Best catless downipe exhaust setup

[JP Strunc]

Hey, just installed ppe catless downpipes and it rasps really bad in that 3-4k rpm range. Current exhaust setup is the downipes to a third cat delete with an x pipe to stock resonator to muffler delete. I was thinking flow master fx mufflers. Any thoughts?

That is the set up from my old SHO.

3rd cat deleted, Magnaflow Resonator, into stock mufflers.

If I was in your shoes, I would remove the x, add a magnaflow resonator, and add magnaflow mufflers. You do not want to put a baffled muffler on a force inducted car, but the FX as you mentioned aren't baffled.

This might be an easy avenue of approach as well.

Do you have any old sound clips with that setup? I also have stock mufflers I could throw back on, but not trying to buy a whole exhaust system.

I do have my stock mufflers I could throw back on, but not trying to buy a whole exhaust system. I’ll have to look at your sound clips
