you guy have been asking for this for awhile now and I have been saying it is coming so here it is .I had a customer test it he said it is just a little louder .This will also be offered in a Cerakote ceramic coating that reduces heat up to 400 degrees. Right now I still have not got this flange figured out so I'm buying the oem primary muller and stealing the flange .so the price will reflect that or you can send me your primary muffler . contact me direct if you are interested rlsexhaust@yahoo.com or 469-878-5166
