Shit! Sorry man. Totally spaced on this over the weekend. Here’s a clip from just now. Trucks been sitting for about 2 hours after my drive home. Does this qualify as a cold start? Lol

Sounds really good. I just don’t want to spend 1200$ and have it be too quiet so I just wondering how it sounds while driving or if it’s barely noticeable

This thread really took off without me checking on it much.  I ended up going with the Flowmaster FlowFx.  Didn't break the bank and sounds pretty good.  Slight drone on the highway but nothing the ti

Wish I could help ya but it’s hard to describe in the cab. The corsa video on YouTube is spot on if you ask me. I’ve had Borla before and I feel like the Borla was more noticeable in the cab, but not by much. 

 

I debated for nearly three weeks on which system. Finally got annoyed with myself and took a chance on Corsa. Super glad I did. I honestly think you cant go wrong with either option.

Running a Flowmaster 40 series at the moment, not much louder than stock at idle and normal driving. Noticeable difference when wide open. Possibly taking the resonator baffles out next. 

Cover up the mesh screens on the dual exhaust pipes.

Here's another muffler delete

 

So to achieve this sound you need to delete 2 thing (muffler and 6 screen on piping by spare tire)?

Basically. Looks like this guy wrapped his 6 resonator screens in exhaust tape. You can also cover them with sheet metal and clamps, though.

These are some of the highest selling vehicles on the planet, I can't believe there isn't a good hi-po replacement muffler for them other than a $350 muffler!!!!

Do any exhaust mods void your warranty?

It used to just on the exhaust, who knows these days. Of course you can still get one from the factory. Louder exhaust that is.

Yeah he states in the video - muffler delete and blind those screens. I would cut them out instead of blinding them honestly.

Definitely not, if you can easily remove them before service... :)

Why not just go to the muffler shop and have a permanent, more quality job done for $40 ?

1. You have some different shop options than most of us, I think. $40 is a pipe dream.

2. $40 is more than $20

3. I like that I can take my mod off whenever I want, and then put it back on whenever I want. 

4. No one is crawling under my truck to gaze at the beauty of my exhaust system, so who cares if there are a few clamps on the pipes.

Yeah fair enough. Especially point #2 lol.

 

I kind of shrugged it off before I read the entire topic. I'm going to try covering the screens, seeing as I have the materials. I'm unsure on the flapper valve.

Opening the flapper is where the real "Oomph" comes in. :cool:

I'll see :sigh:

 

to my defense, I had a black widow exhaust installed at a local shop for $45, that was removing the old, and flapper valve, and a few new mounts (smaller than stock).

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
