T the amount of data you possess never ceases to amaze. When you get the car out for a drive i have to get your opinion on it.Different.
GT350 has a 2.5" diameter inlet and a 2.75" outlet.

Lethal's delete pipe(s) has to match each. Note, the GT500 and the GT350 use the exact same resonators. The "X" sections are unique to each however.
The OEM exhaust is great. I was personally after some of that GT350 snap crackle and pop. This gets closer. Tob’s video highlights it best from insideLooks and sounds great. Honestly, if I had a factory GT-500 exhaust I'd be happy. It sounds very nice IMO. The Lethal resonator delete sounds a bit more raspy in Sport mode. How does each sound from the driver's seat.
I think you pick up a few ponies for sure. Lethal performance has a video on it that Tob posted above.Any performance gain with this?
