wich gives most power and at the same time keep a low sound level?

Piggie pipes vs. Miltek Cat back.


And will fit my system/goals best?
I have a tiptronic s4 apr chip + k&n so far...but are planing to upgrade to k04 in the future.


Thanks

 

You're comparing down pipes and a cat back setup. The down pipes are definitely going to give you more gains.

Piggies won't really increase the sound of your exhaust, it will make the turbos more vocal though. The Miltek is prob one of my favorite exhausts because it's really not loud and maintains that "sleeper" image that comes with the S4. Surprises people when you smoke em.

Since you're chipped, the next best power gain you'll get is gutting your pre-cats (piggies), I would do that next. But, if you have money to spend, do both. Piggies are basically free, so do them and spend your cash on the Miltek. That will be a nice Stage 2+ setup.

 

piggies will give you a good power increase and the sound will be a little louder if you keep stock catback. if you just do a catback like a twin 2, it's not too loud and you'll get decent power gains. dp's will give you more tho.

 

Thanks sweeds4 & meatbiscuit!!

 

yeah, if you want to hear what mine sound like go to tinypic.com and look up xs-power and you will see my vid, you can rally hear the ko4's when i rev it. I have the ssa full exhaust right now, but loved my borla and pigges deeper sound more
