Akrapovic Slip-on vs GT4

PINHEAD · 04-18-2013, 05:27 AM

Made a quick video to compare the 2 exhausts on my car with similar conditions. Akra GT4 is freakin loud....

Yep, sounds like a track car.

damn that's loud, but that's how all straight pipes sound really.

positiveions · 04-18-2013, 02:29 PM

rjd598 · 04-18-2013, 02:32 PM

Alen E90 · 04-18-2013, 05:25 PM

PINHEAD · 04-19-2013, 08:40 AM

really loud and Im actually embarrassed about it.
shakes the whole garage and if im in a parking structure it sets off alarms

GOLFFRR · 04-19-2013, 10:15 AM

dang it that wont work for me then. my neighbors would kill me when I fired that up every morning at 4am on my way to work lol. My Akra EVO is already shaking the garage.

cold start is not much louder but WOT and also downshifting its much louder. Cruising is not really any different than evo unless you lug the engine.
the drone is still very minimal

everything is just alot more sharp and more of a bark than a growl, with alot of backfire

GOLFFRR · 04-20-2013, 12:18 PM

^^so the cold start is almost the same as the Evo? if thats the case I may be able to run this set up without the neighbors knowing the difference

its a bit louder, but the biggest difference is under WOT and downshifts.

GOLFFRR · 04-20-2013, 12:46 PM
