Here's magnaflows web site:
http://www.magnaflow.com/02product/s...ayproducts.asp Heres a roush kit: http://www.jegs.com/webapp/wcs/store...=mode+matchall By DarrenWS6: For a cat-back swap only, I also would suggest the Roush Off-Road. I still wish I had gone with it. The best performing exhaust is a 3" single for these trucks, with a 3" single tailpipe or dual 2.5" tailpipes. One of the absolute best set=ups would the the Dynatech LT setup with Magnaflow hi-flow cats and Y pipe ( avail. as kit for $1400 from Troyer ) to a 3" single exhaust with a straight through muffler. I noticed a little loss when I had my 2.5" true duals done. I had to have the sound though. True duals is not a good performance exhaust unless theres a cam and supercharger to back them up, otherwise stick with 2.25" for better scavenging. I couldn't bark the tires from a WOT punch after I got my exhaust, was able to again when I removed my rear converters, and i'm able to leave a couple black dashes with the Gryphon lol. In general terms, my suggestion would be run 3" from the Y to a straight through muffler of some type ( Magnaflow, Roush kits, Bassani, Borla.. ) end quote. Magnaflow probably makes the best kit and or components on the market right now. Last edited by 88Racing; Sat, December 26th, 2009 at 08:38 AM. |
