Also, how was fitment? I believe the Apexi has wider pipes versus the Borla Axle back

It'll crackle sometimes, nothing mind-blowing but it's there. Pop, not so much. There's a vid by K-12 star
at around the 1 min mark it's very very similar to what it sounds like.

As fast as fitment goes, i didn't have any issues.

Yeah, I do...i had the full invidia Q300 set up on my previous Lex and while it did sound... "smooth" it was too quiet for me. I wanted to add headers to this one, but that was too much... even for me.

Quad exhaust - how much do you want to spend?


I don't think Aimgain actually sold any of these active exhausts. I was unable to find them on their website. It's too raspy for me even in quiet mode. I prefer a smoother tone from my V6s (unless it's an Alfa Busso V6, then all bets are off).

If you want to get the loop muffler version (same tips, different muffler, lovely tone, if I had the money I would have one) the cost is over $5,000.00 with the diffuser and paint.

Sounds good!
I don't want to spend much, that's why I didn't go the Apexi route.
But, depending if I can get a deal on the Aimgain or Lexon diffuser, I can purchase some burnt quad tips and weld them on...

I did not know that anyone made the Loop for the 4th Gen GS. Loops Flow very well. Great Tone. Yes the one in the vid is Raspy and sound again like a bike engine.

I am currently running a Tanabe system. I have this Loop from the Top Speed Rev 9 maker of lots of the exhaust that the MB guys like. Its loop that flows like crazy but is deep and quite. Its was made for the Lexus RC, but they don't make anymore because they said everyone said it was not loud enough. Not loud, flows very well, that's for me!! I plan to graft it on soon! Loops are nice! Good to see you know about the Loop system secrets too! Loops Rock!

Aimgain, but you pay for the privilege.

https://www.topendmotorsports.com/le...ystem-1555.php $2,625.00
https://www.topendmotorsports.com/le...less-12868.php $3,325.00

Spendy for an axleback, and I don't know what the difference is between the regular and the BS Class, but those are both for the standard bumper. These loop over to an unfinished tip; the quad tip version loops under to meet their diffuser. But if you want the quad tip version with gorgeous carbon/stainless tips, it's $4,200.00.

I imagine they use the same mufflers across all of their loop systems -



The 3IS C is a little raspier; I wonder if it also has a midpipe.

I love that Crown sound. I'll pass on the other 2 though. Do you know if that Crown is the 2GR with Super Charger in the Vid?

GRS210 has the 4GR - 2.5L V6. I believe they sound the same as 2GRs though.
