Ugh I hear that same exact timing chain pinion gear whine on yours that I've had on mine (2015 GS 350 F-Sport AWD) for the past 4 years. It's the most annoying noise to me and my Lexus dealership even replaced it once under my extended warranty. It started around 50K miles and now I'm at 99K and I can't help but wonder if eventually it will fail. I told the dealer that I'll be back some day if it does fail and I'm going to fight them over it. They said "Well it's documented and hopefully you won't need to". By the way, bummer you didn't do a "before" sound check of the OG exhaust. I love my F Sport but have always thought the exhaust is boomy through the rear seat and trunk area at constant highway speeds between 60 and 80. I'm in my late 50s and I'm over the boy racer era of my earlier years when I played with custom exhaust tuning. 😜
Oh is that what it is? Lol yeah it is annoying, I'll have to do some research on it. I did do a small stock vs axle back comparison, but yeah you're right I should've done a longer one.
@@billychen7920 yep used oem hardware, nope it's not welded on. I installed 2 diff axle backs (invidia & tanabe) on two different 4gs, and none of the bolts were welded.
@@ph0bolus Oh thanks for answering, just another question to ask. In your opinion which is easier, removing the bolts or the nuts? About to tackle removing the axleback and your guidance would be very helpful.
@@trivinpham6024 got lucky, got it locally for a steal on fb marketplace. Still haven't put it on yet though. Got my eye on another car, so this one might have to go.
the rev limiter sound for these cars are unbelievable with this exhaust, glad it all went pretty smoothly.
Thanks! I feared the worst after the shop had issues installing the lowering springs, thankfully the exhaust wasn't too bad.
Please keep the great content coming
thanks will try!

@@ph0bolus Oh cool I'll go look for that.
Same here bro!
Yess sir 😂😂 damn the invidia is so quiet!! Is it as quiet as it is in the vid? Excited to hear the mid pipe tho!!! Great vid man as always.
@@EddieGS350 yeah, it's pretty quiet. Don't really hear anything until 3-4k rpms.
Hey! Wanted to ask, did you reuse the OEM hardware? If so, how'd you manage to take off the nut off the OEM axle back? Heard it was welded on.

@billychen7920 bolt is probably easier, just spray a bunch of penetrating oil on it and let it sit. Mine wasn't too bad thankfully.
How did you get ahold of a invidia mid pipe heard they've been discountined on the gs
@@cartercheney3154 picked it locally off fb marketplace

How much did you buy the wheels for? Having a hard time finding a used set.
@@jnjrq50711480 CAD for the wheels alone, they came with tires which I sold for 420.
Did you get rid off the F ?
@@qnunyuh8417 nah still got it, it's been at the lexus shop for 2 weeks. They're trying to figure out wtf going on with it lol.
