BigCountry Posted February 21, 2009 Author Report Share Posted February 21, 2009 If you've got a 5.3 or 4.8, they yes, they would bolt right up. Guys with a 6.0 can also choose to run the exhaust off of a 5.3 truck. Quote Link to comment Share on other sites More sharing options...
96vteccd5 Posted February 22, 2009 Report Share Posted February 22, 2009 Yea man let me know how are the install is. I want to install some on my 5.3 but I would have my exhaust guy weld on some high flow cats. These fit my pockets very well and if they yield good gains on the dyno, they will be purchase. Keep us informed and good luck. Quote Link to comment Share on other sites More sharing options...
2bfast Posted February 22, 2009 Report Share Posted February 22, 2009 Looks good. I didnt have any problems with my OBX's other than one of the tubes on the drivers side hitting the heat shield on the firewall Took the heatshield off and took a hammer and sandbag and hammered it in to clear the tube and reinstalled.

BigCountry Posted February 26, 2009 Author Report Share Posted February 26, 2009 (edited) getting closer, got a little more tweaking to do on the part that I modified... Should pick it up this evening, I'll post pics of my whole setup soon, but I've got both my girls for the weekend, guess they still won't be on, but next week or bust!

BigCountry Posted February 28, 2009 Author Report Share Posted February 28, 2009 And I hope this Muffler isn't too restrictive Yes it's overkill and not ideal for my nearly stock setup, but this is just phase 1 Quote Link to comment Share on other sites More sharing options...
delay18 Posted February 28, 2009 Report Share Posted February 28, 2009 Did you get everything from the Y back custom bent or did you just by a made set up? Quote Link to comment Share on other sites More sharing options...
