it works....

My 67 Mustang was too loud. I bought these to quiet down drone and decibel level. They did the job but there was a noticeable difference in power....

Great option

Worked and fit great. Put them on my 78 ford f250 with long tube headers. Ran 2.5 true duals straight pipes and it was to loud. These made it sound just right. Highly recommend.

Fitted snugly into collectors. You need to drill a hole in exhaust and weld or pop rivet to secure. Reduced noise level from 105db to 95. Still a great sound. Easy way to reduce a noisy exhaust. Probably restrictive if over 350hp
