That’s great…solid gains. No check engine light or error codes?

No problems. We are gtg.

so what are you guys going with out there, magnaflow doesn't show any on their website since they made that custom one but corsa has them available..

I think my mufflers are MagnaFlow. The tight distance front to back is the constraint. Total out the door - parts + labor - under $1,000.

I do get a very rare CEL, maybe 3 times, in the past year. It is just related to the downstream sensors not "reporting back" what they are used to with the factory headers and cats. I just clear it with my code reader. It would be programmed out with a tune that Im not ready to do yet.
