    I'm running a Vibrant bottle-type resonator on my Alta Sportone exhaust right now... the larger Alta resonator didn't play nice w/ my B&M Short shift kit. That sucker has held up very well (knock on wood) and still looks solid after over 3 years of cruising way too close to the road surface.

    That is good to know.

    I'll have 2 of these 2.25x12 Stainless Steel Exhaust Resonator Vibrant Performance 1790

    and one of these 2.5x18 Stainless Steel Exhaust Resonator Vibrant Performance 17930

    Looks like I've got a smaller diameter version of your 18" resonator. It's been great and gives plenty of clearance.

    Here's a pic from a long while ago when they were welding up the Vibrant to the Alta kit (Alta resonator on the right).

    I've melted the perforated core of two Vibrant resonators.

    My exhaust was VERY loud, so in conjunction with my Alta stuff I added a glass pack, installed it backwards, so it does not restrict as much. Sounds great and seems to be holding up well?

    So Nathan, you are going to run 2 resonators instead of mufflers in a JCW/Borla orientation?

    The current setup is 2 x 12" Hushpower resonators in the back with an 18" Hushpower resonator in the center. The new setup will replace the Hushpower units with Vibrant Performance ones.

    I'll dig around and see if I have any pictures of the Hushpower setup.

    This was the only image I could find. It's not the best and well was to show a break, not the full setup but you can get an idea from this.

    Since I've not heard from Chad there no real updates from him, but that doesn't mean there is no news.

    Not that really exciting stuff, more procedural.

    Have tracking info on the exhaust parts that will be trucked up Middle America via FedEx Ground.

    Way shipped the brake rotors to Chad. These are some well traveled rotors so far. From Coleman in MI to ATL back to MI. Efficient use of resources here!

    I am having the same problems with my car... #1 Cyl is 140, #2 Cyl is 85, #3 Cyl is 135 and #4 Cyl is 140...
    I have been saving money to send the car to Jan but everytime I get close to having the money I spend it... My 16 yr old needed a car and then I found a 1968 Camaro that had my name all over it...
    I think that the key to a rebuild of this caliber is having a mechanic that is willing to go above and beyond... Just my two cents...
    Good Luck Nathan!!! I miss seeing ya!!! TW

    Scott, you got me on this one. I went looking for muffler vs resonator information and all I could find was a bunch of speculation. Not sure what the real differences are and in what situation each is ideally used.

    Hopefully someone can edumacate us!

    A resonator is for sound attenuation, and a muffler is for sound reduction to a specified acceptable level.

    The resonator can before or after the muffler, or not at all....

    So then what about some of us using only resonators and no mufflers. How does that affect the sound?

    It's obvious Chad is watching this thread.

    Sent me a pic of the current exhaust so we can compare the look after the new bits go in.

    [​IMG]

    For those playing the home game...

    Thats a race header, 2.5" dia out into a race cat to an 18" long blown-out Hushpower resonator then split, reduced to 2.25" then sent through a 12" long blown-out Hushpower resonator on each side, finally exiting via Thermal R&D Exhaust Tips built from T304 stainless steel and hand crafted with a high luster polish.

    The new version will be a race header, 2.5" dia out into a race cat to an 18" Vibrant Performance bottle type resonator then split, reduced to 2.25" then sent through a 12" Vibrant Performance bottle type resonator on each side, finally exiting via Thermal R&D Exhaust Tips built from T304 stainless steel and hand crafted with a high luster polish.

    Not to change the subject yet again, but those donuts on the back are seriously shot. Time for new donuts Nathan! Don't do what a friend of mine once did. Saved money on tires only to cost himself a car. True story.

    Good eye. yep, looks like the inside edge of the rears are scalloped. And no small potatoes.

    Might be an excuse for a wheel change too...

    Anyone want to do some horse trading? Work VS-XX 17x7.5 Polished Lip, Custom Painted centers. Need a good cleaning and one is slightly curbed just a tiny bit.

    Pics here: http://www.motoringalliance.com/forums/member-garages/8311-gnat-2006-mini-cooper-s.html#ixzz1rsATRy2Z


    Chad recently sent over this, hopefully Matt will polish those tanks before the engine goes back in. Sure are a lot easier to get to right now.
