Opinion. Most restrictive component in stock 6.2 exhaust system?

[Ex Euro Driver]

Short of having a custom exhaust fabricated, what component of the 6.2 exhaust system that if replaced will yield the best increase in flow/scavenging?

Exhaust manifolds. Go with long-tube headers.

american racing headers. also the stock exhaust the 3rd cat i cut off and used the 3.5 magnaflow and that flows well. mine made 409 rwhp with intake/tune/3rd cat cut off and the magnaflow muffler

ive done about 25 installs sold many more online and the new owner of my old 6.2 escalade i did them on also recently with the magnaflow muffler. its not really that loud. the catted ones do clean up the air (no cats will smell it at a light)

1 7/8 with catted y pipe american racing headers/magnaflow 3.5 muffler replacing stock/stock rear reasonator in will be fine. if you need pricing on the headers just PM me
