downside?you neighbor will hate you & you friend might feeling embarrass while sitting in your car,everybody will stare at u wondering why is car sounds fast but in fact it's crawling on the street.
anyway,ppl are looking for performance by modding their exhaust.what are you looking for?attention?
hahah relax man, thats why i asked if theres a downside. I know that when you mod you intake and output system the cars power increase. So i wanted to know if i put a big muffler would the power output be different than putting 3 pipes? Please dont flame me, im a newbie in car community :)
btw i think my cars performance is quite bangin' ;). Not that fast but deffinately not crawling on the street man :).

. My friend/neighbours car is a saga with no mod except sports exhaust. its FREAKING LOUD but my community dont really care. hahah, Theres lambo,ferrari and an aston martin behind my house so i dont think my car would be a problem to neighbours :proud::proud::proud:

High pitched sound you need a open pipe or straight pipe,short can & most important of all is the engine ability to rev to extend level of permitted rev.
The car normally rev around 7k-8k & that is why the 4 banger on car cant have the F1 sound like 4 banger on most big bike which is normally rev around 19k(250cc I4), 16.5K(600cc I4) & 13.5-to almost 15k(1000cc I4)
But straight pipe can produce loud sound without any good rythm & high pitched dB if the engine cant sustain high rev capability.
Hey man thanks for the detailed info, this will help alot
