Rocket exhaust??

Not sure how they are now. I know the leib family owned it before and pretty sure they sold the company. 
 

also depends on what bike you’re putting it on. Ask jS7 you need a factory ecu. 

Check out the ignitions from twisted first then start to look at exhausts. For the price besides the “bling factor” exhausts aren’t usually worth it. 

They still do good work with the new owners. If you call them to order the exhaust like I do you can tell them how your building the bike and they can make you a pipe to suit your needs. They offer different can lengths and can do the same for headers or you can buy their full exhaust that's pre made for the bike like everyone else. Their packing material they use is the best around. It's made by Bristol and it comes in pillows packs. You just wrap the core and drop it back in. I have one on my race bike and have a few people that run them as well on bikes I help maintain. No one has any complaints and they worked on the dyno as expected.

Give them a call. 

They gave me excellent customer service, the mufer i bought seems well made. Recovering from knee surgery so i have to wait a few months to try it out. Definitely lighter as well.

Yep I one when it was Don Lieb as the owner. It was excellent quality, they can tailor the exhaust to help place the power where you want it. Honestly, it was a great choice especially if you don’t want full TI

I purchased one for my 19 kx 450 and it rubbed the shock so be careful with fit. 

Great Product, Good crew with good customer service.  I really liked mine.  It fit very well which is where I see most exhausts fail. 

Highly Recommend. 

I bought one for a 2007 Honda 250R build I'm doing. I bought when Lieb owned the place, requested a resonance chamber and received it without it.  Not a huge deal, but the customer service wasn't that great with him. The new owners seem pretty good, they added the resonance chamber for like $75 and were easy to get in touch with.  I tried ordering another exhaust system for the same bike from them because I'm building two of the same bikes, but unfortunately they said they couldn't make them for that year anymore.  The exhaust does look great and fitment seems really good.

Ignore the down votes, I thought they look pretty good as well.  I haven't been able to use mine yet, I have DRD as well. I working through total knee replacement from 2022 and probably getting shoulder surgery in the next few months.  Fitment and looks are great in my opinion.  

Damn I was going to purchase that had it in  my cart came back a short tme later and it was taken.

Oh well enjoy it

You might try emailing them, hard to believe they are out of 2023's already. Maybe they can build special orders.
