1995 LWB . just developed a rattling cat; the one on the drivers side. the local good exhaust guy says he will put a new one In for me. Which one do I buy? Magnaflow or eastern or someone else. I'm looking for the closest sized one to my original. any experience out there? thx geneo

MY 09SC repeatedly gave cat faults, diagnosed by different independent LR garages. (175 000km's) Post a reset they would reappear after +/- 400km's We have no legal obligation to have cats, so i took the plunge of having them removed, as replacement cost is unjustifiably high. Moral debate...

Apparently OBD code 1170 is also attributable to a hairline crack on the catalytic converter, I have heard of possible repairs to this problem, does anyone know how to detect it and how to repair it? Please any thought would be appreciated. Tks Lou

Just wondering if anyone has any experience with deleting the cats from their exhaust in the P38s. I plan to cut out the whole cat and just re connect with pipe, any loss of torque? Or maybe fuel mileage gains? Thanks

Does anyone have one? I'm currently looking at the universal Magnaflow one for my 2002, just wanted to know if there were any better options out there... Can they be directly welded on without disturbing the O2 sensor threads? The Magnaflows don't look like they're shaped exactly like the OE...

Any of you guys running something that sounds a little better? I'd like a little more rumble without being too loud or droning obviously. Plus the tips are too small IMO. Get me some pics, pricing, and sound clips if you have em!

Hi Internet First post so i'll say a quick hello and thank you. I bought my 1999 4.6 hse a couple of months ago VERY cheap with an EAS fault and thanks to the search I've managed to get it going (valve block rebuild, replaced knackered driver, manually operating with jumpers, new thermal cutoff...

Got a new CEL randomly while driving for a few hours, p0420. From searching online, it sounds like its either from a bad 02 sensor or bad cat converter, but most likely the cat converter. I cleared the code so we'll see if it pops up again but could my cat converter already be going bad on an...

Hi, (I'm a newbie!), I have a '88 RR that's been sitting around in the garage for a few years. It has bad O2 sensors and a bad cat. Now that it's 25 years old, I don't have to run it through emissions anymore. My question is: if I hack off the cat, is there something that I need to do to the...
