Default My ISF Gutted Primary CATS Vs PPE Headers



PPE Headers {Ceramic Coated}
Hi everyone, I installed the PPE Headers on my ISF two days ago, with the help of a friend, and it took us around 6 hours. I did make a short video comparing the interior sound of Gutted primary cats Vs the PPE headers, also this week i'm planning to install the RR Racing Tuned Intake, and re-tune the car. I will update you when all set.
Note: Try to use a good Headphones for comparison.

Nice comparison video between the two. After poll hitting on headers, did you feel any performance gains?

It's louder, and you can hear the rumble sound.

It seems that you are driving around the Detroit area, I am right across the state border in Toledo. Lets meet up and cruise sometime!

Cool comparison. I know most of these times the videos/recordings just dont do the real life sound experience any justice.

I have a catback but with cats and it sounded great like most ISF's. When i went completely catless and got PPE's fitted, the sound was night and day.

Its not one of those situations where you have to force yourself to hear a difference, its louder and as the OP said, you can hear the rumble more. It unleashes that exotic raspy sound. Both car and not car friends could all hear the difference without them knowing prior.

Power increases are there but more so once a tune is carried out

You are absolutely right, and i did install the RR Racing Tuned intake, and re-tuned after this Video.

It’s kind of neat having such a throaty and loud Lexus. All the time people approach me to ask what engine and / or car I have after they hear it running. I love it.

Congrats on your newfound power and sound.

Hi guys .Sorry I don't have an F but I would like you to saw me a pic (if you have any) of your gutted primary cats.
I have a 2IS supercharged and I deleted my primary cats and unfortunately it made a horrible sound when I accelerated so I put them off.

agreed. Best car for the money IMO and you can enjoy it for 15 years if you really wanted too before it would get tired.
