moominer97 Posted March 27, 2013 Report Share Posted March 27, 2013 Flow masters is what I have. Not sure what series though. They are cut off behind the cab and have a nice tone. Not drowning in sound either. Link to comment Share on other sites More sharing options...
stroupe79 Posted March 27, 2013 Report Share Posted March 27, 2013 MagnaFlow are nice... I am running a 50series Flowmaster on my 3.7L and it sounds pretty good, could have gone with a 60series and probably liked it just as much... you can run 44, 40, or 50series on a Yukon here is a video of 50series on a Yukon...not too bad if you ask me http://www.stevemead...cherokee-build/ 2005 Jeep Grand Cherokee Alpine CDE-hd148bt Alpine PKG-RSE2 PRV Audio (4) 6MB200 front/rear doors PRV Audio (4) TW350Ti dash/rear doors Kicker KX350.4 Obsidian Audio (1) 18 D4 v2 revamp (2) Stereo Integrity HT 18d2DC Audio 1.2k5.25ft^3 tuned @34hz revamp Infinite Baffle Cpillar AudioTechnix 60mil deadenerKnuKonceptz & SkyHigh wire (complete setup) Link to comment Share on other sites More sharing options...

sully Posted March 30, 2013 Report Share Posted March 30, 2013 Your Yukon already has 3" stainless steel pipe, I would suggest the biggest Magnaflow 3" in 3" out muffler you can find and a set of Long tube headers. The muffler itself will not give you noticeable HP increase but the headers will. Also love the sound of long tubes on a LS motor. Cheap but good quality headers are available like the OBX with high flow cats (LINK). You may need rear O2 sensor extensions not to throw codes but you can buy spark plug anti fowlers at Autozone for less than $10 and drill them out to work instead of paying way too much for the same thing marketed as an O2 sensor extension. This setup would be about as much as a qauality cat back system and net you better gains and sound. 2003 Ford F-150 Reg Cab layin body on 26's 2003 Tahoe 3/5 drop on 26's with a 408cid Supercharged engine. 2011 Camaro 2SS 2005 VW GTI Stage II ECU, CAI, 3" turbo back exhaust, FMIC, lowered 2" on some plastidipped 18's 2003 Hayabusa lowered, stretched, cams, nitrous and custom paint Link to comment Share on other sites More sharing options...
djscrappydee Posted March 30, 2013 Author Report Share Posted March 30, 2013 Woooo them headers are salty. I like the idea tho man. I may run true dual's with magnaflows and turn down right before the back (2) PSI p2 18's Crescendo 2000 Audio Technix 0 gauge/ SHCA 0 gauge Pioneer AVH-P2400BT yellow top optima big 3 . xs batt.
