06 v-maxx Posted February 7, 2011 Report Share Posted February 7, 2011 I just stuck my 112 on my truck this weekend, and now im thinking i need to upgrade my exhaust from stock. Has anyone had good luck or made decent power with a set of long tubes and the stock catback? Is the stock catback to restrictive for F.I. As of now with a 3.0 pulley im making about 8# of boost which tells me i have got some restriction. I need some ideas. Quote Link to comment Share on other sites More sharing options...
silverado777 Posted February 7, 2011 Report Share Posted February 7, 2011 There wouldn't be any point in doing LT's with the stock exhaust. I'd go with OBX LT's which have fake cats. http://cgi.ebay.com/ebaymotors/OBX-Headers-99-05-Chevy-Silverado-Denali-6-0L-V8-SUVs-_W0QQcmdZViewItemQQhashZitem256108d0a3QQitemZ160541757603QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories#ht_2147wt_939 then use your stock pipe, cut off the muffler and weld in a magnaflow muffler. Cost about $600 to $700. Will sound mean and flow great! Quote Link to comment Share on other sites More sharing options...
bruiser04 Posted February 7, 2011 Report Share Posted February 7, 2011 8lbs sounds about right for that pulley but u def r a lil restricted with back pressure Quote Link to comment Share on other sites More sharing options...
06 v-maxx Posted February 7, 2011 Author Report Share Posted February 7, 2011 Ok i already have dynatech headers from my old truck but they have the 5.3 y-pipe. Im thinking about getting the 6.0 pipes for the dynatechs just because i already have the headers. would a D.I S.O magnaflow work well? Also thought using the 5.3 y-pipe and doing a single 3'' exhaust all the way. Quote Link to comment Share on other sites More sharing options...
bruiser04 Posted February 8, 2011 Report Share Posted February 8, 2011 i would go true dual with 2 magnaflow muffs. its easier for it to breath Quote Link to comment Share on other sites More sharing options...

Jordan836 Posted February 9, 2011 Report Share Posted February 9, 2011 I wouldnt waste money on getting 6.0 pipes for the Dynatechs you can make that 5.3 Y pipe work with some cutting and welding if you have the dynatechs id use them they are awesome headers. And dual magnaflows would sound awesome! Or you can have a shop build you a custom Y pipe or also with some welding you can hook the Dynatechs up to your stock Y pipe if you cut the cats out. Theres a few options but if you have dynatechs Id definitly use them! The maggie will like them. Quote Link to comment Share on other sites More sharing options...
