Nice and well made.

July 30, 2015
I liked the way the louvers are in a spiral going down the inner tube. I modified mine to so that they where 2 1/2" in and out with turn downs.
Yes, I recommend this product.

Some difficulty in bolting to headers.

October 01, 2014
Some modification required to match mounting holes on headers. Not a direct bolt on. Mufflers seem to be well constructed.
Yes, I recommend this product.

I got what I wanted, priced right

December 15, 2010
Bolted it directly to a Model A header. When received the flange needed grinding and the paint was not high temp. When the muffler was repainted and installed it sounded excellent. Would I buy another one? Yes!
Yes, I recommend this product.

Is this 2 1\2 inch inlet pipe diameter or bolt to bolt flange measurement? Mine header measures 2 1/4 pipe but 3" bolt to bolt on the flange. Thanks

This muffler is for use with 2 1/2" OD collector flanges such as 91013369. These have a 3 on 3.06" bolt circle. The bolt holes will be 1.53" from the center of the exhaust pipe to the center of the bolt hole.
