    Re: CSi Exhaust?

    I am not the leat bit impressed by the factory exhaust on my CSi

    In fact M73 was better

    I am, in fact in search of headers.

    If I cannot obtain those, I will at least extrude hone the exhaust when I do theads. Not sure about dyno results, but I have proven that make sthe engine mor eefficient on myu M73.

    Cheers

    Here you go... Each tip is made out of 3 mm thick stainless steel with an outside diameter of 76 mm. The polished and straight part of the tips is 135 mm long. The distance between the tips is 15 mm and the outer tips are 25 mm recessed (staggered setup).

    I had brackets welded to my Magnaflows (more)

    Stupid enter key...

    to make installation bolt-on. I can take a pic if you want. I'll have to squeeze under, my 8 is lowered.

    The thing you guys missed is .....

    to remember to put used parts or sample or cheap cost of parts on the green customs label, otherwise we get hammered on duty. I got stiffed to the tune of 170 on a set of luggage I bought on ebay from the states. Didnt help the fact that the box had Ferrari written all over it.

    I am not in a hurry so dont mind waiting a couple of weeks. I'm all for safety in this day and age.

    Thanks Laszlo et al. I will go for just the rear mufflers I think. Will contact my local exhaust fitters to see how much they will charge for installation- just a bit worried about the welding.

    I shipped a package to GerryUKCSi, only 2 weeks

    Left here 2/22 arrived at Gerry's 3/06.
    Maybe I was lucky? I was able to track it, no problems at all.

    Re: isn't royal mail who handles international parcels

    Well as I said our part of the arrangement went well (USPS) as you saw with your Saudi client. The breakdown happens in-country and our system is essentially out of the loop at that point. To compound matters, remember the bad bomb scare at Heathrow last Christmas time? They are just now beginning to see the light of day from the backlog created by increased security and inspection much like happened after 9/11. Add to that the international disruption from the Icelandic volcano. The ParcelForce compound is the single largest building in the UK... given the propensity for human error,laziness, or inefficiency it's easy to see how the process of our little transactions can be really held up. I'm sticking with the more streamlined process of good 'ol FedEx.

    isn't royal mail who handles international parcels

    anymore ? I guess that explains recent troubles with that. a Saudi Arabian buyer of me got his parcel into the country in 4 days but delivery to his hometown took an another 10 days.
    I see your point and I think it is a typical - contract work. The winner of a contract is always the cheapest, not the best.

    oh well, an another good service that gets bent out of shape due to the economic downturn that our government orchestrated.

    A note Lazslo about your mention of USPS for...

    .... shipping to the UK. If you do use it then expect abnormal delays, and forget using the guaranteed delivery option: it's an expensive joke. You see, USPS does their job getting something there fast (the most recent case an E31 radiator), but things bog down at ParcelForce which has the handling agreement with USPS for everything and is part of the customs system (according to USPS-but they're essentially a contractor with exclusivity) Items can be hung up for two weeks or more... they get there eventually but patience can get short and you look like the bad guy. I've had no issues whatsoever things going to Ireland for instance, but never again will I use USPS to send to the UK. It's your call... they are relatively inexpensive but I feel it's false economy.

    wow, lots of questions :-) I try and answer all

    the X-pipe in place of a factory resonator (which is a functional x-pipe) is to make the system a bit more loud and lighter.

    The muffler is also same benefits, more noise and looks fancy and less weight.

    The downside is you can actually loose back pressure and low end torque with too free of an exhaust and you can actually have too much noise (unless you are 18-20 y/o will not like that)

    My suggestion is for 840 owners and from experience : leave the factory resonator in place and replace the end mufflers with the magnaflow.
    or leave the factory mufflers and replace the resonator with x-pipe but do not do both. too loud, not enough back pressure.

    850 owners however reported moderate noise level with x-pipe and magnaflow mufflers. they also did not report any power loss either. It must be due to the different firing order and the nature of the V12 engine... I can not test it in person so I'm not going to make a statement on that.

