Thank you. You have rated this product.

This is a modified version of our all helmholtz Super Street muffler that adds small chamber dual tip muffler to add lots more user control, FIVE different sound settings with the included baffles, TEN different sound level variations if you mix in the optional packed baffles. Nonetheless, this is a VERY aggressive muffler by design with roots in our RACE muffler, except the chamber makes the sound more lower register, with more bass notes, and even with baffles installed it is one of our most aggressive choices.

UPDATE 10th November 2016, we are including a third baffle with shipment, which is the blocking baffle that effectively converts this muffler to same sound as the Race muffler, adding back in the higher frequencies the chamber would otherwise convert lower (to cover the costs of adding that blocking baffle we are ending the RoadsterSport script on the tips). Result is more choice and control over the result than any other choice.

Separately on the site is a fiber packed long baffle that effectively converts this unit to same frequency balance as the SuperStreet Single Tip. Thus, now essentially THREE mufflers in one here, the Race with included blocking baffle, the SuperStreet Single tip if you add packed long baffle (item 60-1325SSTT), or skip the long baffles and use standard length baffles in one or both tips (item 60-1324T) to keep the bass heavy frequency balance but lower the volume. Result is a 16.9 pound street muffler with MORE flexibility than all other choices.

You get the great look of the RoadsterSport rolled and polished twin tips, the clean flow of the shortest possible path from the midpipe to the exhaust tips to max your horsepower gains, unprecedented level of user adjustment...and minimal weight with these features.

What the baffles add is much more ability to tune the frequency balance of that result, left rear tip pathway is essentially a straight through and adding short baffles back to that pathway reduces both higher frequencies and volume, adding baffles to both pathways further reduces overall volume, adding long baffles to driver's side tip cuts off the chamber and massively lowers the bass notes and raises the upper frequency response, etc.

SHIPPING NOTE...ships factory direct to you. All POLISHED stainless steel construction. Uses stock hangers and connects to either our RoadsterSport midpipe or the stock midpipe.

Again, the SOUND level is Adjustable by YOU, INCLUDES pair of removeable cone baffle inserts factory installed in the tips that help YOU select final sound level, baffles in for reduced sound levels, and baffles out for more sound, plus a long blocking baffle to cut off the muffler chamber and leave just the Helmholtz chamber function which duplicates sound of our Race muffler (More treble, MORE overall volume, but massively less bass frequency).

Just one bolt under each tip to make the baffle easy change. Sold separate are standard length optional packed baffles that cut the sound a little more if you want (and 60-1325SSTT long packed baffle that bypasses muffler chamber like the included long blocking baffle but with packing to reduce volume and simulate the frequency balance of Single Tip SuperStreet).

Proudly made in the USA...with a LIFETIME WARRANTY!

BRIAN'S APPLICATION NOTES: Without baffles almost mild when cruising on otherwise stock ND, delivering a DEEP BASSS THROATY RUMBLE when you wind it out to redline, lots of fun burble when just playing with the throttle around town. NOTE we have report this does NOT clear our harddog hidden hitch or Velox rear diffusser!

BRIAN'S INSTALL NOTES:

Installation of this Miata exhaust is SUPER EASY...just two 14mm bolts to loosen! When you open the big box you will find separate foam wrap on the exhaust tip, leave that foam around the tip during your install to protect the polished tips and your car's soft plastic in the exhaust cutout. Use gloves. Note the 'bolts' from the factory are actually studs with springs and nuts and the factory usually jams the nuts on so hard that unbolting it will bring the stud out too. If that does not happen then use 13mm long socket to unscrew the studs (or use jam nut technique where both nuts are put on one stud against each other and then wrench used on the inner of the two to back out the stud). Then lube up the stock exhaust hangers with dish soap and yank stock muffler back and forth to work the soap into the rubber hangers and then the muffler will slide off those rubber hangers easily. Then hang the new muffler on the wet and soapy rubber hangers and torque 'bolts' with the springs back in place to 30ft/lbs. Now you can remove foam tip wrap. Option to remove the baffle too, to do so loosen bolt that holds it from under the exhaust tip and use it as handle to shake the baffle loose and then unscrew bolt the rest of the way and pull the baffle (pulling baffle raises the sound slightly, I suggest starting with baffles removed). Note the muffler to midpipe joint is a ball socket connection for the first time on a Miata, it is designed to move a lot, so please do not add sealants that will gum up that dry ball socket joint.

Hey Brian, Recieved my Borla Dual Muffler Sport today from Fedex, and installed it in about 30-45 minutes. An Outstanding product with absolutely no drone throughout the power band, it sounds powerful, not at all like one of the ricey "fart tubes" that can be found elsewhere online. It has perfect like OEM fitment. Great prices, and great products. Product was shipped promptly and arrived as ordered. Would buy again!

RE: RoadsterSport Stainless MX5 Miata Midpipe Part# 60-1328: I love the mid-pipe!! Not only is it beautiful, but it makes the sounds coming out of the 'race single' exhaust even better. The two go well together, and it mellows the decel drone a lot. I'm very happy with my purchase.
