Best order for Exhaust mods (NA)

[Ultramaroon]

Ace Laguna 90

Quieter than stock. Sounds like a real sports car with everything else stock.

From test track videos erfectly streetable even as a gross polluter. I plan on welding a bung in my stock front pipe. Hoping to legitimately maintain warm-engine cat efficiency.

Got a custom e-tune from Delicious and they seemed a little bit surprised that the catted header didn't make more power.

Swapping out the front pipe for a catted front pipe would definitely wake it up. It sounds really good driving through the city. (The stop and gos.) on the freeway it's not bad at all and there zero drone.
