I noticed you didn’t change your exhaust gaskets, is there a reason for that?

[@justkillnbugz]

Thanks for the question. Yes, the SPC pipes did not require a gasket. Ride safe.

[@MotoBlonde]

Awesome to see another SPC! Super happy with ours!!

I just got mine yesterday. I learned about this exhaust watching Moto Blonde and decided to pull the trigger after watching your channel. I love it but did you notice there’s a spot that it’s a little bit too close to the motor? It might just be me but I’d love to hear your thoughts.

[@justkillnbugz]

Thanks Cris, I appreciate the comments. My first video on SPC I mention motoblonde as well since my conversations with her turned me on to them as well. I am glad you got them, they are great people and have a great product. I did notice the same thing, and have been watching it, but have not had any issues yet. I do know that if I do, I can reach back out to SPC and they will do their best to help with any problems. Enjoy the pipes and ride safe.

[@crisvaldez1447]

@@justkillnbugz Glad to know I’m not the only one to notice that issue. You think I should let Greg know about it too? I really value your input that’s why I ask. I’m really enjoying mine and I’m glad I waited. I’ve had my bike for almost 2 years already and I almost pulled the trigger on the TBR. By the way, have you put in a tuner already. Thanks again for the videos!

[@JakobKaizen]

How loud would you say that the big bore is compared to let’s say stealth pipes turnout, hpi short and tbr turnout?

[@justkillnbugz]

Thanks for the question. I don't have experience with those pipes, but I can tell you that compared to my Rineharts they sound just as good but a lil bit louder. The Big bore Pipe sounds awesome. It had a crisp deep sound at low RPM and unleashes at higher revs. Checkout some of my other LRST videos and you can hear it while riding. Not much help I know but I can only speak to what I have used.

[@SonOfRich56]

Great video and the pipe looks great as well. Would you say it’s a neighbor friendly exhaust? I like a good sounding exhaust, but don’t want to be THAT guy.

[@justkillnbugz]

Thanks for the comments and the question, much appreciated. I would say it is neighbor friendly, none of mine have complained and it sounds nice and deep on start up. Many actually like the sound and have complimented me on it. The real tone comes in when you get on it as the video shows. I also did a new video on my 2023 RG CVO with the new long pipe version from SPC and you can see the sounds there as well. Same tone and deepness, but not obnoxious for either 🙂. Hope that helps and ride safe.

[@SonOfRich56]

@@justkillnbugz thank you! Also have you noticed a difference in HP or torque?

[@justkillnbugz]

@@SonOfRich56 You bet, glad to help. As for the HP and Torque, it still has a stock map and no tune. Can't put one on yet in CA, but it does feel a bit more snappy, but I don't have numbers from stock to compare. Besides, great sound ALWAYS makes it run better...LOL

[@bradnugent58]

No new gaskets?

[@justkillnbugz]

Nope.

[@88jjdecay]

Doing the install right now for the same exhaust. My header bolts are 13mm….

[@justkillnbugz]

Awesome! Glad you got them and are getting them on. Nothing like consistency on bolt sizes for made in USA (mm) products right? Lol. Your gonna love the sound!

[@FXFBS23]

Robert, thanks for making this SPC vid. Sounds great with stock engine! I’m considering it for my stock ‘23 Fat Bob. Not sure if I should do a screamin eagle stage 2 while I am at the dealer along with the SPC. Still under warranty so I was opting for the SE stage 2 and then, if desired, switch cams when warranty ends. I’m concerned it will be TOO loud with stage 2

[@justkillnbugz]

Thanks for the feedback! I am glad you found it useful. As to the sound, these are great because they are mellow when low rpm, louder than stock of course, but sound amazing when you hit the mid band. As for the stages, not sure where your located, but here in CA if I put a tuner on the bike it voids my warranty. Check with your local dealer to see where the limits are and what would be covered and not. Obviously cam and exhaust would not be if changed but good to know where you stand with the mods you are considering. Thanks again and ride safe.

[@jjpro20021]

@@justkillnbugzI’m about to put this exact exhaust on my low rider st do I need to put a tuner on it ? I’m asking because I don’t want to void my warranty aswell. Will it mess up my bike if I leave it without a tune?

[@justkillnbugz]

I did the same with no tune and have had no issues in my 2022. Enjoy and ride safe.

