Spec d exhaust
So I installed my spec d car back exhaust yesterday and
its sounds really high piched and I don't like that his do I
make it sound deeper like how I want it to sound
You can always try a different brand exhaust system, all brands have a different size and design of the muffler, which is what will change the pitch(make it deeper sounding)
A deep sound like that comes from a V-8 will never come out of a 4 cylinder engine.
