I think everbody here would like to know how much each exhaust system puts down on the dyno it would be nice to have all companies to actually show a dyno on exhaust so that we can actually choose the best turbo back or cat back exhaust system and not waste money on something that puts down low numbers.

such as:

hks
tanabe
b&b
buschar
ultimate racing
greddy ti cat back

There are a bunch of others i want to see numbers be for i fork over money.

 

yeah, but sometimes it is just personal preferance.

 

there is also (which you forgot):

Ams
RsR
RnR Racing
Turbo XS
Perrin
RMR
Espelir
Injen
Apex-i
JIC
Helix
GHL
Thermal

**EDIT**
5zigen
Borla
DC Sports
Fujitsubo
Monstor Sport
Ralliart
Stillway
Mines
Kakimoto
Ganador
Amuse
BuddyClub

 

DC Sports too.

 

All those as well i wish companies would actually give us some dynos if there exhaust are putting down good numbers i dont see why they would not want to advertise how much power they got.

 

any more exhausts out i missed

 

From what I've gathered, you can expect about 25whp regardless of the company. You have to remember that what they publish is the best they got in a single point. Where it comes in is more important than the amount of power. ie 23whp @ 3500rpm is better than 27whp @ 6800rpm. You wouldn't even feel/notice 5whp anyways.

 

fugitsubo

 

oooops...didn't see it before...sorry =)

 

Yep, one of the best for the money...the Megan Racing.

 

Maybe Turbo Magazine will do an exhaust shootout if we are lucky. I know the WRX exhaust shootout helped my cousin in his decision on exhaust.

 

as sated above, the gains on this car are all very consistent regardless of brand

I would not put stock in anything published in Turbo either
