Street Pro (a The Diesel Place.com sponsor) needs your help –We have been asked by many customers to provide inexpensive and easy to use “couplers” or “adaptors” to facilitate the use of our 4” Power Master cutout into GM / Duramax environments without the aid of exhaust shops or welding by the consumer. See the attached photos to understand the "welding" we are refering to. (OK --I know it's a Dodge but the pictuers just came in from Denver last night and it is a very clean job) This will be a part that will allow installation of the cutout by means of “band clamps” . The part will fit over our 4” OD cutout and over the existing GM / Duramax exhaust pipe aft of the down pipe and forward of the muffler and / or cat. The question is: EXACTALY what is the outside diameter of a Duramax powered GM stock exhaust pipe in that location and did the size of this pipe change over the last 2 years? If it’s 4” today, we can provide a 4 to 4 coupler – if it was 3.5” in 2000, we can provide a 4 to 3.5 --- you get the idea – we just need to know what the “standard “ pipe size has been over the past few years --- And before you ask, <B style="mso-bidi-font-weight: normal">NO[/B] we don’t have a 5’ cutout –not yet anyway!http://dieselplace.com/forum/smileys/Confused.gif THANKS FOR YOUR HELP !

Thanks! -- That is the anwser we keep geting on other sites -- we just want to provide the sizes ya'll need !http://www.dieselplace.com/forum/smileys/Big Smile.gif


And we say --- IF You Got It --SMOKE IT !

It is 3.5". I know I just recently cut mine out.. Straight pipe, same concept as what you are selling but just less expensive..http://www.dieselplace.com/forum/smileys/Approve.gif

But does your straight pipe have a "mute" buttonhttp://www.dieselplace.com/forum/smileys/HiHi.gif

Thanks BONE DOC --- That confirms the anwser --- 3.5 it is! By the way -- Love your statement at the end fo your post -------- "People too weak to follow their own dreams, will always find a way to discourage others"..... That Sir, is the TRUTH !


Fingers -- http://www.dieselplace.com/forum/smileys/Clown.gifthanks for noteing the "be quite, the cops are behind us" button! -- that same button can also be usefull when pulling into your driveway when you are getting home 4 hours too late on Friday night!


Thanks --Ya'll have been a great help!
