FAQ - Frequently Asked Questions
Are your exhausts street and/or smog legal? Do your catbacks have CARB exemption numbers?
The vast majority (over 95%) of our exhaust systems are smog legal.
Some of our exhaust products are race products designed for racing or off road use only, please check with your local and state laws.
Catback exhausts do not require CARB exemption because they are bolted after the catalytic converter and maintain stock exhaust routing and sensors.
What is the difference between Tsudo exhausts and other brand "x" exhausts?
Tsudo exhausts are all made completely out of T304 stainless steel, the best stainless steel in the industry.
Other and "brand name" companies may use aluminized mild steel, painted mild steel, or cheaper stainless steel to save costs.
Tsudo exhausts are also all constructed with mandrel bent tubing.
All the mufflers and resonators used in the exhaust systems are straight-through design, having good muffling capacity while producing the best performance.
Why is T304 stainless steel better than other types of steel (mild, aluminized, T430 steel)?
T304 stainless steel has the highest corrosion resistance compared to T430 and other grades of stainless steel.
It will never rust and is the strongest steel for use in exhaust systems.
Painted mild steel and aluminized steel will eventually rust/corrode and fail over time when the coating of paint/aluminum easily corrodes through
Why is mandrel bent tubing better?
Mandrel bent tubing has a uniform diameter throughout the bend, a 2.5" mandrel bend would be 2.5" all the way through.
This keep performance up and exhaust flow high and efficient, maximizing the performance potential of the system.
A crush bent pipe is literally crushed into a bend, making the diameter smaller where the bend is made.
A typical 2.5" crush-bent pipe could only be 2" in diameter (or even less!) at the bend.
A picture of a crush bent (left) and mandrel bent (right) pipe is shown below.
Why can't I just have any exhaust shop make an exhaust system for me?
A mandrel bending machine easily costs in the tens of thousands of dollars, so most exhaust shops can ONLY make crush bends for their piping.
This results in piping that won't perform as well as a mandrel bent system.
The typical neighborhood exhaust shop also would not stock high quality stainless steel piping.
The low quality aluminized steel that is normally used will rust and corrode from the moisture and heat in the exhaust system and is not as durable as T304 stainless steel.
How hard is it to install the exhaust system? Can you install it for me?
All of our exhaust systems/components are built for straight forward installation with just hand tools.
ALWAYS use jack stands and wheel chocks on level ground. Safety should always be the first priority when working on your car.
We do have installation services for customers that pickup from our location.
