He Said I Could Do Away With It But I Read That If It Came With One It Was Illegal To Not Run It For Street Use.wanting To Get Bigger Pipes But Wanted To Be Sure Of This Issue Before I Do Max Power 06-21-2005, 04:10 PM You will probably throw a code without your Cat. Do a search for 'fingers stick' on this site. That will solve your problem. Illegal? I won't tell if you won't ;) TxChristopher 06-21-2005, 06:52 PM Ever do 70mph in a 60 zone? What were you saying about illegal? Seriously, I have yet to meet the smog police. You could run into trouble at inspection time if your state dyno's/sniffs but otherwise don't worry about it. bas4241 06-21-2005, 07:43 PM Newbie here, too. I'm thinking of ordering the MBRP 4"SS exhaust with the front pipe cat scratcher. Where do I look around here for a link to the Finger-Stick/EGR plate. I also just ordered the Edge/***. Learning daily! thanks.... dozerboy 06-21-2005, 08:07 PM They are made by the DP guys read in this thread or search LINK (http://dieselplace.com/forum/showthread.php?t=18029&page=11&highlight=finger+stick) Mark Craig 06-22-2005, 10:59 AM BILL THACKER, All the 2004.5+ have a cat, none of the 2001-2004 did unless it was a CA truck. Your truck will likely pop a SES light if you remove the cat, Fingers has the cure for that problme here at the site. You will probably be totally satisifed with a system like our MBRP cat back, gets you 90+% of the total spool up and EGT drop and still keeps the cat in place. Try it that way 1st, if you need more then get the finger and the front pipe from us. Our systems are built so the pipes bolt in with the 4 bolt flange so changing them is real easy vs a clamped joint etc. Mark @ DPPI | ||
