Theres not a large noise increase in all honesty. yhowever the exhaust note did change alot. It became alot throatier and deeper than the stock noise.
My next car will only be getting a downpipe this time, and not the TBE as it did everything i wanted. gave the perfromane gains and made the car sound better without shouting chav. The full TBE sounded ace on track, but it was to much for day to day driving for me.
