Intrest in a sedan center exhaust rear section?

You cant go off the stock axle-back weight. It weighs almost nothing since its all 18g material. Toyota definetly knew how to produce an effecient exhaust in terms of flow and weight. The entire stock exhaust weighs about 27lbs. My exhaust weighs about 10lbs more...due to 16g construction and extra resonators. The stock muffler is open inside with one baffle and a spring loaded valve. Packed mufflers/resonators weigh more.

In the long run however 16g can take a beating compared to 18g...if you look at it wrong it gets dented haha

Btw ive seen several exhausts like that one too and ive considered it
