    • Overall nice, don’t forget a gasket and bolts.

Very nice build quality. Went together very nicely. No fitment issues, no trouble with factory hitch. Has a nice rumble on start up. Very mellow idle tone, but it’s a bit too loud during light acceleration. You hear it in the cabin unless you’re at 0% throttle which I’d prefer you didn’t for putting through town at low speed. You will hear it constantly at highway speeds, no drone or irritating tones. You definitely need to buy a factory gasket and a new set of bolts for the catalytic converter connection. ... show more

    • Improves more than just the sound!
I paired this with a high performance air filter and I can 100% feel the difference in my throttle response. The GX stock feels like it can’t breathe. This combo creates a much more linear power curve and no delay in throttle response. Sounds great. A little loud at times, but it’s a performance exhaust so that is expected. There was a rattling noise when I first installed it. We tightened the clamps after about 2 weeks (500 miles) and I haven’t heard the noise since. ... show more

Factory tip fell off years ago, fine just replace it. After muffler piping though, gotta replace it now. Easy to install, plus added hidden effect and lil aggressiveness in the sound. Worth the purchase

    • Defective weld
Some of the hanger welds were defective and had to be re-welded. Also exit pipe did not come out at factory location like the other aftermarket pipes did.

    • Awesome exhaust
I love the exhaust but have to give it 4/5 stars. The packaging was great but the exhaust exit was slightly bent. I already was installing it when I noticed so I didn’t bother getting a new one. Other than that, great sounding exhaust.

    • Love love love the growl
Installation was a breeze. Make sure you lube up the exhaust hangers to remove old and install new pipes. Fyi you may have to do a little custom bending on the last tailpipe piece to clear the axle and not rub the frame.

    • Just Right….
Went on a 2019 Lexus GX 460, and is perfect. At cruising speeds there is no difference, but acceleration sounds nice and solid without being obnoxious. I’ve done a number of exhaust upgrades to vehicles in the past (Jeep, Tundra, Lexus SC), and feel this one came out the best.
