I finally got around to doing the Ti bypass mod on the car today. It was WELL worth the work. Sounds freaking fantastic! Mid-WOT is incredible sounding...

Here are a few pics...






Here is a before and after video - the videos do not do it justice. It sounds different (better) outside the shop and after the car has warmed up and idled down.

Inside the car did not change much - 6th gear on the highway sounds like stock but if its dropped down a gear or so you can hear it... its a good thing! =) not annoyong for sure!

 

that thing sounded good leaving the shop yesterday

 

Thanks Rob - I need to get some "fly-by" videos

 

next time you come by the shop i got my camera up there we can get some

 

i love the ti bypass, i heard one in person when i lived in chicago, sounded awesome.

why is the car smoking so bad

 

LOL... cold startup. It was kinda cool out that morning.

 

Do you happen to have any extra titanium conduit pipe? I have a TI exhaust sitting in my garage waiting for this mod to be done. I can't find anyone that supplies it other than on Ebay.

Thanks in advance,
Vince

 

Schweet work David! Hint- It'll put the little one to sleep in the car seat. At least it did for mine years ago.

 

PM sent!

 

Thanks man! Just leave the garage door open.. right?

 

Man that sounds great.
I now want to do the by-pass on mine.
How expensive was this mod to do?


Thanks in advance.

 

Well since I already have all of the equipment, it wasn't too bad. Cost me about $75. The reason people charge so much for it is because it is very time consuming!

Now the price of the equipment to do this is another story!!

Can this be done with standard flux core welding wire, or do you need to use a shielding gas?

It looks like the weld was brazed.

 

Unfortunately not with titanium. I wish, It would have turned a 2hr job into 5mins!! You have to tig weld it using 100% argon as a shielding gas, with Ti as a filler. Shielding the weld is super important with titanium. Back purging is also important but I do not find it necessary on an exhaust system....maybe if it was some nuclear type manifold supporting 35000psi lol

 

Do you have cats?

I can tell you even without cats, at cruise with the RPMs settled I get zero resonance. Sounds like a damn Machine gun under WOT.

 

No cats yep, crusing in 6th, no resonance, no interior noise... very nice and comfortable... WOT is just awesome.. my mpg has gone from 22 to 12mpg - LOL (because of the skinny pedal)
