Plus I only just passed EPA sound test with my 2" so I'm keeping it as is..

No0o0o0o0 i have a 2''
did it cos i like cars quite as hell but...

worse mistake ever

its so restrictive that my exhaust acts as a boost controller ..
too much back pressure
max boost i can run with the 2'' is a tad under 7 psi

Maybe that's why my spring can't hold 9 psi?

I'm installing a turbo smart bleed valve this weekend and we will see lol

pretty interesting to know

cos i have a t piece thats unblocked
which is ment to be blocked but so far no boost spikes and stuff

and my tuner and fabricator said it wont run anymore then 7psi cos of back pressure SAD!!

i told you a long time ago dude to get the 2 1/2"
let me knowif you want a recommendation on a place.

Performance Exhaust did most of my conversion and exhaust system and its a beauty

Yes i can vouch for performance exhaust. They did our 2.5inch exhaust for a decent price. Happy with the quality.

Mandrel or press bent?

Update

My car dose have VTec its just not accessible through e-manage lol

Still working fine via the standard ECU

As I assumed coze there's no way my car should make 116kw at 6 psi without the help of VTec?

Just used this little trick

you have to get mandrel, press is just crap
maybe a new ECU would be good also
cos with my car you can see a jump when vtec kicks in.
vtec + boost lots of fun!

Na e-manage works just fine with my setup...

Yeah I'll be going mandrel if I can afford it lol

VTec on DOHC has far more impact than on the SOHC motors
