How a lexus isf should sound....

[stuno1]

The sound and fake tips on my isf frustrated me a bit. So i ordered Takeda intake from America and got hayward and scott to fit a cat back system with real tips. It makes such a massive difference. Nice rumble on start up and low revs and amazing sound under acceleration.

Sounds good but the dyno results from the US don't reflect well on the custom intakes.

[stuno1]

Yeah, read in to that before doing mine. Just done it for sound benefit to be honest.

how much difference does the intake make (sound wise)? been looking at these and wanted an honest review!

[stuno1]

I like it chap. I don't have a clip with it compared to stock as I had my exhaust fitted first.

What I can say is it is louder and sounds great. Provides more of a growl and I love it. Also maintained the 2 stage intake which some intakes get rid of.

I've been idly trying to find ways of adding about another 100 or so horsepower to ours, doesn't seem easy or cheap! And probably foolish!

[stuno1]

With no maps available it would be very expensive. N/a cars are always hard to get more power from than turbos.

The IS F is hard to tune as (AFAIK) it's not possible to remap them.

So while you can fit various options typically without the remap to support them they actually lose power compared to the stock systems.

My cat back and intake will have little or no impact on BHP figures. I did it purely for sound.

If you had the intake and did a full system replacing the cats with high flow sport cats, removed the silencers after the cat, made the back boxes smaller and added freer flowing headers there is approx 50BHP to be had according to the US forums.

Personally i am not bothered about another 50ponies for th ££££ outlay to get them.

Yup, if you want to tune an NA Lexus then the smaller engined cars are far better understood and with their Toyota heritage the engines have way more power options including forced induction kits.

Assume that was your dad coming over and smiling?

Mine would have been banging on the window telling me to "turn it down!"

Sounds good btw

It was indeed my dad. Wanted to take it for a spin.
