The offset Porter Muffler offers two options for your offset needs, 11 degrees, and 17 degrees.  The offset Porter Muffler is handmade using heavy-duty 16 gauge aluminized tubing. The stainless steel Porter Muffler is handmade using heavy-duty 16 gauge, highly polished aircraft grade, 304 stainless tubing. Our uniquely designed interior chamber is fitted with a gapped steel spiral core and packed with stainless steel wool to channel the exhaust and make that distinctive Porter Muffler sound. To continue our tradition of quality, each Porter Muffler is handmade using only the best heavy gauge and high-quality steel products sourced in the U.S.A.

Picking The Correct Offset Mufflers– If you are currently using a flat, oval-style turbo muffler and cannot change the existing pipe routing to accommodate, the "Shorty Offset" muffler is the solution to this problem! Determine if you are in need of an 11 Degree or 17 Degree Offset Porter Muffler using the diagram below to help ensure the proper fitment.

Best sound period!

I put these on a big block 396 and they are perfect. No drone cruising. I didn’t want a quiet muffler either. These let you hear the power when you want. Very awesome sound when you get on it. Couldn’t be happier.
One thing to note, you need videos of big blocks with shortys on.

Thanks for the review mike! We will share this photo you sent on social channels!!
