Lexus IS200 Japspeed Decat Exhaust Manifold Installation! [Full Japspeed Exhaust System]

The decat Japspeed manifold is a beautiful looking exhaust manifold! In this video I'll show you how I installed it into my Lexus IS200!

Be warned... it's LOUD! xD

If you have a stock exhaust system, you should be okay. But if you have a sports cat or decat pipe with a cat back, this will be extremely loud. For a daily driver, I certainly wouldn't recommend it! :D

NOTE: THE BEST SOULTION TO THE PROBLEM IS TO REWELD ANOTHER BUNG INTO THE CORRECT POSITION. If you don't want to do this, I suggest not purchasing this manifold. Thanks for watching!

Amazed by the quality and effort you put into this, wish it were around when i fitted mine! 😂

[theunicahijaph]

I'm always so relieved when it starts up and doesn't explode 😂 But the car really did sound obnoxious with that, especially on long drives, so hopefully it's a lot better now 👌🏼 Good job!! The happy noises you were making on the drive means it was a success ❤️

Well that answered my questions of "surely that will be loud as with your current system" and "will you really not get an EML with that?". Hope you keep doing vids if you continue with your plan.

Great to see you still awnser on your videos mate. I actually have a question. I am thinking of getting only the Cat-Back system. At the end you explained that the bung should be rewelded. Did you have any check engine // problems with just the catback and an angled adapter at the back? Or did the problems arise due to the manifold install. Thanks for your time. Greetings from Germany

Great video. How can they sell the manifold as "for IS200s" if the O2 sensor hole isn't in the correct place?
I have a spare 200 Sportcross manual I intend to track, I know there won't be noticeable performance improvement but I want to "mod" something other than led lights haha.

I know you returned it 😂, but it sounds so good

[carlospineda]

Excellent work and explanation. Where did you buy the headers for the 1G-FE, I have one and I want to put a headers like that on it. Greetings and thank you very much.

Why would you need to change exhaust in order to put in a supercharger?

I had a few such plans myself, but my engine is burning oil, as the 1gFE tends to do. Don't want to supercharge it before I know the piston rings are OK. Burns about 1 liter per 3000 km, I guess about a quart every 1800 miles.

Cool vid🎉 how many o2 sensors does an is200 have 😅

The link for the 02 adapter is no longer useful . Would you be able to provide info on the particular adapter you used?

[NoBodyNoNose]

Did you ever install the supercharger on this car? And if so, would/does the sports cat impose any problems compared to a decat?

[RoriTwinTailedFox]

After some use how was the sound of the car good or was it annoying after awhile

[silentftw]

Next vid install k&n air filter and turbo???

[aksdan]

Do I have to remove the steering u joint to get the old manifold out ?

[BudKing]

1:50 would i need to disconnect battery just to replace exhaust manifold gasket on stock system? Would it mess with o2 sensor at all throw codes/EML?

[foscmindscape]

Month ago ago i just gutted my stock manifold and welded some cheap japcan on the back as stock one rusted off. Still not too loud as my charger whines more than exhaust.

[macnoelimanil]

where do you get the adapter for the o2 sensors or does it come with the decat ?

[blunt-trauma]

Did your check engine light come on after the decat manifold was fitted?

[hamzazekagh]

Hi mate, you said you were getting an is300 would you be selling this is200 ?
