frostbite3360 Posted September 19, 2007 Share Posted September 19, 2007 About a month ago I had all this installed on my 2005 2.5i. The Borla header was actually designed for an older WRX, I think a 2001-2002 model. But it fit on perfect. The catalytic converter was made by Random Technology, and also matched with the header perfectly. I had Meineke run 2.5 inch pipe from the catalytic converter to the muffler on the drivers side, and replaced the stock muffler with a flowmaster. No more needless dual exhaust. No more resonator either. Overall, the sound is very aggressive, its unmistakably a Boxer sound. However, I'm getting some pretty annoying rattling. It doesn't get as loud sometimes as it does others, but it's pretty much there all the time. Is it because I havn't had my car tuned since all this, or is it the muffler's fault, or could it be a rock? I'll try and post a sound clip later so someone who knows what to listen for can hear it better. But any help would be appreciated. Link to comment Share on other sites More sharing options...
vet Posted September 19, 2007 Share Posted September 19, 2007 heat shields maybe? Link to comment Share on other sites More sharing options...
tommypenguin Posted September 19, 2007 Share Posted September 19, 2007 heat shields maybe? +1 easy way to check give your piping a good thump with your hand and listen... if you hear heat shield hit the piping, there's a rattle also, it could be your muffler tapping on the body metal. If your heatshield is causing the rattle, jack your car up, get a breaker bar, and flex heat shield out of the way, or you can cut it out of the way.... good luck Link to comment Share on other sites More sharing options...
CDN 2.5i Posted September 19, 2007 Share Posted September 19, 2007 is it a metal on metal ringing/rattling? check to see if the header is touching any hard lines under the car - mine was touching the power steering line... Link to comment Share on other sites More sharing options...
frostbite3360 Posted September 19, 2007 Author Share Posted September 19, 2007 http://la.gg/v/exhaust.wav Theres a soundclip of my exhaust. Thanks for the advice so far, I'll try checking the heat shields when I get a chance. Link to comment Share on other sites More sharing options...

CDN 2.5i Posted September 19, 2007 Share Posted September 19, 2007 Had the issue corrected by a muffler shop: they heated the header and tweaked it until it cleared the line enough so that it didn't rattle. Link to comment Share on other sites More sharing options...
