I had my resonated tp for like 8k miles and they still smell like hell.. appearance is only half of it

 

How much did you gain?

It not just about power, having lower restriction and back pressure is better for turbo spool up and heat managment for the engine.

 

Its not the test pipes that smell, it is the exhaust gasses.

The above poster doesn't have a turbocharged car.

 

I dont have a turbocharged 350z at the moment which is no secret. I also currently have a stock exhaust on.

Some chose turbo first, blow motor then built motor, I went built motor then turbo.

Edited signature for you.
