Look into the APS turboback as well, I have been very impressed with the sound, quality and dyno numbers of this part, and you can even get it in a twin-tip which looks very stock... Sleepers are GOOD.

i would say RS-R turbo back, APS 3.5 turboback ( if you have a large turbo ) or the bpm twin dump system, but that is overpriced imo...

basically the least restrictive exhaust will perform the best, in other words something catless, without resonators, and minimal bends... with a sufficient inner diameter for your turbo

most 3" bellmouth / divorced wastegate downpipes with a 3" cat back will give you good performance gains. i've had good results with the stromung twin dump turboback, but it's kind of spendy.

The APS 3.5 inch must be the HOE/R5 or whatever its called, looks similar to the HKS Hiper... I love the quality of APS and would like to get that TB (with high flow cat), but... I'm planning on keeping the stock turbo... will that cause me any problems... also ill be running it on a Stage 2 AccessPORT flash. any help would be greatly appreciated as I've been searching for answers I cannot find.

I've been pretty happy wit my invidia turboback, only problem is that it is too loud (running catless). Has a perfect fit tho. Also, it got beautiful welds.

If you want just performance with nothing else...get a Bozz or JDM turbo back of some kind...a lot of them are completely straight through....my Trust DD catback doesnt even have a muffler, it has two resonators and I have two different kinds of silencers for it, its a dual tip...but they are both big...hehe.

I use tanabe racing medallion , fitment is perfert and the bends all stay the same diamenter not like some other brand. and looks awesome . tanabe is the one to go for if you want to see your friend trying to stuff oranges into your exhaust

for all out power the aps 3.5" dp is the best. now whether your car can put out enough hp to make the dp completely sucessful is another story.
