Default 200 cells catted headers and single pipe side mufflers delete into OEM center muffler

This is a 200 cells catted headers with not valved side delete, single pipe into the stock center not silenced path (the path used when valves are opened)
just a quick test revving 0 4k rpms
inside cabin recording and both windows open (you can hear the belt alarm at idle)

differently than the single pipe with the stock catted headers (droning at 2.8k rpm as known) , the 200 cells catted headers surprisingly shows no drones or booming,
sound is loud but flat6 glorious

so far so good,
i will retest it cruising and test wot and a pair of launch as soon i have the time to reinstall the rear bumper

I could stand it possibly a touch louder so Iíll just unhook the valves...plug the line the a golf tee and zip tie and see how that goes.

Those big heavy 45 lbs of side mufflers donít do a whole lot they do some in making the exhaust too quiet...glad those are dumped off the car
Do you have stock headers?
