Has anyone run a dyno for HKS Hi Power Spec-L?
 

If so or got any info, would you please share it with us here?

I did some research and could not find anything.

:thanks::thanks::thanks::thanks::thanks::thanks::t hanks::thanks:
Thanks in advance!

Yeah I tried googling it, nothing. I wish they posted the numbers like greddy.

Figure 5-8 hp for a catback on these cars

Dyno'd.......results not that wonderful...

sad... thanks a lot tho!

are you still gonna post a dyno chart there? interested in more details haha

They may post it up later with their own write up....

When they first dyno'd the car with a K&N filter with stock exhaust it was 178HP. Today with the Hi-Power it was only 176HP....yes, a loss...but then when they first dyno'd the car it was about 2 months ago(its on the forum here some where...i ll try to find it)....so they put back the stock exhaust and dyno'd again it came out to only a 2 HP gain from the stock to HKS Hi-Power Spec-L. Changed filters from K%N, HKS Hybrid and OEM(little/no difference)

Lots of other exhaust companies seem to boast a 5-10 HP gain....but some I seen with dyno charts were done in 3rd or 4th gear....5th gear is where the 1:1 ratio is for the FRS/BRZ....

So in my opnion...without doing the entire exhaust system and or tuning there won't be a much of a huge gain in power...


But it does sound nice =] Hopefully a sound clip will be up as well.

here it is.....the first dyno....

Thanks man!
:):):)

The big gains come from removing the CAT's after the header. Most of the exhausts making over 10whp are header back. You are not going to see much gains from a cat back. The midpipe does not gain anything, and the muffler repalcements are only seeing around 2 whp.

I have the hi-power sitting in my garage waiting for my car :) don't want to hear about hp or dynos lol. Shhhh. Also have HKS air filter too :p

I just installed this exhaust and you'll be surprise how quiet it is. My point is that you can then buy the front crossover pipe with a high flow cat or cat less and see a better HP gain while having a good quality, low weight, not too loud exhaust. If it is still too quiet (or want more HP), then you can still go with headers:thumbup:

it sounds great....no worries, its a HKS....Hong Kong Special....JK!

welcome!

Where is the Dyno showing a HP loss for the HKS spec L? i followed links and it only showed installation. i have been hunting for this info for weeks
