I already had that set up on my blue Shelby, ARH 1-7/8 headers, OFR X pipe and the super snake axle back.
Headers and hi flow cats

If it wasn’t for the dam bar on the driver side swapping mufflers would be even easier. I then would consider some Cora’s for the cruises with my friends and then swap to factory mufflers for the rest of the time.
From everything I have heard about the corsa sports they sound amazing with long tubes.
I had them with just an off-road X and they were loud but nasty sounding! I just don’t want the car that loud all the time.
I love my Corsa and off road X pipe. Not to loud imo but the older I get the more I cant hear a dang thing.
Yes, Sports. Ive never heard the Extremes before,appears they are definitely louder,deeper than the Sports.
Do you have the Sports on your new car?
Sweet. I can live with this.
No I'm still running the stock mufflers. I'm thinking about doing the kooks axle back on this one.
Yeah they sound amazing in person.
I have the AR Headers with H-Pipe + Corsa Sports out back for about 3 years. Love the sound but lately on cold start there's a loud distinct rattle thru driver's side rear exhaust. I thought clamps then Corsa muffler but there's not much baffle inside a straight thru SS Corsa. No sound inside cockpit and it completely goes away within 2 minutes. I suspect the ARH Cats as that's where heat builds up instantly. I jacked it up for cold start but see nothing loose. it must be inside....Uugh!
My shop says ARH Cats have the most failures. He recommends Kooks but that sounds like quite expensive full pipe exchange! ARH is in my area. Since I'm in knee deep with ARH already I'm thinking of just grabbing two 2 new ARH Cats and just swapping them out. Not sure of the 2013 OBD allow for bypassing hogged out Cats to still pass emissions like earlier models. But I don't want the extra loudness & there's no HP to gain there anyway.
OP......Maybe some of the guys can give more feedback but if this is my issue ( 4/19 app't)
it might be worth considering when choosing headers with Hi-Flo Cats.

Every cat failure I've had was evidenced with a rattle. What I would do is get GESi catalytic converters welded in place of your existing cats. Vibrant Performance markets these. They're not cheap, but should last if you match the cat to your power level. That's what I will eventually do.
Kooks Green cats sound like they hold up, but these cars seem to blow out aftermarket cats easily.
I don't do anything like 1/2 mile or Texas mile runs. Too may back to back dyno pulls during various upgrades likely did mine in. But my modding days are over. AMR offered to give me a deal on a direct swap for new. They're in my area. I guess I can't complain about that.......price you pay to play. I imagine this can happen eventually with all "Headers & High Flow Cats".
Went to AMR spent $450+300 labor for new Cats that rattled like crazy when shaken. I was advised 20-30 dyno pulls often in back to back sessions will kill cats. New sound is absolutely amazing ....quieter at cruise....deeper everywhere...I could not be happier!
This time AMR clamped the Cats on both sides for 30 min swap with their straight pipe if I did more dyno pulls. But as we've all said before "I am done".
RE: Corsa's........I did mod the look of my Corsa Sports after install. I thought they hung low. Corsa explained their cans are larger & drop lower for their SS chambers to eliminate highway drone. I used masking tape around the rear body lip & shot both rear panels with 2 coats flat black header paint. Matching the rear air dam they seemed to disappear under the car. Here's an on ground then rear standing view.
A buddy also had the AMR system on his big power '08. During clutch swap Cats were found to also be rattling. In that case they hogged them out. Way cheaper since they were down. After clutch break in a follow up dyno to see if that effected tune showed no need for tweaking & no power gain w/o cats.
