be at 1200 when it arrives from Florida.

Cool! What setup are you running? Tune or JB4? CEL?

aFe is poorly designed/produced. I'd suggest staying away from them if they're even selling them anymore.

Subbed for info. IMO piping is piping as long as it's true stainless with decent welds they should all preform similarly.

This is the right answer. Fitment is important too, but generally.. Pipes are pipes.

Jb4 cannot clear the cel you will get, I assume you don't care. Why not just go with an AA catless?

I have the JB4 with a catless Titan dp.
I’m running a MHD bef with the JB4 for better overall performance and to not get a cel or even a shadow code.

I would suggest Titan as I had others in mind a few months back and went Ritu Titan because honestly, it’s just a pipe and paying over $300 for a catless pipe is just a waste and will provide no added benefit.
The Titan was easy to install, no figment issues.

Eventuri intake with twisted tuning catless downpipe and twisted tuning ecutek 91 octane tune.

has anyone heard of any problems with throwing a catless on an untuned supra?

The issue is you will get a check engine light due to a missing cat. The dealer can void your warranty if they are ducks and see this.

Check out the MAD downpipe, it was our most popular option when we used to offer catless DP.
it also comes with a lifetime warranty

Piping is piping however there are subtle difference that are important to me and I feel like not all catless pipes are made the same. There is comparision video by speed industry that goes over some key difference but alas only catted. I inlet size are not all 4.5inch and some at under 4inches at the bell mouth and the piping can restrict quickly. To me as far as cattless goes
1. ETS
2.Powerneedy
4. AA ( i dont think they are making them anymore)
3. Titan and all other alt DPs
