Hey guys its about time I mod my Lexus IS350F and install some tasty mods, first thing first its the exhaust I am trying to acquire the ark grip exhaust for my car with burnt tips and I was wondering if they would hook up to the RR Racing Headers, then what are good tuning companies, right now im looking at,

M Force &
RR Racing
for tune.

Have K&N high flow intake, but let me know If I need aa better intake for these mods.

Also on top I want to get an (LSD) Limited Slip Differential how and where can I acquire one without spending 3k or even 2k, is the 2011 ISF LSD a direct bolt on to the 2014 IS350F?

 

Hi,

Yes the Ark Grip Catback will mate to the PPE Headers.

I would highly recommend the Cusco Differential: https://www.rr-racing.com/Cusco-RS-L...slsd985v15.htm

As far as the Intake, we have found the optimal set up to be the OEM Airbox paired with our Carbon Intake and K&N high flow drop-in filter. Most aftermarket Intakes the replace the OEM Airbox will lose power by drawing in hot air from the engine bay.

We have a proven, safe tuning solution for the IS350 that can be optimized for your set up: https://www.rr-racing.com/RR-Racing-...ig3xxtne02.htm

Please let us know if you have any other questions.

Thank you!

 

what are the gear ratios on these? Looking for more aggressive ratio than the stock 2021 is350 since it makes the car feel weak

 

I have PPE Headers + Ark Catback (make sure you opt to get it Catless) + RR Tune. Sounds amazing and tune is reliable. I am approaching almost 100k miles on the tune. Never any hiccups and still pulls strong to 7200.

For the LSD, are you planning on tracking the car?
