Hi all,

I'm not sure if this is allowed, if not please delete thread admin. Over the weekend I'll be installing some MBH long tubes on my 55 and I'll be looking at selling my primary cats if anyone is interested. They will need to be welded but I'm sure you already know this. The car only has 24k miles. Open to sensible offers.

I am not interested in the CAT's but I am interested in hearing how the install goes and if you are happy with the results. I am thinking of doing this myself but cost plus concern with fit-up is holding me back.

Already done it, same set up as he plans. Sounds great and NO DRONE. You must tune afterwards however and since that's required, you may as well as a smaller SC pulley.
Do those things and add 100+hp and > 100 lb ft of torque. Whole different car!

I'll update this for sure, I'm just going with the MBH long tubes for now, keeping secondaries, resonators and mufflers on the car. Vtech are tuning the car for me, doing the engine mounts as well whilst im there... Upgrading to black series mounts, I'm sure with 24k miles mine are probably not too bad but hey, it's one of those whilst you're in there jobs.
