dyno results ppe headers on bone stock isf
I just went to the dyno last week to establish my baseline numbers on my bone stock ISF, the result where 340whp , and saturday went to the dyno again to see if my ppe header installation gained some numbers , the result was 370whp everything else bone stock, next week ill hit the dyno again to see if a drop in and joe z gain any whp. All test where performed on the same dyno, dynojet. Ill keep you posted ad let me know what you think

very nice numbers,
I just ordered my PPE and can't wait to install it.
How has the sound changed since installing the headers on the stock exhaust?

To help the OP answer the questions regarding the exhaust sound with just the PPE headers. It gives the car a more throater exhaust note that really gets the car noticed. At idle you can tell you have something under the hood, especially at cold start. Normal driving there is no drone, but at WOT it really wakes the car up and the beastly V8 comes alilve! Now the cars sounds like you got a V8 under the hood. Hope this helps and enjoy the headers guys!
Im waiting to see what the OP has in store for the exhaust. Im thinking of going Borla since its the easiest and cheapest to get to Guam.

Well i dont have any plans right now for the exhaust, i havent even checked because i dont want my f with any drone or loud noise i think next move will be custom mod of the y pipe on the oem exhaust and removal of secondary cats , who know maybe ill leave as it is !
Sound wise the car when you cold started sounds very diferent from stock, but when it reaches operating temperatures it idles down and is hardly noticeable, cruising in the street what you hear is the same oem hummmm but much louder but not to any point tht it bothers you or any body can tell you have something of course when you floor it its louder but ill say a 15% louder , for example my girl friend best friend and dad havent noticed any noise increase they dont even know i put them on . The noise in the cabin is hardly changed.
Performance wise you can feel it is a lot faster, i was impressed with my gains my goal is to reach 400 whp with the right parts i know im very far , next step is to see if really joe z intake and afe drop in put some numbers on the dyno, i dont mind if the joe z dont give numbers because ot looks good only reason i eont use it is if it lowers my numbers righ now an i hope it dont happen

Good numbers and way to use the dyno the right way! You're not going to hit that magic 400whp unless you change or modify the exhaust. Perhaps a removal of the secondary cats will help. Either way though, 370whp is a very good number and I'm sure the car feels nice an lively!

You number of 30 whp is bang on. I dynoed before and after my PPE header install on the same dyno, same conditions etc... My gain was 32 whp. So many people have talked about 50-60 whp gains from headers and its just BS. With the Joe-Z exhaust youll see about 16-19 wheel as well.
