need help on testpipe/custom exhaust

**romell** · 05-04-2008 06:43 PM

hey guys had a quick question. i was going to do a testpipe/custom exhuast.. now here are my options

2.5" testpipe and a 2.5" custom exhuast... or what i REALLY want to do is full 3" custom exhuast from turbo back... please do keep in mind.. i do have a ko3... and am not going to upgrade it.. if i do maybe a k04 or a gtrs thats about it. so basically lets talk from a k03 standpoint... 2.5 or 3" all the way turbo back... cause i heard that 3 inch isnt good cause u need some backpressure... some say fuck it.. its fine nothing wrong and plus it sounds like a monster with a 3inch.. so just needed some help and it would be great if i can get some feedback thanks!

2.25 or 2.5" TP/DP and 2.5 splits out the back is more than sufficient for K03/K04

Hell on a k03, 2.5 to dual 2.25 just to save $ on the piping.

really? damn. cause the price is going to be the same no matter what u know.. hmm.. and loudness wise? really i dont want it to be like some shitty loud kinda thing.. but i do want it loud.. before i had a AWE exhuast (with no downpipe and no testpipe) and my think was decently loud. wasnt that bad.. it was like a little louder than a z i guess.. but i really want something.. then when im on the highway and i shift fownto 3rd or 4th i want that exhuast to realllllly open up.

Dual 2.5" will be louder then 2.25".
