Thank you. You have rated this product.

The Boss Frog "Straight Cat" is an unrestricted 2-1/2" 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 offroad race vehicles only.

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.

BRIAN'S APPLICATION NOTES: Unless you actually enjoy arriving home smelling like gas this is NOT a good idea for your street Miata. Also, please don't fool yourself into thinking you will get more power in your normally aspirated 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 racetrack Miatas and is legal for race cars only which may never be used on the highway.

SORRY>>>NOT FOR SALE TO CALIFORNIA RESIDENTS.

Includes gaskets and mounting hardware. MADE TO ORDER, ALLOW UP TO 10 days to ship.

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!
