Catless downpipe with 4” exit recommendation

[ntfrendlyGR]

Just as the topic says. Looking for a catless downpipe with 4” exit recommendation if any even existPrefer not using an adapter as I have a RK 4” exhaust Currently have ETS catted with 4”. Thought about just punching it out but I know from experience aftermarket cats don’t just break out with an air chisel and drill like OEM ones. I bookmarked several when I pitched my Catted one but it seems companies got away from 3.5-4” exit.

Most companies I contacted are 3.15. There is a 3.5 on one fast Supra. Oh well just gutted the ETS to keep the 4”.

DAW made their 5" catt-less with a true 4" exit for me. I had the ETS and switched to the DAW. I had to call them to make the exit 4". Didn't charge me extra at the time.

ETS offers a 4" outlet. I would contact them to see if they will make you one without a cat.

A yr ago they offered catless, but recently when I contacted them, they said they only sell catted ones now. Which I have
