Howdy. Just put a full 3" system on from turbo back and its too loud for me. need something track legal.

However, was thinking of putting my old STI center and back on and keeping the 3" decat. Rekong the 3" decat will change the ton/noise from the STI back box?

my guess would be, it might change it a little.

 

Which system are you running?

 

well im gonna be putting just a standard 2.5" normal STI system back on. but keep the 3" decat and use a reducer.

Just put on some (i believe) HKS full titanium jobbie. Really light but too loud for me.

 

Don't most people recommend the Revolution 3" system as being civilised ?

dunx

 

Have a word with GRD about the race system otherwise? Track legal etc.

I'm thinking of going full decat on my team ice system and with turbo change. Yowsa.
