Need help. Went catless and i regret it

[1slow.s650]

Hello! This is my first post in this group and I’m looking for help for the next steps.
I have a s650 that currently has a whipple from VMP with a 3.625 pulley and a BAP running a e30 blend. I recently gutted the cats and I’m currently regretting it… I’ve been looking everywhere for cats that reduce smell and won’t blow out. Any help here is appreciated thank you!

You're in California with gutted cats..... Are you getting any DTC codes ?

I got that taken care of and no CEL light. While none of that is an issue and car seems happier this way I hate the smell.

Well I know what @engineermike would tell you. Start searching for take off GT500 or Hellcat OEM cats. Find a good Fab guy and welder and retro fit the cats.

Go straight E85 and the smell will no longer be an issue.

Was wondering this.

I wanna go down this route but was wondering how well they’d handle with E and I’m pushing a little over 800whp. I’m afraid for them to blow out

There’s no tuning available for them at the moment. e30 is all we can currently run

Deal with it until tuning is available or go motec. I say that thinking Motec will run a gen 4 coyote

I'm out of my wheelhouse on that. I can say I know a guy with a 900 HP tuned Hellcat and knock on wood, no issues in the past few years.

 

[K4fxd]

Yes, best bet is to use GT500 or hellcat or Ferrari cats, they should hold up

 

[K4fxd]

Just a fyi, `100ll won't stink like pump gas. I think the EPA requires something like what they put in natural gas to make it stink without cats.

EDIT

In Ca they have 100 octane unleaded av gas that might not stink in your car.

sorry for going off topic but how can you run a supercharger without being able to tune for it?

 

[K4fxd]

When I was a kid exhaust from cars did not smell bad

 

[K4fxd]

The EPA or CARB did not exist at that time

True story !
Reformulated gas is nasty.
