ive got a 2.0l gl with above back section,what makes these things ssooo loud,is it just to do with girth or what?also while on the subject of gls/sports/n/a,what are the engine diferences against turbos?if turbos have roughly 240bhp against 125bhp,would this mean non turbo engines are almost bullit proof? thanks for your time.jus

 

i think it might be to do with the small baffle box it has it is small compared to standard....
