I have been looking at all these different kinds of exhausts i have an 02 s4 which i have put an apr chip in. i was interested in the apr srt exhaust but im not looking to spend that much money. i found a vibrant exhaust which is much cheaper and i was wondering if anyong had any knowlege on whether or not that its a good idea to get that system. i was also wondering if i did get the vibrant exhaust would i be able to get that apr free upgrade or do i have to get the apr downpipes?? Besides the exhaust i was looking at and researching APR's DV and the bipipe. would those be a few things i should deffinatly look into? if anyone has any suggestions or any info or anything id love to hear it thnaks

 

For a catback, it more depends on the sound you want. Just youtube around and look for one that suits you. Vibrant is cheap... but it seems as though you get what you pay for. As far as the DV's and Bipipe are concerned, if you're only chipped just get a silicone TBB and some new DV's; even the 710s would be fine.

Back to the exhaust though, if you want a good deal on one (and this deal has been a secret of mine), check out this full titanium catback for around $800...

As far as the exhaust goes i'm still looking for one too but i'll check out that titanium one (thanks!). You could buy a new TBB but if you're eventually going to upgrade more stuff in the future then just go with the bipipe then you'll never have to worry bout the tbb again.
As far as the dvs are concerned, i have apr's as well and have had no problems with them or the bipipe.
Hope this helps

 

The bi pipe is over rated and If you want ill sell you mine. I am going to get the ARD pipes. check them out. A lot of GT turbo S4 run some sort of custom pipes to a samco TBB. As far a exhaust if your looking to make power spend your money on some DP. 034 makes some kick *** full 3" DP with a V-band connector. You could then buy a borla muffler for cheep and take your car to your local exhaust shop to finish it up. Total you might spend $1200 this way. Or your could spend $1200 on some other DP and another $800- $1200 on a shiny cat back system, now you just put a dent in your K04 fund

 

i spent 200 on my flowmaster cat back, custom build. ssac is super cheap and sounds good if you dont mind maybe grinding or welding or tweaking a little bit to fit.
