  1. I’ve had Texas Speed longtubes with cats on my 2015 Silverado for over year now and have no regrets. Good power gains and no drivability issues. I had to play around with my muffler set up to dial in the sound I was after. Currently running a single Borla oval Xr1 (40493) inline with a Borla Atak (400844) crate muffler. I absolutely love it. Nice and throaty when I want it to be and very quiet otherwise. Unless you run a big Magnaflow or stay with the stock cat back, it will be hard to quiet it down with a single muffler set up and longtubes. An extra muffler or resonator really seems to take the edge off on cold starts and when you get into it. You will feel some power gains. I wouldn’t expect more then 15-20 hp though. The gains with shorties will be hard to notice. Maybe a slight change in sound. It’s really not that much more work to install longtubes and a Y pipe. With the headers and Blackbear tune, the truck is much more enjoyable to drive over stock. Sent from my iPhone using Tapatalk
  2. Nice set up man. Would love to hear some sound clips. Im running a similar set up with a Borla Atak and oval Xr1 together. Sounds perfect with the TSP Longtubes. Sent from my iPhone using Tapatalk
  3. The Borla Atak will be the loudest option other then a muffler delete and it’s still won’t be super loud with the factory system. I have a Borla Atak crate muffler with Texas Speed Longtubes and it is loud. I ended up putting an oval Xr1 in front of it to tame it down. Sounds perfect now. Hard to beat that Borla sound. Flowmasters are a completely different design internally. The chambered mufflers will tend to drone at certain rpms. Sent from my iPhone using Tapatalk
  4. No kidding. Lots of guys run headers on these newer trucks and don’t have any of those problems. I’ve had my TSP headers on for over a year now with zero issues, definitely felt a power bump, and love they way the sound. Most of the headers now a days are very well built and seem to really wake these motors up. No comparison to some old mild steel Hedman headers on a sb 350. Sent from my iPhone using Tapatalk
  5. This member is using Kooks headers and Y on his 19 6.2 High Country. Tuning will be $$$ on the 19s and 20s. https://r.tapatalk.com/shareLink/topic?share_fid=33003&share_tid=234833&url=https%3A%2F%2Fwww%2Egm-trucks%2Ecom%2Fforums%2F&share_type=t&link_source=app Sent from my iPhone using Tapatalk
  6. Wrapped the b-pillars in flat black this past weekend. Very subtle with this color but its starting to grow on me. Sent from my iPhone using Tapatalk
  7. Just a few more of how shes lookin these days Sent from my iPhone using Tapatalk
  8. Once I was happy with the appearance, I figured it was time for a couple performance bolt ons. First up was some Texas Speed Longtube headers and catted Y I ran several muffler sets up with the headers including a Blackwidow Venom, Borla XR1, AFe resonator but ultimately found the Borla Atak 400844 crate muffler with a Dynomax Ultraflo 17267 resonator to sound the best. Nice and throaty but quiet if I keep my foot out of it and no drone. All 3” stainless mandrel bent tubing I know the catch can debate has been beaten to death but figured it can’t hurt with these DI motors so I installed a UPR Catch can Latest mod was an Airaid MIT intake tube with an AEM dryflow filter. I like the simplicity and the fact that it uses your factory air box. I also just had the truck tuned by Blackbear using their Autocal service . Truck runs so much better now. Future plans include Bilstein 6112 coilovers Texas Speed Stg-3 Cam Maybe 6.2 swap Sent from my iPhone using Tapatalk
  9. The new wheel bug started to kick in so after a lot of thought I narrowed it down to some 17x 8.5 Method Racing Double Standards 304s with their flush mount center cap mounted on some BFG KO2s 315/70/17. I originally ran these with just the 2” level and rear block removed but it rubbed pretty bad even with trimming. I knew I had to bring the front end up more if I wanted to run this set up so I put on a 3” Crown Suspension leveling kit with RC forged upper control arms. I also put on some Bilstein 5100 shocks and added the stock blocks back in the rear Sent from my iPhone using Tapatalk
  10. Figured I’d start a little progress thread of the truck. After being without a truck for about 8 months, I found this 2015 LTZ Z71 at my local Chevy dealer and purchased it in December of 2017. Truck was a clean one owner with 32000 miles. Only modifications were the Amp research steps, spray in bed liner, and tint. All mods except for alignments and tuning were done by myself. First mod Husky floor mats front and rear. A must with kids Within the first month, I had put a 2” leveling kit on, did some debadging and toning down the chrome. Blacked out the grill inserts, I replaced the chrome mirror caps, and swapped the door handles out for a colormatched set. I’m just not a fan of big wheels so I replaced the stock 20s for some stock 18s with plans of running a bigger tire eventually. These tires looked so tiny. Picked up some Falken Wildpeaks AT3W 275/70/18s. I was happy with this look for a little while but knew I’d eventually want to throw some Method Race wheels on like my last 2 trucks. Also replaced the chrome window trim to get rid of the last bit of chrome excess. Sent from my iPhone using Tapatalk
