Holes in exhaust

[notlimah]

Well, was crawling around under the truck installing my Timbren's noticed two holes in the exhaust. Maybe a BB size hole in a couple of the welded seams. Is this something I should change out sooner then later? Or would I be good waiting until I get around to it?

Have access to a welder?  If so, I'd just fill those holes quick and forget about it.  Otherwise, you can get Tiger Tape from an auto parts store.  It's exhaust tape that hardens (almost steel-like when done) and stops leaks.

Nice, I'll look into that. No access to a welder so I'll check out tiger tape.

 

I'd love to use this an excuse to get a new exhaust but I can't throw anymore money at the truck for a bit haha

[trreed]

Oh come on.  Your wheels were a lot cheaper than mine, and I still have to buy tires lol.  5" time.

[notlimah]

5" is gonna be too loud! Although that's what I really want. I would just rather it be quiet enough to when I'm pulling a camper with the fam, we can actually have a conversation lol! I was planning on a 4in with resonator.

[trreed]

Do it!!!!!  So my current setup is a 4" magnaflow with muffler (courtesy of @TFaoro) and the thing that quieted it down the most was a 14cm non gated housing.  At idle, I can only hear the turbine of the turbo, and I have to be standing at the bed to hear the actual exhaust note.  Compounds also quiets the truck down a lot as well.....  Food for thought, since you have that new trans...

I like my 5" with straight through mufler, but to patch yours up use something like thathttps://www.walmart.com/ip/Proflex-Shielded-Coupling-3-In.-No-Hub-Cast-Iron-To-3-In.-Copper-110621/152213470?wmlspartner=wlpa&selectedSellerId=1122&adid=22222222228048179231&wmlspartner=wmtlabs&wl0=&wl1=g&wl2=m&wl3=146917152386&wl4=pla-261094429132&wl5=9018656&wl6=&wl7=&wl8=&wl9=pla&wl10=101593696&wl11=online&wl12=152213470&wl13=&veh=sem

They come in different sizes and just spread some hi temp RTV inside before clamping it on. I wouldn't weld it you'll keep burning through,  brazing might work

Dont you put that compound evil on me! Hahah 

 

For now my plans are to upgrade to a 62/65/12 when the time comes. Not going to entertain twins until much further down the road. 

 

5in from what I've heard is just loud, no getting around, except for twins as you mentioned. I'm not a big fan of exhausts muffled so I'd like to stick with 4in with a resonator, I think that'd be a good compromise.

 

Also, here's what I'm working with so sorta limited.

That's going to crack all the way around aventualy, had that happen. I'd say mufler tape or cut it out and replace a pice. There is a little bit of room to put that clamp from fernco on, and usually they are ss.

5" on both my trucks and they are very quiet.....

[CTcummins24V]

I'm running a 5" with a muffler and FTE resonator to keep drone down. I would guess my old 4" was louder, 5" is just deeper sounding.

With twins or single? What brand?

I remember the video you posted, it definitely sounds quiet! How loud is it with just the resonator?

[jlbayes]

Singles at different times. One with a single now and the other with compounds.

[notlimah]

So it was actually quiet with a single hunh? What brand exhaust were you using?

[jlbayes]

Yes it had a very nice sound to it. Diamondeye is on the 12v. 24v is homemade leftovers now lol

[TFaoro]

4" with a single turbo and a muffler was nice in the cab but pretty loud outside.

4" with a single turbo straight pipe droned pretty bad in the cab.

4" with compounds and straight pipe was nice in the cab and fairly quiet outside.

5" with compounds and straight pipe drones a bit in the cab. I'll be getting a resonator for it.

Were these straight piped?

Nice, what brand were you running?

 

I've been eyeing MBRP just because the exhaust angle exit looks the easiest to eliminate or cut down on drone.

[trreed]

I can answer that question!  His (now my) 4" is a magnaflow setup.  His 5" is diamond eye.

Word

 

Can the 5in fit a 285/70/17 spare?

[trreed]

That'll be very tight if you can make it fit.  That tire of yours is 32.71" diameter.

I currently have the stock 265/75/16 spare and the 4" exhaust is about 3/4" away from it.  That tire is 31.65" diameter.

So you're growing 1/2" in tire radius and 1/2" in exhaust radius, so they'd be touching... Unless you rigged up a heat shield or (god forbid) bash the tailpipe in to clear the tire
