Honestly we didn't test them seperately. I would imagine they made a difference as the stock pipes are about 1.5" at the neck. I'd say it's a worth while mod for any E55 stock or modded.

I posted a short video of me doing a run last night from about 20 - 110.
I am hoping to get the car to the track Friday night, but I have pretty beat tires on the car, and I have only driven on the 1/4 mile track a total of 3 passes ever. keep you posted.

Also, Anthony from TVT is a stand up guy and very easy to work with. I felt very comfortable with him from the first time I spoke to him. And, from the time I dropped my car off to him, he followed through on every single thing he promised and said he would do. He even went above and beyond on a number of small issues he found with the car.
If anyone is considering using TVT in the future, feel free to contact me personally for a more in depth review of them. ANd, if you would like to see or take a ride in my car, I am more than happy to help out.
I'm not disputing whatever performance gains you're claiming; you simply misstated some facts on the stock exhaust.
What's the appearance of the resonator have to do with anything?

Are you measuring the O.D. or the I.D.?
It opens up the bottle neck after the filters where the tubes start at 3" and taper down to 1.5". It's a non-CF alternative to the Python tubes, and a tad more affordable.






Does that bigger volume of air coupled with some filters or stock filters equate to more whine as well along with the new 180mm pulley?
