Is this a good thing for the rx8 or bad? can someone tell me if i should or shouldnt do this. does it sound a lot louder and better? do you gain or loose horsepower? Thanks

 

I cut mine out since my Greddy exhaust still didnt have much sound to it.

It def picked up some noise and to my surprise seemed to have alittle more power.

More noticable power change than when I added my Greddy cat-back.

 

tends to make the exhaust sound raspy - like a chainsaw . Would not advise it myself .

 

Ya, makes it sound like a ..... rotary.

 

Cutting out a straight flow through resonator will do nothing for HP gains. But it will make the exhaust a little louder.

 

Did u just cut it out or straight pipe it as well?

 

Get a straight pipe if you really want it loud or a high flow cat.
