VinhZXT Posted November 20, 2006 Share Posted November 20, 2006 Hi All, I run into a little of problem with my side pipes. I bought the FFR side pipes and after cutting them up for modification I found the inner diameter of each pipe is only 1". I also got some feed back from FFR members that these side pipes are very restrictive. So I want to build my own side pipes now. What I want to use are 2" straight thru pipes. Then slip a sections of a 2 1/2" pipe over the 2" pipe. Stuff a lot of fiberglass in the gap between the pipes then weld the ends shut. Typically I am building 2 silencers on each side. Also do I need to drill holes in the inner pipe (the 2" pipe) so it will absorb sound better? Opinions/ideas are welcome. Thanks Vinh Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted November 20, 2006 Share Posted November 20, 2006 Wouldn't it be a lot easier to get a 2" glass pack muffler and install a shell around it. The fabrication time would sure be a whole lot less. Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted November 20, 2006 Share Posted November 20, 2006 so you are doing a shelby daytona coupe copycat? Very cool. Just get two, 2 inch "purple hornies" from summit and then paint them black. Quote Link to comment Share on other sites More sharing options...
VinhZXT Posted November 20, 2006 Author Share Posted November 20, 2006 Thanks for the info. I have searched every where already and no one sells 2" glass pack that are longer than 24". The 2" glass packs they sell actually have 3" outter diameter. I am looking for 2 and 1/2 " outter diameter. 2 3" glass pack on the side of a Z will be way too big and bulky. Here is the look I am going after: Quote Link to comment Share on other sites More sharing options...
rytherwr Posted November 21, 2006 Share Posted November 21, 2006 V..you don't like the looks of the ones on my hot rod? Pic attached Wayne Quote Link to comment Share on other sites More sharing options...
VinhZXT Posted November 21, 2006 Author Share Posted November 21, 2006 Wayne, Yes I do like the ones you have on your Z but I want mine to somewhat ressemblance the original Daytona Coupe. The twin side pipes are unique on the Coupe so I want to have them. I actually installed the Dynomax side pipes similar to yours on my friend's Cobra. This is because he likes the way they look. At one point I was going to install these Dynomax sidepipes like yours to save me time, money and headache but I thought about it and I decided to stick with the original plan. Time to do some research on silencers. Vinh Quote Link to comment Share on other sites More sharing options...
rytherwr Posted November 21, 2006 Share Posted November 21, 2006 Got it, V...good to go...Although the only thing left of the original Dynomax is the outside chrome stuff....I replaced the crazy 1.5 inch inside ID mufflers with full 3 inch race mufflers. Good luck on your hunt... Wayne Quote Link to comment Share on other sites More sharing options...
VinhZXT Posted November 21, 2006 Author Share Posted November 21, 2006 Wayne, Do you have a sound clip of your exhaust? Can I hear it? Thanks Vinh Quote Link to comment Share on other sites More sharing options...
rytherwr Posted November 23, 2006 Share Posted November 23, 2006 I don't have a clip at present, but I will make one and post, probably tomorrow. Wayne Quote Link to comment Share on other sites More sharing options...
