cant make up my mind on these 3...

i have true dual borla exhaust

anyone have experience with these and an tell me or give me insight on which route to go

 

This issue has never been covered once on this site. Hope you find your answer.

 

^ yup everyone seems to have their own opinions between these 3. I'm pretty sure there's another discussion about this with a lot of people's opinions. look it up!

 

I do not have experience with any of these, but I can give you my opinion on all of them as I have done a fair amount of research.

Berks are the most popular but some people complain about them failing prematurely. Some also complain about rasp.

FI HFCs are a better choice than the berks, in my opinion. Haven't heard really any bad things about them.

ART pipes are going to be the best option as far as performance, sound and build quality go. They will be quieter in all the right ways (less drone, rasp, volume). However they will smell since they are not catalytic converters.

 

Do I need to buy the optional 02 bungs?? Or not necessary???

 

Do you have Uprev? You will throw a code if you don't have o2 bungs.

 

Uprev as in the tune?? If so no I don't but plan on getting the tune so would I need a 02 bung for each pipe or just one?

 

No, in fact they won't fit. Fast Intentions already comes with everything you need to install and go...Gary

 

I hope I went with a great choice !!
Chose then over berks and crawfordz
