That why if you buy Ti you don't get a resonated one to avoid that problem
BTW- Despite the fact that Ti will not last a lifetime, doesn't mean it won't last a very long time. You will most likely sell the S long before the exhaust fails.

Ti is a brittle metal. A lot of times what happens in the resonator or exhaust is a piece breaks off and rattles within the resonator. Many Ti exhausts are constructed (or have been in the past) with a cheap interior packaging (sound deadening scruffle) that also rattles lose and causes problems. To break open an exhaust you are going to need to find a shop who can weld Ti as it is different from welding SS exhausts.
I would not bother spending more than 1500 on a Ti exhaust, because the probability that it will break is more than likely and those pretty JDM welds are going to be grinded off to fix your pipe. Ti is a great lightweight metal, not sure how durable it is.
Make sure you hear the exhaust before you purchase, if the car is not a dedicated track monster you are going to want to maintain a resonated muffler design. Anything over 110db is going to be uncomfortable, and not practical on a daily driver. The tracysport 80mm on a NA car is going to be ridiculously loud, 70mm on a NA build seems to be the norm. I would stick with the 70RS, its a resonated single, constructed of Ti, and has a unique tip design. The quality may not be up to par with the Amuse or tracysport, but hell... its going under your car, not on your mantle.
On the flip side if you can get a warranty (not likely) from Bulletproof, and they will honor any interior damage that might happen in the near future (5 years) then go for it.
If you get an outstanding warranty and can afford the exhaust, go for it.
But Ti exhausts, IMO, just aren't worth it for a DD. They were meant for race use, where it sees little use (ie. not daily driven) and where the weight savings count the most.
Ti for a daily driver: you don't need the weight savings, the initial cost is extremely high, and the cost for any type of repair is also high. The material is also usually pretty thin, so it's brittle. I've seen pebbles pierce the skin of Ti exhausts used on street cars.
SS exhausts are much more practical for street cars.
We have yet to have ANY issues with the current generation J's Racing titanium exhausts. The Amuse have had an exceptional track record as well.
Usual wait time for amuse exhaust is 60-80 days here... IF its not in stock here, which lately it is here. We stock most all of the amuse exhausts and aero parts.
I'll have picks up as soon as it does! I was pretty hesitant about spending that much $ but I know I'll be very happy w/ it. I hope my wife is as happy as I am when she finds out I bought it.
I took it to Burns Stainless's ti welder - chris at BPR
all Chris does all day is weld custom race ti exhaust manifolds..
He had some interesting things to say about ti exhaust and my J's in particular...
1 - don't buy a ti header... great for a racer w/ a budget that includes replacing their cracked headers often -- not great for the rest of us.
Stainless lasts.
2 - ti mufflers are almost as silly (from a practical stand point) - but they experience MUCH less heat and vibration -
so, if well built, have a decent failure rate.
3 - the J's is well built.
Did he have some issues? yeah, he would have built it differently, but he said for a commercially mass produced product it was pretty damn good.
He cut mine apart - found the all the pieces of ti mesh that were rattling around in my resonator - repacked (he did say it was packed like ass before) and re-welded the J's back together and it's as good (or probably better) than new...
here is the piece welded back together
So, yeah, they do sometimes fail for a daily driver - but not often - and they are very easily fixed by any commopetent ti welder.
Chris was great -- anyone that needs work done - give him a call...
He's been making exhaust lately for a euro conversion company that's putting B20's into the Lotus Elise
