L99 headers with stock exhaust

As the title says I'm new to the forums but I've always read on them for advise but I have a question has anyone ran arh,kooks, or stainless works headers with stock l99 h pipe and exhaust? I keep debating to go with full exhaust for cheap or slowly build the exhaust with top name parts!

I went with the ls3 exhaust. My tuner had a couple take offs so he swapped the big l99 for the ls3 and it worked perfect. Love the sound and of course no drone. I have kooks and hi flows.

Yep, Plenty of people will run headers with the stock exhaust. There is not much benefit of changing out the exhaust, so invest in a set of headers and if you can, try to get your hands on a LS3 system without the giant resonator.

Best regards,

No, just a stock take-off catback exhaust. The LS3 catback has an actual H pipe and bullet resonators rather than that giant thing they call a resonator on the L99 system.

Best regards,

Tyler

I ran Kooks long tubes + their cats and the remaining stock L99 exhaust.

Not much louder at idle, but noticeable in upper RPMs and definitely noticeable at WOT.

With the stock exhaust there will be no drone. Drone comes from the mufflers, not the headers and cats.

Here is my car with ARH headers, cats, tune and Corsa cat back:

All of them sound great but it's still hard to deside! Might as well put all the names in a hat and draw!!

The mid section of the exhaust is different between the LS3 & L99, the LS3 exhaust is pretty much straight through between the cats & mufflers. The L99 has the "box" resonators to cut the noise when AFM Kicks in and off.
