IMHO: No need to be catless to be loud: Cargraphics "Loud" (in my car for 6 years now) is more than loud enough. Turns head and get thumbs up every time I rev'ed, especially in an enclosed garage .

Very muscular sounding and screams like a mother :-) at high rev. GMG exhaust is another loud one, with cat.

 

We make each one per order, cats, no cats, oem tips vs dual 3"- straight cut or rolled... custom per your wishes. I even make the mufflers from scratch with various options for flow and sound...

Thanks! And Yes the straight pipe is the key, no larger turbos by the way.
