    Any benefit in swapping cat with straight pipe?

    I still have a full stock exhaust setup and not sure i want to replace it at this time. I have swapped out the cat on my old 300 TT with a "off road pipe" and it gave some extra HP. If I have a full stock exhaust setup, is there any benefit/gain in just getting rid of the cat and going with a...

    Dealer wants to install another rope seal for rear?

    I am trying to get my rear main leak fixed. A buddy backed out of doing the job since he did not feel comfortable doing a rope seal. A local tuner shop did not want to do it stating "it will just leak again." So now I contact about the only dealer I would somewhat feel comfortable doing the...

    Those of you who changed rear main-still leak?

    Just spoke with a mechanic that told me even if I replace the rear main with a neoprene seal that the car will still leak. He said these cars are prone to leaking from the rear main. They swapped one out 3 times just to see if it would make a difference and it still leaked. Those of you who...

    Queston on insulated panel/cover 4 fuse panel drivers side

    The panel that is insulated and covers the fuse box on the drivers side sags in the middle. Is this common on these cars? The way the holes line up, it seems that would be natural to sag but it drives me nuts. I tried to tuck the middle part under the dash to hold, but that does not work...

    Advise on removing something on paint

    The GN I recently bought has a few small sections that are on the rocker panels which looks like flat black paint. It looks like one of the previous owners tried touching up with a dull flat black. I have used a Zymol product that strips similar to a clay bar and this is doing the job but...

    ? on ScanMaster wiring-turn on headlights turns off SM

    I posted a quick thread on this before and still can't figure this out. I have the ScanMaster powered into the fuse box into the IGN open port. Everytime I turn on the headlights it shuts power to the ScanMaster. I have tried every IGN port and they all do the same thing. Anyone have an idea...

    Suggestions for more boost/power on stock GN

    I want to keep my GN mostly stock, but would like to add some HP to the mix. I have an intake, chip, 340 fuel pump hotwired. Would an adjustable wastegate and adjustable fuel pressure regulater be the next option? If so, what additional HP could be expected? Currently I can only get about 15...

    Still new to the GN world and have my ScanMaster hooked up and need to adjust the throttle position sensor. I know it is located on the trottle body, but where and what does it look like? For that matter which way do I go with it? I read it is a set screw, but I don't see any adjustable...

    Is it possible to have 0 knock?

    Just installed a Scan Master and knock gauge, and both are reading zero knock. I called Caspers and they said I could be getting either 0 knock or maybe my sensor wire is bad. My car is not much more than stock. It has a Joe Lubrant chip, Big Mouth intake, Walbro 340 and that is about it...

    How much to repair rear seal leak?

    This seems to be a common place for GN's to leak oil and I think I have a small leak. At this point, tend to believe a rear main seal. How much is about normal for a shop to fix?
