Is very hard to install yourself, took me and my dad 10 hrs with the right tools... You have to bend ur cab in like a bitch, but it was worth not spending 240 to get it installed and it sounds bitchin

 

sounds like ya had one hell of a time. im guessing u put a 4 inch down pipe on? glad ya finaly got it in even if it took 10 hours

 

Ya I did have one hell of a time... question for the DB Community, when I start up the truck after putting this new exhaust sound there is like a sucking sound for the first 45 sec of startup then it goes back to normal? is this bad? I know its not normal

 

Thats the EBPV closing. Exhaust Back Pressure Valve. Its good to hear that. It means its working.

 

Yep that is the EBPV, and for biged681985 the biggest DP you can fit in an OBS is a 3"

 

he said he had to beat the crap out of the firewall so i wasnt for sure.

 

Mine went in real ez. I bought the 4" aluminized MBRP kit. Yup 3" dp unless you want it in the cab. It took me 4 hrs and 8 beers. ( had to sober up for the test drive.)

 

4 hours and 8 beers? light weight

 

, Took me quite a while, and a good cigar at the end =)

 

i know its even utah beer.
