I’ve been thinking about toning down the rear but adding this has stopped the squirreliness I’ve been feeling above 60-70 mph. Sort of that looseness that doesn’t feel right VS. the looseness you want. I know some people want the tail end real loose but i feel like at lower speeds the diffuser hasn’t altered the car and at higher speeds it helps plant it more - I personally like the car to start with the rides on rails feel because I can tell when it’s beginning to hit the edge of traction - not just on/off... and panic. I need to do an alignment on my rears and maybe adjust my coils again but it’s acceptable, not optimal. right now.What differences are you feeling?
it added a higher pitches whistling noise and some extra rattles. I think it’s when the exhaust and diffuser bounce - I also left a nut that slid wayyyyy down and stopped against one of the exhaust curves. it was stainless aka not magnetic so I couldn’t get it out. Hopefully that bounces out eventually or I’ll drop the whole thing when I retorque everything.does the change your exhaust sound in the cabin at all? i imagine it might.
for posterity if anyone is interested. for 5th gen 4runners - an easy, cost effective sound upgrade, without amp or headunit so far (because I haven't made up my mind):Focal speakers
