Megan, OBX, Toyomoto, Alphawerks, JVT, are all copies from one another

OBX does have a short runner header as well

Mazzuri were its own design

all long runner headers will give you top end power, while the short will give you more mid range

as for price all except the Mazzuri should be in the $200-300 range

 

Everyone i have heard from they state how mazzuri headers are the best but i can't find them anywhere.

 

Daniel, the owner and maker of Mazzuri has closed its doors.

Before he closed, he made 2 sets of headers for the IS300. V1 has flanges, V2 is a sleeve type and from what I heard. It was the best he made.

I wouldnt spend more than $300 on a set of headers/ypipe.

Its not worth the minimal hp gain you get from a Mazzuri.

Good Luck and happy modding

 

just go boost :-P save your money

 

I'm debating on headers also but it seems they don't really provide a lot of benefits for these cars. I've had several Toyota pick-ups and they really woke up with headers.
Maybe boost is the better way to go with the IS

 

There is upside for NA bolt ons, while there are downside for BOost. Just do your research, and find which way is better, in the condition you want your IS to be in.

I chose NA route. I hate down time, when my IS a DD

Just remember, you wont get over 250whp on NA
I/H/E, 80mm TB, Cams, Gears and all the electronics you need to get the max hp/tq.

Boost is everything on that list, minus I/H/E. Which you could save up to $1000 or more. Depending on the brand you would have gone with. Just dont try to start NA then decide to boost. Your savings will go in the toilet, along with your wallet.

 

yea i would not get headers if ur gonna stay NA.. the IS is slow even with power adders.. u wouldnt want a *LOUD* slow car.. i know i hate loud slow cars...

save ur money and go BOOST.

 

Since you're in the wonderful state of California, I don't think any of the headers are CARB approved. Pita when you have to smog, unless you know people.

 

Ya i bought an easy button and know people

 

i would probably go with xerd....

 

Hey this is Robert in San Diego, I've seen you on sdrev.

anyway, let me know what you end up getting so I can check it out.

I currently have a set of ebay headers for my SC, but not installed yet.

 

authentic alphawerks for $100 shipped. woot.
