New Exhaust for Mazdaspeed Proteges

Well...the Apex DP gave some where around 10whp. When I replace my Apex DP this exhaust, I noticed a pretty good increase again, so I would say close to 22whp although I don't think it is that high.

does this exhaust give 22hp at the crank? or at the wheels?
 
When I dynoed my car I only gained 9hp peak but I gained 30hp at 6500rpm. I don't know what it would have been at 7000rpm but the horsepower was still rising. BTW my speed is stock except for the exhaust. 161hp 167tq
 
Where are you going to get it from? I know JDM Sam has them for a pretty good price.
 
so this exhaust costs around 800 and adds 22hp at around 6700-7000rpm?? Anyone have dyno sheets or someone who has this exhaust, where did you get it from and how do you like it? Are there noticable gains??
 
The dyno runs are already posted on page 45 of this thread. If you want to get ahold of JDM Sam you can just PM him.(Thats his name on here) I think his site is autocrossover.com. I have bought a few things from him already and he will answer any questions you have.
 
I didn't see them on p45. Would you link to the exact post where we can see the dyno sheets? I saw a couple mentions of people seeing 22whp or 30whp increases, but didn't want to read 50+ pages to find the sheets.

Thanks.

Anybody using the silencer with this exhaust? I am still putting the silencer on because I thought it was too loud without it
 
how hard does the car pull with the addition of this and no other mods? i don't want to read through 50 threads but I might be interested in this but i wnat something that pulllls
 
The place that I noticed the big difference was at 5000 and above. The car doesn't feel like you should be shifting before redline it pulls all the way through. I don't have any other mods on the car right now and I had a SP2 which is what my baseline run was with.
