i saw stainless steel 3 inch straight midpipe without high flow cat or those thing that kill the sound which would be better performance wise? and how prone are u being pulled by cop with the smell and loud noise with straight pipe

 

Get a resonated midpipe or a high flow cat... I had a straight midpipe and it was unbearable.. I ended up building a resonated midpipe..

 

how was it unberable and how much HP do u lose by getting resonated or HF instead of straight mp

 

if you are running non-sequential or single turbo with a midpipe and catback its pretty fricking loud. With a resonated mid or hf cat you might loose 2-3hp maybe.. but its worth not being harrassed by the cops and being able to hold a conversation in your car going down the road at highway speeds.