    You do need to fabricate a rear pipe for the mufflers, cost me 140usd for a pair total - incl the pipes, the hangers, install, etc. welded system.
    I also have a pair of resonators on each side to quiet it down which were an additional 45usd each. (hence the reason I do not recommend removing the factory resonator, you end up with an another resonator on the 840's pretty soon)

    a pair of magnaflow is around 144-165 usd each and the x-pipe is about 85 usd.

    go onto the magnaflow's website - www.magnaflow.com and choose what you like and email me the part #'s.

    Shipping should not be much, we could use the good ol' post office (royal mail for UK) and they are reasonably inexpensive and fairly quick too.

    we should discuss the rest of the details in the emails, so avoid pissing off the rest of the members with business deals :-)

    My email is on the top, just shoot me an email and I forward the prices to you along with some pictures. I have a set of magnaflow with an X-pipe and individual resonators. I can take a picture of my system.

    There is a youtube video of the car starting and revving up... if I can remember what was the title... :-)

    Hi Laszlo - what about shipping for us guys in UK?

    I need 2 - am not really bothered if they have square or round tips but would like the polished stainless steel look. Do I have to fabricate the hanging clips by welding on to the back boxes?

    I understand that he original mufflers are somewhat assymetric. The left side is a standard bolt off bolt on but the RHS has a longer pipe which is welded with a sleeve before reaching the centre resonator.

    Do you supply an x-pipe? What are the pros an cons of deleting the centre resonator using straight pipes or replacing with an x pipe?

    Thanks.

    I agree. The Ci tip is actually square and this

    magnaflow here also comes with square tip. Not exactly same but you get the picture :-)



    Part # 14833

    cost is $169.95 plus about 10usd for shipping (from me) . Jegs and Summit is more, but nobody can advertise any lower price then MSRP on Magnaflow.

    Much easier: get the 840 tips. In my experience...

    .... even a trashed rusted out exhaust from these cars (both V8 and V12)leaves the tips in great shape as they are heavy gauge steel. IMO the V8 tips have the proper compound stagger. Adding the 850 tips to magnaflows is a great mod, and the same would hold for V8 ones. Unless this were a faithful restoration or maintenance of an actual CSI I can't see how you could justify the expense.

    Re: magnaflow tmufflers and tips

    the Magnaflows were an awesome price, they only ran me about $90 per can. I got part number 12158 from Jegs.com.

    That's an error in the ETK. The part number given is for the rectangular chrome tips of the 850i and 850Ci - not the round stainless steel tips from the 850CSi. As far as I know the 850CSi tips are not even available separately - they are part of the mufflers. There was a discussion about it recently at 8er.org in the topic Bying original mufflers for 850CSI (forum requires registration, but is free). Displayed below is the left 850CSi muffler:



    I do not have the dimensions at hand, but if no one else responds I'll measure them one of these days.

    Re: magnaflow tmufflers and tips

    How much were the magnaflows and what model did you go for? Are you going to attach the csi tips from gault or cut and weld?

    I am in Uk and am trying to get magnaflows or stock mufflers. Can anyone outhere help me please?

    Re: fwiw - I gave Gault my VIN when I ordered

    Finished the paint this weekend. Gonna give it a couple of days, then buff it before install.

    Jef, how much did they charge for the paint? By the time I got the paint supplies and my time spent I'd guess mine cost more! But painting is something I enjoy so.....

    Re: CSi Tips?

    I found the tips on Realoem.com (part number 82119401152.) The only thing is, it says that they're "chrome?" Weren't the CSi tips stainless steel? Because I've seen that CSi for sale on eBay (the one that started out at like $95K and is now like $79k) and those tips dont look chrome to me. Anybody have any insight? Thanks

    CSi Tips?

    I ordered the Magnaflow cans and got them in. I've been shopping around for tips to put on the cans, and for some reason, I'm really drawn to the CSi tips. Does anyone know the measurements of those tips? Length? Diameter? I know they're staggered so if someone could tell me the length of the shorter one and the longer one that would be great, but I'm sure the muffler shop that I go to would at least be able to ballpark it. Any help always appreciated. Thanks guys.
