Hello, have a question for you. A good friend of mine has a Mazda 3 with 165 hp in the Sportsline+ version. This is a sucker. Now he wants to install a complete system (exhaust) so that the sound sounds a bit more nurturing and sporty. My question is now only, can you hear anything at all with a sucker? The question is perhaps stupid, but can it be that the Mazda has very little power due to the missing turbo and thus does not give anything in terms of sound technology. You like to hack me if the question is stupid
