F-Sport Exhaust Lose HP?
Hey guys with F-Sport exhaust systems. It feels like after I put my exhaust on, my car got slower. I never did a dyno because I'm a broke azn dude, so I don't really know if I really did or not. It just seems like the acceleration has dropped drastically. Isn't installing this exhaust suppose to give you more hp or even keep it the same?
I'm wondering if it's just in my head, or maybe I did the install wrong.

Did you re-set the ecu?? My car feels more responsive. But it will take some more miles for the car to learn. Just keep flooring it when you can.
I don't think you could have installed it wrong.

I can pretty much guarantee that it's all in your head. The F-sport exhaust is only an axle-back which more or less amounts to nothing in terms of performance gains, at least on the ISX50.
I'm betting the main reason your car 'feels' slower is that your car is a lot louder but it's not any faster.

lol... thanks guys.. I'll try resetting the ECU tonight, hopefully that's the case, or maybe it is just in my head.. I just thought before on stockys I was able to accelerate faster.. now it seems like it has a bit of a lag in it. Anyways, I'm broke because I got all these mods done.... I should of just taken it slow, but i had to get em all! ALL!

any exhaust from the cats back is a placebo, you only get the mufflers for the sound your looking for, true gains would require headders/midpipes...
