If i use a custom 3"inch piping from the cat back to a 3'inch turbo N1 Muffler, then would the car actually lose more low end torque than the whole process is worth? Would it sound alot louder, but still deep. I dont have turbo and I just wanted to know if 3'inch piping from a Hi-flow cat to a 3' inch inlet tip of a turbo N1 exhaust would keep a great loud sound and not steal too much power from my car. So would it be worth it?

 

it will be loud and you might have a little power loss. its not worth running a 3in exhaust on a ka if its not turbo. stick with a 2.5 inch for sure

 

You might want to check your facts, there is a mod on FA that has proof otherwise...

 

True you wont lose power but you will have a LOUD exhaust. Please search next time JohnathonRuiz

enough about 3" on NA KA's. There's too many threads on that subject on this forum, not to mention other forums.