[@FXFBS23]

Update: I love my SPC. I ended up adding g these along with a SE stage 2 torque cam and SE tune. You can def feel this (conservative) SE torque improvement. The HD dealer did all work and I did not void my warranty. This coming winter I plan to go to a more powerful cam, upgrade the oil pump, manifold, etc and get a diff tune. But at this point in my ownership I don’t mind voiding

[@jjpro20021]

@@FXFBS23 are you in California? Because I am putting on the same pipe and I don’t want to avoid my warranty either so if I take it into the dealer with that pipe already on it, they won’t say anything?

Question which way is your bag bracket installed it seems my bag really struggles latching any help or pictures of which way you installed yours would be much appreciated

[@justkillnbugz]

Sure. Shoot me a message on my instagram account with a pic of what you need shown and I should be able to help out. In short though, I put the bolt for the bracket in the lowest aft hole, kept it loose, mounted the bag then tightened it where it fit. Hope that helps.

[@ryansweet9104]

I thought the exact same thing when I installed mine. The bag seems to fit 'tight' and struggles going on. I may flip the bag bracket and see if that helps.

[@justkillnbugz]

@@ryansweet9104 Thanks for the comment. It could be that, check my video on which way the bracket is facing, may help. Also, when I did mine, I put it on loosely, mounted the bag, then tightened it once the bag was on to help align it a bit better. Hope that helps and ride safe!

[@depererat35]

What are the torque specs did you use new gaskets

[@justkillnbugz]

Thanks for the question. Torque values were not indicated by the manufacturer. I used loctite and tightened them until they were securely in place. Ride safe.

[@kristopheryates7595]

Great videos. Good detail describing exactly what you’re doing to cut our work time down. Thank you. I’m installing my SPC big bore pipe now. Having a little trouble figuring out the bag bracket. How did you mount your spc bag bracket (not the pipe bracket) and what bolt did you use?

[@justkillnbugz]

Thank you. Much appreciated. I used the same bold from the lowest back frame that attaches the swing arm and mounted loosely. Then I put the bag on and positioned it, then tightened it. Then took the bag back off and continued. Hope that helps, you will love it.

[@kristopheryates7595]

[@bcbsilverhawk8426]

Nice video. Pipes look OK. Would prefer them to go farther back. A bit too short. Take care.

[@justkillnbugz]

@@bcbsilverhawk8426 thank you, appreciate the feedback. I have seen a few different 2 to 1 designs like this version that do go a little further back like the Bassani pipes. These run great and sound awesome and I am seeing more and more bikes with them. Vance & Hines and a few others do have a straight pipe solution that can go all the way back as well. I just think this design is supposed to be a shorter length which is where the personal preference part comes in for the look people are trying to achieve. Thanks again for the awesome feedback and comments, ride safe.

[@jasonharrold6686]

How do the hp/ torque numbers compare to Bassani/ thrassin or HPInc

[@justkillnbugz]

Great question, thanks. I do not know as I have not had it dyno'd yet. It has been in the shop as other videos discussed for a lovely oil leak issue, but once I have them I will post the numbers. You can check on the SPC site, they may have some additional details on specs there. Ride safe

[@jasonharrold6686]

@@justkillnbugz would yoy recommend them despite the oil leak?

[@justkillnbugz]

@@jasonharrold6686 If you mean SPC pipes? Absolutely, the pipes had nothing tondi with the leak. It was a Harley thing that a few others have commented on in my video comments for the leak. If you mean the low rider? Yes, it’s a great bike and a lot of fun for mid control lovers, of which I am not, but that was easily fixed as well. Lol. Ride safe and thanks for the support.

[@Bigiron429]

HPI is an overpriced pipe that has around the same numbers as a Tbr/DND Pipes l. Sawicki speed and thrashing by are probably the best comparing the cost to a HPI pipe

[@G.crickon]

Did the bike require a tune or flash after the pipe was installed?

[@justkillnbugz]

Thanks for the question. It is recommended that you have the bike dyno tested and tuned for any new full exhaust system (not slip-ons) to ensure peak performance and operation. Due to the oil filter issues I have been experiencing (posted in other videos) I have not had a chance to do a dyno test yet. In CA, the EPA has not approved tuners to be installed on certain 2021/22 models yet due to updated emission controls. Also in CA, if you add a non approved tuner to the bike, it will void and block your warranty for any issues that could be related to service in those areas. For me, the bike seems to run great with no popping or backfire noises (once in a great while depending on aggressiveness) as is. So I will wait until we have a warranty approved solution for my state, or when my warranty expires. Best to check with your local dealer to see what the rules and guidelines are where you live. Thanks again and ride safe
