    the bassani tru-dual hooks to the stock exhaust cats. removes the factory y-pipe and inserts a x-pipe in it's place.

    this link to my webpage shows how it hooks to the factory cats
    http://www.stealthram.com/bassanidualexhaust.htm

    this dyno graph compares the bassani tru-duals to a borla 3" adjustable exhaust. at the time of this test, the wife's car has bassani headers and their catted y-pipe. i modified the tru-duals to hook to the cats of fthe y-pipe. so, this dyn oshows just what you are asking. aftermarket y-pipe and cat back vs tru-duals

    There you are. You talked me into the Bassani setup with the pics and sound clips. I must admit, I love it. Best money I've spent so far. I've been spreading the news!

    Guess I should cancel my catback order

    My last question is this. With the duals can you run longtubes/cats/then the dual setup or does it have to be shorties/cats/then the dual setup?

    yes you can. just have to modify the bassani to hook up to your longtubes and cats.

    now, seeing as you are in california, by law, you cannot move the cats from the original location. so, you would have to buy JBA shorties that hook to the factory cats, then the bassani after the factory cats. thus, retaining the factory cats in their original location.

    Hey mrr23 or anyone else familiar with Bassani,,,,,how is the clearance with driveshaft loops and aftermarket torque arms?
    I assume this system is not too hard to hook to long tube headers with an off road y-pipe,,,can the bassani x-pipe still be used?

    The Bassani true duals system doesn't use a y-pipe, it's actually 2 seperate pipes from the cats to the rear bumper (except for the crossover). You have to adapt it to headers, it's made to hook up to the factory cats. So far as clearance, I haven't personally made it to the suspension mods yet. Those are next with the camshaft. I know there are people on several of the LS1 sites already running suspension upgrades with Bassani true duals though.

    the only driveshaft loop i know of that will work is the lakewood that bolts to the floor pan. the ones that bolt to the trans tunnel crossbrace location do not clear very well. i tried the bmr. to get it around the bassani, it would hit the stock torque arm. don't know about aftermarket torque arm clearance with a driveshaft loop.

    it will clear all torque arms that bolt to the transmission, or trans crossmember.

    pics of when i modified the bassani to fit my dynatech headers

    Thanks for those pics,,,helps a great deal. I can see exactly what you are talking about.
    I was figuring buying the long tube headers with an off road Y-pipe so I could use part of that Y-pipe and section it into the Bassani,,,but from your pics the Bassani looks as though it reaches far enough forward to connect to the long tubes with minimal fab work,,,,thats what I was worried about.

    Now I know I can just buy long tube headers and skip the y-pipe idea.
    Thanks man

    i don't mean to call you a liar or anything but i don't really know anyone on this forum and i was wondering how i know that the exhaust was borla 3" and not just the stock exh? i mean the torque and hp curves look elevated for a stock ws-6 but that doesn't have to be just exh. anyways i don't mean to be rude, thanks.

    well, first off, i do not have a WS6. it says right under my board name what cars i have.

    second. this is the internet. you will never be able to tell if someone is lying. you can do a google search for my screen name and find me on about 20+ message boards for the last, oh i don't know, six years, or so.

    now that we have that taken care of, here's the website i did for the wife's car. http://www.stealthram.com/1999pontiacformula.html

    never did a dyno run completely stock. put the borla on right as soon as we bought it. look on the timeslips page. you'll see every mod done to her car and the results.

    at the time of the borla vs bassani swap, the car had lid, filter, VHP MAF ends, vinci/crane 1.8 accelerated lift rockers, VHP ported heads, stock cam, bassani headers, and no cats.
