Sold the old crusty 22s. That put $1k towards the cam swap. Back to OEM 20s. It drives and feels much better with 20s to be honest. I still want another set of 22s though... 

 

At this point it is no longer my daily driver. I got a Chevy Volt because I'm driving a lot for work and it saves me money. So the truck gets to stay super clean and detailed 24/7 and stays inside. I take it out any chance I get when it's not rainy. So much easier to keep it clean that way.. any time I take it out it looks like it just came off the showroom floor.

***side note: My wife didn’t realize her old wheels were on my truck until I told her a month later...??‍♂️ I wonder if I could turbo or supercharge the Yukon without her noticing!? Haha

I could pull that off if I had the cash.[emoji16] My wife isn't that observant. Sent from my Pixel 3 using Tapatalk

Whats the part number on your Xr1? Got any more sound clips?

Part number 40575

1 7/8 long tubes to X and dual 3” pipes  with two Borla 40575 dumped before the axle.

 

Here’s one that I think was a cold start if I remember correctly. I’ll get another driving one uploaded soon too.

Sounds great I just ordered the 400372 multicore which is a 17” oval case, I believe yours are 21”. Hope it’s not too loud with my TSP headers😬. Sounds like these get pretty rowdy on some throttle. Any drone with these?
 

Currently running a 19” Borla ProXs. It sounds pretty good but looking for just a little bit more rasp.

Yes there is a bit of drone, mostly around 2K rpm depending on load, but it’s enjoyable for me, not bad at all. My wife doesn’t like it though. But she drives a Tesla so.. 👍

 

I personally hate too much rasp and it seems like with my setup I’m constantly feathering the throttle to reduce it. Unless It’s WOT — it screams like a drag car then, and it’s all worth it. Haha

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
