Muffler delete catback(tune?)

[5ohh_kenny]

Would a tune be necessary when running the 3" hooker blackheart muffler delete catback? I had it in my car for about a year without really thinking about this. I was under the impression the cats were the restricting factor here and I figured if more widely used exhausts like mangaflow competition catback don't require a tune the marginal flow improvement from straight tubing wouldn't warrant a tune.

Drove the car for about 10k miles with the hooker catback before taking it off for noise reasons. Now I've got to thinking about it and worrying myself I drove it for so long when it may have required a tune.
Probabaly just the typical over concerned mustang owner but I figured it was worth asking.

Thanks

You've had it on your car for a year already, pretty safe to say a tune is not necessary.

No tuning necessary for any exhaust after the cats.
