You are bidding on 1 pair of our 7" stainless steel chambered mufflers. These are the shortest and loudest versions that we make - use them as mufflers or help change the tone of your exhaust as resonators, by using them back towards the tail pipe. This is a hand crafted/welded muffler made right here in Michigan at HighFlo Performance.

Overall length (with nipple ends) - 11"
2.5" inner baffle
3" outer casing
2.5" ID inlet
2.5" OD outlet

We will be happy to expand the ends up from 2.5" to 3" if you desire, just specify in your order notes.

We build everything from scratch here at HighFlo Performance in Michigan and are proud to have a made in the USA product.

Also we can build any chambered muffler in length, if you have a custom job we can do it!
