Hey guys I'm having a hard time finding out if some of these aftermarket mid pipes would fit on a 460? Would the Invidia mid pipe bolt up? As far as axle back exhaust in concerned would the top speed exhaust work even though I plan on having an exhaust shop modify it to fit? Tanabe is definitely a good option but I'm not sure I want to dish out 800 just yet. Thanks for replies.

A member named Designo has that same mid pipe on a gs460, but i if im not mistaken he lost power from it.

Fausty

Thanks I hope he can chime in. If he lost power it's probably due to a loss of back pressure.

im pretty sure Invidia / Megan mid-pipe is bolt-on. U probably have to modify the heat-shield. Or just take it out.

expect mpg to be drop, just FYI.

Never said I lost power!

I think you're confusing the issue of my GS460 having 322hp as opposed to the US version having 342hp.

Here's the video of my setup.

Thanks for the post. Good to read you didn't loose any power. Your exhaust sounds really nice!

Pics showing Mods needed to get the mid pipe to fit the 460 flanges and O2 bungs.

And a video of what an un-tuned 460 with a TRD supercharger from a Toyota Tundra will do.

Nice sounding exhaust

Designo how did you get that trd supercharger to work? Untuned you risk hurting the motor right?

I second this question. I have been looking for performance upgrades for my GS460 and everyone tells me "Not Possible"! There is no chance of getting into the ECU for re-tuning

That's correct gentlemen, that video is the only video you're ever gonna see of a GS460 running a supercharger because it's not only impossible to maintain, but out right suicidal to your engine!

I used an Apexi Neo AFR device to get the ECU to keep timing in check but that bloody device on the Lexus is just too damn stubborn and smart!

Was pulling timing every run after that and finally made my AFR go from rich as Trump to as lean as Coleman! Almosr blew my damn motro apart!

Hence why 2 hours after this video was shot, we removed everything off the car!

By the way, the 1UR-FE block has an awesome compression ratio! I just don't get why they made her so difficult to crack. Force inducing her would be ideal! You'd probably pump out great numbers from her!

Fausty

That is crazy. I don't get why they make it so difficult. Or at least wait a few years later to unlock the ecu. I want to mod my car damnit.

take your car to zayani performance and have him instal an AEM stand alone or a link ECU

How is there a guy with a is f running a 100 shot? Untuned maybe?
