Cat deletes or long tubes

[Scp-steve]

That's my question
I'm searching for a few more hp and I feel I don't need the whole 1k
Long tube header experience

I have a nice set of factory headers that are already
Coated in thermal coating so I feel right now I should at
Least try the mak cat deletes on my car first

The car is making roughly 660-665 hp at the wheel
And all I'm looking for is 700-725... I will add 3 psi
To my current 9 psi I'm seeing at the same time

Making 741whp with cat deletes and E85. Headers are expensive with install.

I'm going cat deletes

I'm debating doing the cat deletes. I have long tube headers sitting in the garage, but keep putting off installing them. Seems like it would be much easier to cut off the cat and weld that flange on than wrestling with the headers bolts.

Naw, you can turn them into a bolt in and unbolt solution too if you don't want to go with catless headers

Or gut the current cats?

Not gonna happen
I'd rather set the pass side cat up for an easy reinstall so I don't have issues with inspections
