im looking at downpipes for my sti. which ones would you guys reccomend? how hard is it to install it? and what else do i need besides the downpipe?

 

Downpipe installs are pretty simple and straightforward. Please take a look at our Vishnu tuboback- it's 3" throughout, has a high-flow cat, and is a twin-tube wastegate discharge flange design. The STi turboback by itself shows about a 20-25 wheel horsepower gain on the dyno.

 

Whatever pipe you go with make shure that it either has a wastegate pipe or is a big mouth to suck more exhaust out of the turbo. The stock one and HKS have a flat pice of steel there and make the exhaust get pushed over the "barrier" to the pipe.

Is the STi TBE you mention the same that is on the Stage 1 kit you guys are currently developing or is that a different TBE?
