    I made this when I got the Tubis. https://www.youtube.com/watch?v=EDud9VlbPAM

    Not as raucous as the Larini back boxes but much more tuneful and interesting than factory.

    I ought to drop in here that I have some nice straight through rear pipes if anyone is interested. Looking for £300 posted. Can email photos etc

    They are nicely made and the tips look like stock, with all standard cats my car sounded like this:

    Should get my quote tomorrow for new 100 cell cats centre section H to connect up with rear boxes, all in 2 1/2 inch stainless. Still need to know about whether to replace the exhaust heat sensors (if that's what they are - #3 in the diagram). Any ideas guys?

    Those are exhaust gas temperature senders. The ones with a metal braided outer, and s screw on fitting etc

    I Didn't replace mine when I fitted an all new system, but I did replace all 4 Lambda sensors.

    I wouldn't see any need to replace them unless they look damaged at the probe tip, or the car is throwing a code that pertains to them.

    Yeah thanks, thin braided lines. I guess I was wondering whether they need refitting in the new centre section pipes or can I delete them too? Never heard of a fault code from them but that doesn't mean much. Also wondering what removing the precats will do for exhaust temps at those sensors? Hotter?

    Personally I wouldn't remove them. They are your last line of defence for protection, excessively high EGT's on a turbo engine are not good.

    Removing the pre cat's should help to ease the temps though, I suppose to a degree that the temp senders help to protect the cat's.

    have you had a read of the repair manual? It will explain the operation logic of the EGT sensors etc

    No, but I'll dig it out. No point tempting fate. Cheers.

    Straight pipes on rear instead of boxes makes more noise, straight pipes on centre makes more noise, maybe less power? Xpipe on centre with rear boxes removed is the best solution in my experience performance wise straight pipes has no scavenging effect which might be marginal on an NA application but a boosted one it does make a difference so keep the merge if u want performance but the sound from a dual system will always be better I have done both by the way
