My Lexus is300

They so good and good welding
I really recommend to buy

Bit of a complex install but besides that it fits perfectly and it sounds amazing!!

01 Lexus IS300 HEADERS

Bolted right into my 2jz-ge 01 Is300, didn’t have to hammer or do anything to my firewall, all o2 sensors fit in the right areas as well, amazing product in my opinion.

Great product and it sounds amazing in my 2020 si!

Easy install 1 for 1 swap

Catless downpipe

Fits great, hardware invludes is a lil wide to use downpipe support brackets but you can make it work using assortment of the factory bolts and nuts, sounds good, good welds and after a heat cycle or 2 the downpipe is a beautiful burnt titanium look to it

Good product, just a little adjustment needed

Bracket near flex pipe needed to be bent but happy with the product

100% great service, friendly people, and great products

I recently ordered a catless downpipe for my 2014 ST. Package arrived within 1 week, which is great considering it had to be shipped all the way to New Zealand. Jaden is a great help and was so generous to throw in some extra goodies. 100% recommend.

Intake Manifold and Throttle Body Spacer

These are great looking parts, came quick and fit great.

2007 Subaru Wrx STI here! The fit, finish, and quality is AMAZING!!!! One of the bolts toward the passenger side wheel is tough to get a nut on the other end of the bolt due to how big the bellmouth is on the downpipe. The bolts are self-fastening in so it worked out in the end! The Zinc coated nuts and bolts are my favorite!! Very high quality and the bends and design of the downpipe itself are perfect! Highly reccomend this product! The customer service was awesome too!
