Ok, i've seen way to many post on this subject I want to know what you all think actually weigh the advantages and disadvantages not just say what you think is better. Personally I still have fart pipes and im not sure about the cats.

 

I choose Corksport because of its excellent design, looks, weight savings and cost. I honestly dont see any downside to it.

 

i have a dp/mp to N1 Duals.

pros, it sounds great, goes fast. boost builds up QUICK.
cons, can't pass smog, a bit too loud for other people (i.e. cops) to stand.

 

What do I use for a cat-back...

A 2.5in straight pipe, not muffler, works wonderfully.
Of course this is a purly subjective comment, I dont find it too loud, allthough others might.

 

I use the True Duals

I love them for their sound power and looks.
