Got a question?


Hey Andy,I bought an Over the Top header for my 71 type III squareback and am looking for a replacement muffler. ISP West referred me to you. Thanks in adavnce

Hi Matt,  Please keep in mind that the “Ask Andy” part of our site is for technical questions.  This is a sales question.

That being said, I still happy to help!  We sell TriMil exhausts.  The T3 over the top system is a #1013.  The replacement muffler only for this system is a 1013M in black and 1013M-PC in a polished ceramic finish.  I did just check our web site, and much to my surprise, these part numbers are not on our site!  I am working to get them posted ASAP.

I hope this helps,  Andy
