Hi how are you? I coulnīt wait and I just bought the STI 2011 Sedan.
Do you recomend the new SPT exhaust system?
How many extra horsepower do you get?

I donīt want to loose the waranty, I really like the sound of the SPT ( not to loud), is there another aftermarket exhaust system with more horesepower and same sound as the SPT?

Thank you for your help

The SPT is a good exhaust. I really like the HKS and the Greddy systems. If you get a CARB approved exhaust it dose not void any warranty. Allmost any good exhaust system will give you around the same HP gains with a factory tunes car. Once you add more bolt-ons and retune you will see greater results with a good exhaust. We almost allways us the hks and greaddy systems. I think there great.

Just fyi i heard that if you get any new mod for the 2011 sti, you have to get it tuned after you add on the mod or your ecu wont work right and your check engine light comes on