  11. I thought I would give a review on my recent experience with Blackbear using their Autocal service. First off, my truck is 2015 Z71 Crewcab with the 5.3, 3.42 gear, leveled on some BFG KO2s 315/70/17s. About a year ago I installed some Texas Speed longtubes headers with catted Y and had a shop in Tulsa “dynotune” the truck to get everything right for headers. I won’t mention the tuners name because this not about bashing him. The tuner did basically what I asked of him such as adjust the fuel trims and spark for the headers, correct my speedo for my tire size and change up few things with the transmission. Overall the tune seemed to work just fine. There were little things right out the gate I didn’t care for. Mainly to do with the transmission behavior. At times the shifts were firm, almost harsh and other times lazy and unpredictable. It also had some torque converter flair mainly in 3rd gear and a hesitation on hard down shifts to pass. I had asked the tuner earlier this year if he would have the time to dial these things in for me. He gave me the impression that he really didn’t have the time to mess with it. I decided screw it, I’ll have Blackbear tune it. I’ve known about Blackbear for a long time. I would say 99% all good. I’ve heard some guys ****** about their communication but most of that I can only assume is because of their workload at that time. I purchased the Autocal and it was shipped to me within 3 days. The overall process is fairly straight forward. Just take your time and read the Autocal directions very carefully. They have done an excellent job walking you thru the entire process. Everything you need to know is there. Just read. I emailed BB a list of my mods, my concerns with the current tune, desired outcomes for the new tune along with my driving data log and current ECM/TCM tunes. I got a response within a couple hours that I had been added to the to do list. 1 week later Justin emailed my new tunes. I received a 91+tune, an 87-89 tune, a modded TCM tune along with the stock ECM/TCM tunes. Now to the tune itself. I loaded the 91+ octane and modded TCM tune in the truck. Of course living in Oklahoma, I literally got a tornado warning just as the tunes finished installing. Needless to say I didn’t get to drive the truck that night. So the next morning I hopped in it and drove about 10-15 minutes. Right away, the truck felt very different. It’s like Justin knew exactly how I wanted to drive the truck. It feels much lighter and nimble coming off the line. Shifts are quick, firm, predictable and the RPMs stay up in the power. No more hesitation on hard accel. Throttle response is immediate and it pulls much harder up top then it did before. It actually surprised me the first time I hammered it doing about 35-40. I have always wanted to do a 6.2 swap in this truck but honestly now it feels plenty quick with this new tune even on nearly a 35” tire. I’ve emailed BB a couple of very minor things I’d like to have changed but the more I drive the truck, the more I just want to leave it exactly as it is. I realize he’s tuned a ton of trucks over the years but still I’m very impressed on how with just a little information, Justin can get it dialed in the very first time. I am very happy I finally went with Blackbear. I should of done this a long time ago. The up front cost may seem like a lot but honestly, it’s worth it. He’s right there with most tuners on price and he’ll update the tune for free for any future mods. Some exceptions apply I’m sure. Another happy customer here. Hopefully the truck is happy. I’ve sent them a follow up data log to confirm. Thanks for reading. Sent from my iPhone using Tapatalk
  12. That looks so good man. Are you planning on keeping the steps? Sent from my iPhone using Tapatalk
  13. No drone but you can definitely hear the exhaust at higher rpms. I also have AFM turned off which is notorious for causing a drone or helicopter chop sound with aftermarket systems. I’m running the Borla muffler flipped from what they recommend. Running it the other way seems to give it sort of trumpet effect and cackle with the longtubes. The Dynomax resonator also helps tone it down some. Sent from my iPhone using Tapatalk
  14. Held up great so far. I’ve got around 15k miles on them. Still lots of tread and just as quiet when I put them on. I don’t tow with this truck so I don’t know how a C rated tire would do. I run around 40 psi in them seems to be the sweet spot. My wife’s have barely 1000 miles on them. Sent from my iPhone using Tapatalk
