Spintech Exhaust?


Recommended Posts

Posted

I have Spintech on my 2001 GMC 8.1/Allison.

I have two 3 in and two 3 out. Sounds good just

a little loud for me when towing 9000lb camper up hills. :D

I was told by my dealer that as long as you do not mess with

the cats that is dosen't effect the warrenty. :confused:

So does that mean that the link I provided in my first post that the guy has an exhaust that voids his warranty? On his page it says that he has a catback exhaust. It sounds pretty sweet though. Do you get the same kind of sound without modifying the cat?

I haven't heard of any warrenty being hurt by exhaust work.

I guess it would be up to the dealer!!

The term "catback exhaust" does not mean that he modified/replaced his catalytic converters. In actuality it means almost the exact opposite. Everything back from the catalytic converters (muffler, pipes & tips) was replaced. In other words, the only stock exhaust is the cats.

 

The advantage is that cat back systems normally come with mandrel bent pipe (keeps a true diameter even when the pipe turns), and it is usually more costly. Many peeps will buy standalone mufflers and have their own muffler shop run the pipe, which is usually cheaper. The biggest drawback is MOST muffler shops don't mandrel bend pipe, and when they do it cost big $$.

 

In regards to an aftermarket system affecting the warranty, many exhaust specialists (Borla, Corsa, etc) are posting verbiage on their websites explaining it is NOT legal for a dealer to void your warranty. Here is a cut copy of Borla's site:

 

Q. Will it void my factory warranty?

 

A. No, some cars even have BORLA systems as the OEM exhaust. All of our street exhaust products are 50-state emissions legal. Our headers are 50-state legal and C.A.R.B. approved. In fact, it is illegal for a dealer to deny you the OE warranty because you have changed the exhaust system. For more details, contact SEMA, the trade organization of the automotive aftermarket which has been instrumental in protecting such consumer rights, at www.sema.org, and they can refer you to the Magnuson-Moss Warranty Act of 1975.

 

Here is the direct link to where I found the above blurb:

Hope it helps! :cheers:

 

PS - By the way, that site you provided with the grey truck is cool. That truck rocks the house!! Thanks for sharing. :sleep:

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
