    Had a look on the furum for some information about the cat lengths on the supercharged ecotec's and cant find what i need also searched google as well and found nothing.

    i have a 2000 vt supercharge ecotec looking at upgrading the exhaust i have a set of extractors (pacemakers) on it already but everything from the cat back is standard looking at the 2.5" twin system from redback but want to change the cats. just wondering what cats to look at???

    Thanks guys

    If you already have Pacemakers on the car, the stock cats will have been modded to match unless it already has pacemaker pre made cat sections. Stock cats are the best imo unless you are making over 230rwkw. Sound good and work fine

    If the cats are stuffed, then replace them, if not, leave them. The cat back will bolt straight up. Nobody makes a bolt in cat for the V6 off Pacemaker extractors. The closest I've seen are the Manta cats to suit V8 tri Y's, same flanges but about 50mm short on the front.

    I hope you won't be disappointed with the Redback twin, they can be very raspy on the L67.

    I think to answer your question the L67 cats are the same as a stock ecotech or LS1. Generally Holden use the same cats and CPI count.

    I dont know why you want to know this you either run stock cats or hi-flow's the length wont affect performance enough to notice.

    It wasn't too bad with the standard cats. With the hi-flow's in the rear Resi seemed to distort n sounded like ass lol, it's a V6 it'll never sound that good

    Sorry to over take the thread but is it possible to fit a ls1 twin exhaust to a car that only has the single 1 cat style exhaust?

    Yes, but it won't bolt straight up. You will need to cut the front up and make it single, or fit twin cats.

    It's the same body that has twin cats when a different engine is fitted so twin cats will fit. You just need to find some.

    Sorry to revive an old thread, but this seems to be the place to ask it, I’ve picked up some stocko ls1 cats and want to chuck them on my s1 vy v6, I wanna ditch the stupid y piece and put the cats on and bolt an ss system to it. Will ls1 cats bolt onto my headers or will they need to be modded
