What do Exhaust Headers do?
Upgrade your 2001-2005 Lexus IS300 with FLASHARK Exhaust Headers to boost horsepower, torque, and improve exhaust flow. These high-performance headers can add up to 15 HP/TQ, giving your IS300 a more aggressive sound and better engine efficiency.
Installing headers and an exhaust system not only enhances power but also improves fuel economy. On average, you can see a 0.5 mpg improvement in gas mileage. With gas prices around $3 per gallon, driving 15,000 miles annually could save you $85 each year, enough to nearly cover the cost of a complete cat-back exhaust system over five years.

Exhaust Header Vs. Manifold: Which is the Better Choice?
When upgrading your 2001-2005 Lexus IS300, choosing between exhaust headers and manifolds is crucial. Exhaust headers are made from lighter, thinner steel, while manifolds are heavier and typically made of thick iron. Headers are longer and provide each engine cylinder with its own tube, eliminating back pressure, which manifolds often create. This reduction in back pressure allows for better exhaust flow, boosting engine performance and efficiency.
For your IS300, replacing or upgrading to exhaust headers is essential for both improved horsepower and a more aggressive exhaust sound. Whether on the street or the track, FLASHARK IS300 Exhaust Headers provide easy, direct bolt-on installation with no modification needed, offering significant performance gains.

I ordered this header as a temporary replacement for a cracked "name brand" header. I'll be completely honest, due to the price I was not expecting anything great but I was surprised, it's actually pretty good.
I did have a hard time fitting the header. The two banks weren't spaced far enough apart so I did have to use a big pry bar and hammer to get bank 1 into the studs. After this, I was able to zip the bolts into the studs with no issues. The header did seem just a touch shorter than the "name brand" header I had before. Neither of these things were an issue for me, for the price it's about as great as I could have expected. Build quality seems on par with the other header I had and the O2 sensor locations are actually better (perfect IMO) on the flashshark header.
I don't expect the included gaskets to hold up forever, if I am able I will update this review next drift season.
I did wrap the header with DEI titanium heat wrap, the "polished" finish looked great before wrapping.
All In all, I bought this header for temporary use, but I'll be using it permanently because it seems like it's going to be completely fine, in fact better than a "name brand" header.
You will most likely struggle a little bit during install but for the price (which is REALLY GOOD) it is completely worth it.
I would recommend this header to a friend and I would buy another!

Enjoyed and admired the quality of the product. Had slight issues with the shipping but with one email stating that I haven't received my package. They was able to contact me via email and was able to send a replacement in a quick and fast shipping speed. So although there was complications, they have made the effort to compensate for the inconvenience so 5 stars overall.
