Freddy made a deal with Tony and now he has to install a header on his IS300, the cheapest one Tony could find on ebay. How's the fitment, build quality and sound? Lets find out!

The rattle/rasp is part of the header. You can't do anything to make it go away. I figured this out from months of research. It's not actually a rattle or anything loose. If anyone cares.

Finally someone who knows how to do proper drive buys for the sound.. 👍

[@PoorManMods]

Thank you 😊

[@tokengarage43]

IMO IS300 HKS axle-backs are the best sounding by far- they sound good with almost any upstream mods be it OEM or a mix of header/y-pipe combos.

[@imustbepsychic.]

Love your comment about how to record an exhaust sound! I die a little inside every time my beloved floor standers try to replicate the diaphragm on someones mic distorting. Spread the word :)

[@PoorManMods]

I literally made a how to video a few yeara ago. The world needs to watch it kzbin.info/www/bejne/r3qwg3mldpiqitU

[@litgeeksquadofficial]

Geat job on recording the exhaust sound, so much better than many videos ive seen. The tin can sound could be from the metal on the headers being so thin, i would maybe try wrapping it and see what that does. Also, ive seen vids on diy drone reduction mods, maybe something like that could help tune the tone

[@danielgalan6518]

Awesome vod man! Keep up the great work you're amazing!

[@PoorManMods]

Thank youu!

[@JayJay-du4tp]

I ran Apexi N1 cat back exhaust with Alphawerk headers in 2005. Had to remove the header because it was TOO loud. I believe Alphawerk was one of the first company to make IS300 headers.

[@MannyIsTHEGamer]

i have the same headers but for some reason when i tried to connect it to the y pipe it was misaligned?

[@JackAttak]

Great video. Thanks for the notes about the install and 02 sensors. eBay headers are usually problematic - when I ordered a set of $50 headers for the 5S-FE in my 92 Celica, they showed up with one of the pipes not even welded lol

[@overbuiltautomotive1299]

still a deal sadly i been looking for header long tube ford 460 BBF and 1200 for i assume usa made stuff sucks price is nuts and no china junk but oh well lol a kit would be nice and are around made in usa with you guessed it nutz oh pricing

[@heyhayhay247]

I got really excited when I thought this was for the IS-F. That thing is just begging for a good set of headers.

[@DIY-Mark-3]

I have this manifold on my nonvvti mkiii supra but my setups is gte pistons and a 27mm head gasket and full 3inch straight pipe which was crazy loud. So now i added single muffler at rear. People constantly compliment the exhaust note. Probably the low compression makes it sound deeper. I still want the car to be little bit more silent so ill be adding an second middle muffler. Oh I build my engine low compression for future boost.

[@PoorManMods]

niceeeeee

[@ronaldhino52]

[@christophersuttle4007]

You didn't need to buy a o2 sims??? How's the car running

[@PimpedPrevia]

If you still got the OEM resonator it does an awesome job to muffle down the rasp and droning. I've got and Megan header, midpipe and Dynomax axle back, stock resonator. Not obnoxious at all. Here is a sound clip. Not the best sound quality was recorded with a SJCam kzbin.info/www/bejne/bGmZi6OEq71kqbs

[@DIYAUTOCAR]

I had one of those on my first IS300. Although it was 2014 or so and the damn thing was like $250 back then and the rear o2 was hitting the firewall..... No other sweet $60 options like they have these days.

Did you use the supplied gaskets? I recently installed a set of headers on my IS300 and it’s leaking at the engine and at the y pipe ☹️ My mechanic is saying it’s the cheap gaskets but I’m on the fence about trying new OEM gaskets or putting the OEM exhaust manifold back on because I can’t deal with the sounds the cars making from the leaks. Any advice? Thanks!

I reused the OEM gasket

[@RubMySchmeat]

Yo my man just go to your local Toyota or Lexus dealer they get them

hey im having trouble with and exhaust leak right where the headers meet the y pipe because the headers has a flat flange instead of the donut shaped gasket, how did you over come that?

keep the rest of the exhaust stock and it should sound decent

[@RCAndroidFreakCz]

What's your opinion on those headlights?

[@PoorManMods]

i LOVE them! did you watch my video on them?

[@withoutfathom8925]

I agree with your opinion, so no offense, but I don't like the sound of this at all 😂 With that said, I'm slightly spoiled, cause I think I have one of the best sounding is300's out there. And no crazy exhaust setup; the main thing that changed it all was removing the 3rd catalytic converter, the "Cali Cat" lol. All the sudden it opened up and sounds close to its true 2JZ tone! Stock header, never touched it... But I am now seriously starting to look into replacing it, simply cause it's wearing out and rusting up; hence how I came across your video. Been watching for awhile tho, so always appreciate the "poor man's" perspective on this car, so thank you as always for the work. BUT - my '04 is non-turbo, and I don't believe anyone can change my mind on how amazing it sounds with such a simple and relatively inexpensive modification that any decent exhaust shop or DIYer could do! I don't have great sound clips, but one day when I get my car to where I'd like it to be, I'll do a video on it.

Like what you’d expect from BMW or Ferrari even.😱😂 Figs also makes a full titanium exhaust for like $4 grand../holy fuk! I always dreamed of a full titanium exhaust.

Even the High quality headers like Megan don’t make any REAL power on the VVT-I 2JZ-GE. We all know it’s VERY expensive to make real power with any Naturally aspirated engine. The only IS300 2JZ headers I’ve seen that make any real power are then newer Figs and they’re obscenely expensive($2400 without any coatings…holy shit). BTW It’s not rocket science with respect on the exhaust. Without a resonator it’s to loud and it rumbles(backfire sound) to much. A great muffler like the HKS HI-Power with a resonator sounds great and it’s not to loud. Whenever I do headers I ALWAYS keep my stock manifolds.💪🤘👍
