Full off-road exhaust for my Maverick Tremor prerunner build

[thev8man]

I wasn’t gonna say more but I feel like I may be the one guy he really shouldn’t think uses his maverick for off roading on a dirt road.





Not to mention he must not see my posts on hauling.
Too bad he put me on ignore so he doesn’t have to actually admit he was wrong while trying to be a turd.

My upgrade

What tune are you going with?

I have a livernois , my cal , with 4 tunes : towing performance, 87 performance, 91 performance , e30 performance ( mix of e85 and 91 fuels).
Generally use 91 performance unless , going on long trips , switch to 87 performance then .
Way better shift points and gear holding it seems.but peppiness on 91 is great , will do front wheel peels arond corners on the street with the 32” mud terrains.

Sounds good. I’ll have to pick your brain later about the livernois.

My upgrade

All stock exhaust pipe pieces, I just had to add a universal hanger and more a hanger.

I've always been a fan of the side exit exhaust on v8s. Had a nice Gibson system on my 1998 Silverado Z71. That thing had some crazy loud exhaust notes for a truck.

I'm not quite sure I'd be a fan of it on a four-cylinder though. The look yes, the sound not so much.

Keep the stock muffler.

Stock intake or ?

I figured I’d post some pics of my off-road exhaust for the prerunner build .
I got the Fast Mavericks downpipe and extension pipe along with antifouler.I had purchased an AFE side exit cat back kit about 6 months ago and waited for their run of kits to come in .
And finally got around to spending a day to do it.
Luckily I have a spacer/ drop kit on my front subframe making room at the back of the engine a lot easier.

the clearance clarance is a lot better now , no low hanging fruit out back !
Spool up is quicker and obviously more pronounced.
Overall install was slow and steady,I did tig weld the cat back and reducer I added .the downpipe and extension was 3” and cat back kit is 2 1/2”( all that’s offered right now.)I may go 3” to bullet muffler with side output oval or nascar style side dump from downpipe later we will see . Time is always an issue.
Anyways with new tuner going on this week should see some good gains , may take to 1/8mile track on Friday ,see what it does on 32’s
The quality of the Fast mavericks pipes - top notch , along with quality band clamp, with notched band rings ,quality flex joint and thick pipes.The afe kit is good fitting , a little thinner on material and obviously production welds.
Sound is strong with no cats and side exit with just a small straight through muffler.
Drone is not bad under 75 mph , but it does get a little loud at full send when moving out but to be expected .
Once I finish the stereo I’m adding this week , can always keep that volume up!
Two fasteners will be the majority of your time taking stock stuff off!
The block hugging stock downpipe nut ( 15mm) a real pain to get to , best is to take intake pipe off.

And insert a deep 15mm with a universal on a 10” extension from drivers side to behind the cold side intake tube and ratchet from above next to battery.
The other one is the factory hot cat has a support bracket with a 21 mm nut that takes forever to get off!
One click at a time!
But all aside it came out good , my skid plates from jcr are coming in soon and should provide a smooth strong bottom for trail dragging .
I will be doing a complex stadium style truck rear bumper to wrap under to center diff to mount a stout skid plate then.
Will post later

Honestly the best looking Tremor on here ... which is saying a lot, bc I f*ckin LOVE mine! haha You're killing it dude. Keep up the great work, and thanks for letting us follow along with your build.

Did you do any flex tunes?
I have the 87-93 tow
87-93 performance
93 performance
And e30

Yes just drop in k&n filter.
a decade off road racing with just drop ins compared to running custom ,proved to us the factory boxes keep a really good amount of silt and sand granules from even reaching the filter side.
plus we would swap on heavy silt bed races multiple times a race . Full custom works great if you route intake into The cab area , but on our stock class vehicles it wasn’t a viable option, and on a street truck it is excessively loud in the cab . If it goes full prerunner/ off road only may do it then.at that point we usually where comm headsets because of bypass clicking noise ,engine noise and heim joint noise.

That’s all I did
but they are rated at 91 as that’s all we get on the left coast.
full flex fuel(e85) won’t work on mavericks as the fuel pump,and injectors need to be upsized ( not enough volume), mainly I believe the injectors. At that point it would be all custom tunes to back the pulse width down enough for regular gas then .
