Quick question. I'm considering changing up my exhaust setup (one final time hopefully).

I have JBA long tubes, catless bpipes and an MBRP Pro Series 304ss catback. I was thinking of swapping out the muffler and tip in favor of a Borla XR-1 with a dumped tip over the axle for a cleaner look and a deeper tone.

My question: Is there any difference in sound/performance between the oval (40944) XR-1 and the round (40085) XR-1? Both are 304 stainless, and both are single 3-in/3-out. I was under the assumption that shorter mufflers will be louder. That being said, the oval is listed as 16" x 4.5"(narrow part of oval) x 7.88"(thick part of oval), and the round is listed as 15" x 5" diameter round.

Any thoughts on differences, or anyone with firsthand knowledge on either one? I don't anticipate space will be an issue, so no worries there.

why a dumped tip over the axle?

 

[TheHops]

Mainly to change up the look. I feel like the pipe hangs way low on my truck. It used to be tucked up nice and high behind my wheel, now it's probably an extra 3 inches to the rear, and is noticeably lower. That, and I'm always flinging mud on it and dinging it with rocks I'm sure. I think something is up with the rubber insulator, or maybe I need to just pull the whole systeml apart and reset it. I have this really annoying issue too from time to time that I haven't permanently fixed, where when the exhaust heats up and expands sometimes the rearmost hangar will rub against the anchor, creating this incredibly annoying metal-on-metal squeak at idle.

I may take some measurements and run it by a muffler shop and see what they think about trimming it up a bit and getting it welded in place of the clamps. It's probably just not clamped tight enough and is rotating/shifting.

 

[Pale Rider]

ahhh gotcha.

I was never a fan of the tail pipe cut short and left under the truck. exhaust gases find their way into a lot of places. especially with you having a cap or soft top...

funny how my tail/tip end has dropped more than 1/2 as well, but the rear hanger and rod are exactly where it was set before...

from what I`m told, the exhaust does move quite a bit.

You know, that is a very, very good point. I hadn't thought about that. I'd hate to have my truck running with me in the back and be breathing all of that in. Hmm.

That's interesting though. Most other Ts I see still have their pipe just below the body, so I thought I was the only oddball having issues.

If I do stick with the current setup, I've also been considering painting the tip with VHT (very high temp) black paint. I might plastidip it and see if I like it haha. :devil:

 

[Pale Rider]

Hops, I`ve tried them all, VHT, ceramic engine paint, (but not PD on the exhaust tip, lol) and they all look god for a limited amount of time. seems the VHT paint dulls in short order, the engine paint with ceramic good for 500° last a little while longer, but still dulls.

I don`t think it is a heat issue, as the tip doesn`t get that hot or to hot continuously, but the constant abrasion from road crap and the constant dooshing from rain off the tire maybe kills the painted finish.

maybe check out a black chrome tip to replace what you have...

yeah, my AFE tip does stick out more after the header and B pipe install and I`m sure it is bc it is relocated from the new parts.
I was unable to tweek or turn anything to make small adjustments bc the 360 degree band clamps have been on the AFE system since it was installed, and the pipes are set in deep. so it is what it is... for now...lol

 

[TheHops]

Killing my vibe man! Haha just kidding. I appreciate the info.

So when you say it dulls...does it just fade from glossy to matte? Or does it just end up looking like complete garbage? I wouldn't mind a fade-to-matte finish so much.

I went with the 40944 just because that's the part number I kept seeing everyone reference. After I cut my UQ off, mine is dumped just over the rear axle right before the spare tire. I love having the exhaust "hidden" after I did it. Looks much cleaner in my opinion. I never thought about the exhaust gases, but I don't think it's too much to worry about.

 

[TheHops]

Yeah, I only considered the exhaust gasses after he mentioned it because I sleep in my bed from time to time camping, sometimes with the engine running if need be. Probably not too good for the lungs in conjunction with a camper shell, if the gasses seep up through the bed.

How do you like the sound with that muffler and the dumped setup? Not loud enough/too loud/just right? Any bad resonance or drone in cab? Does it have a higher pitch, or a deeper tone?

 

[SouthernLion]

Ah, yeah I could see the sleeping in there with the engine running possibly being a little iffy.

I love the way it sounds now. I'm probably in the vast minority, but I wasn't a fan of the exhaust with the UQ. I missed the sound without it. Thus why I cut it off after about 5 days. It's definitely very loud, and there is for sure some drone when going down the highway/interstate. This is not my daily driver, so I probably have more tolerance for that kind of stuff than someone who drives it everyday. It has a deeper tone, and I feel like it got slightly deeper after it broke in a little.

 

[TheHops]

I ordered my UQ, but sent it back before I even put it on. I liked the sound of my current setup too much, drone/CIS and all so I just figured why take the chance. And it is my only (4 wheeled) vehicle, so that says a lot. It just sounds mean as hell. (On that note...my UpRev gets here TOMORROW!!! Can't wait to hear it after that!)

Well, I guess the clear solution is that I'm going to need to stalk you and stake out your vehicle until you start it up to drive somewhere, so I can listen and compare...

 

[OWP]

I would go with the 40944 but definately will want a UQ reso especially if ur gonna dump it, drone is pretty good on these mufflers without it, I sell borla black widow Gibson jba products and the two if needed, let me know if I can help u out

Your going to love your truck all over again once your tuned. I look forward to it for you lol

 

[GalaxyPro4X11]

I went with the 40944 so far without the ultraquiet. I'm running the Cajun set up with reso Bpipes an love he sound. Get a lot of compliments on it.
Only thing that really drives me a bit crazy is between 16-1850 rpm or right around the drone can get annoying. If that kinda thing doesn't bug you it's the way to go.

I'm a little bit too excited. If I wasn't working night shifts, I would be awake first thing in the morning sitting in front of my apartment door in a lawn chair, with a pen in hand ready for the signature. I swear if I don't see this package tomorrow, I will find this mailman... :ninja:

My major concern is my laptop, honestly. The battery is pretty much shot on it. When it's not plugged in, it only lasts 15-20 minutes. I hope that's at least enough juice to do a few runs at a time...because I really don't want to have to go buy a new computer, though if I have to I will lol.

Worse case maybe a small inverter would work.
But I'm sure that's enough time. Good luck man

yes, they start off losing the gloss, then even if a matte finish it will eventually turn light greyish, besides the bombardment of trash from the rear wheel...

you won`t know until you try it, I say go for it and experiment and see what you like... don`t forget to post pics...

Hops, you def don`t want to mess with the tuning, downloading, or data logging with a poor battery in the laptop.

during the downloads you can plug your laptop from a power chord from the house. Maybe you can squeek in a data log run before the battery craps out. The Titans electronics are ultra sensitive to voltage loss or spikes...
whatever you do, don`t ever lose the connectivity while you are downloading a Tune.

this is important to have a good running laptop, or reliable laptop when tuning the truck...
a good investment in a new laptop will come in handy for future tuning should you need it...

in the end, you won`t be able to wipe that sheet eatin grin off your mug! :big_grin:

The only way to kill the drone is with a UQ in the tailpipe but you have to remember the tailpipe must be vented outside the body or box to eliminate resonation back into the cab.
I tried about 20-30 different setups now and to eliminate drone with a 40944 it must exit.
Even with a UQ in a full tail if it does not exit outside the body line you will have drone.

Agree on the ultraquiet, just haven't wanted to lose any sound volume like I did on my nismo system with the ultra quiets. Definitely killed the drone though
