Thank you. You have rated this product.

Sorry, this product is not available to residents of California.
This Stainless Straight Pipe is an unrestricted 2-1/2" stainless pipe coupled with two heavy duty flanges that bolt right up to your exhaust in place of the stock cat.

Not CARB approved and never will be, legal for off road race vehicles only, NOT for sale to residents of California.

YES, this will bolt up to anything your stock cat bolts up to, that includes stock exhaust and stock header and any of the aftermarket headers or exhausts we sell.

Proudly made in the USA, all Stainless Steel has lifetime warranty.

BRIAN'S APPLICATION NOTES: Please don't fool yourself into thinking you will get more power in your street Miata by going to a straight pipe. It was true three decades ago that the original pellet style catalytic converters were very restrictive, the modern monoblock core converters are NOT and making this change on your street Miata instead of using one of our highflow replacement catalytic converters is only going to get you the stench of unburned gas while you sit at stoplights.

Therefore, this mod is for the true race cars and is legal for race cars only which may never be used on the highway.


Includes fresh gaskets and hardware.

I absolutely love my Roadster Sport headers, mid pipe and Q muffler. I have owned a lot of cars over the years and the quality of your product is truly exceptional. The ability to tune the Super Q is very much appreciated.

First I want to again thank you for working with me on this muffler. I have almost 100 miles on it now, and it has a nice mellow sound. a little Bass, but not too much. A little louder than stock, but not too loud. Plus it is nice inside the car with the top up. I am happy so far I bought this one.

I belong to a local Miata club, and am very active with it. When Spring comes I will tell everyone how much I like the muffler, and how great you are to work with. Maybe I can get some extra business for you.
