This test pipe is made from 100% pure titanium! Ultra-light weight for pure performance results. The extra bonus is that this titanium test pipe will change color to a nice sexy blue over time from the heat.

Because this product replaces/removes an OEM emissions control device we must state that this product is for off-road use only.



Great product

Easy install. With lift it literally took 5 mins.. The car is notably deeper and sounds super aggressive, better throttle response and has brought back joy when driving again. The design is beautiful, fits perfectly, and weighs close to nothing. Amazing product, would buy again.

Tomei Expreme Ti Test Pipe

I recently purchased and installed the TP on my 2013 MR which already had a stainless steel TP on it. The steel TP that I had did not have the bend that the Tomei TP had and as a result broke the factory rubber hanger. The Tomei TP not only has a bend in it's design but does not even use this rubber hanger due to it's superior fit and light weight i'm sure. The Tomie TP is far superior in its construction and design and I couldn't be happier. The weight savings are a added bonus on the beefy EVO MR.

I recently purchased and installed the Tomei TP and I must say I was impressed. The construction of the TP was excellent and the weight savings was impressive. The installation was very straight forward, especially as I was using a different stainless steel test pipe. Installation took maybe 10 minutes with the assistance of a lift.
