hello mate

hey welcome fellow GSF owner

well its a 15 year old car now so might as well learn to live with it or just replace it with a 2nd hand part

your not gonna get much real info from members here with IS with towbars 

hardly any one has put em on even on the older models

best to consult your local lexus dealer

The mid pipe off the ISF is better than Nvidia etc simply because of the size. Dual 60mm into 90mm resonator then exit size is 70mm. The 350 in comparison dual 50mm into 60mm in and out the resonator. The rear pipes after the factory T piece are tiny at 40mm or so each. Mine are now 2.5 inch each from the T-Piece to the mufflers.

The rear may be restrictive on the 5.0 but way better than the stock IS350 mufflers. The main reason was looks and keeping it quiet without the dreaded Commodore V6 farty sound.

With the tune,HF cats and exhaust, power increase was more than 28 so I am more than happy with that. -4 tenths and nearly +4 mph is awesome. Can't wait for the PPE headers to arrive.....

yes midpipe is good design 

the rear section is not

Might be less so that the standard IS350 ones ??

oh yah def less than the 350s

but for what it is 

isf are restrictive as hell

just replace i with a 2nd hand unit

200 to 300

intresting how you went with the ISF rear mufflers

they are restrictive as well

have you actually physically tried? or just saying it doesnt fit cuz its different part numbers

as far as i know

IS200/300/altezz RS200/AS200 is all the same

if problem persist youlll need to get a new nav unit

\itll be around 600-800 used

as long as the bellhousing is for a JZ itll fit

is200 and is300 HU are exatly the same 

and so is the bypass harness

its not a sensor or anything

its the secondary cats on the exhaust 

take it out or replace the mid pipes and youll be good

the mirror itself is physically different 
LHD and RHD are different in glass as well

So how about performance and maintenance of GS 350?

best answer is go test drive one
for performance
maintanence is just like any toyota/lexus

spare are available for 10 years after them model production is finished
so 4gs was killed off in 2020 so you have untill 2030 untill parts will be made new as a minimum 
toyota/lexus still makes parts for older 2nd gen and even 1st gen IS as well which is now nearly 20 years old

well lets start with can you post a pic of your car?

front end pic plz

also what grade is it?

the f sport ones are 2 piece from factory

if you wanted to save money and upgrade you can go DBA rotors for normal is350 and Rc350

its not 2 piece rotors but least u upgrade the rotors and go slotted

oh and not metnion much cheaper at atound 200-300 per rotor
