exhaust problems
i have 2 1/2 inch pipes that start off from the cats with a magnaflow x pipe, 2 resignators,magnaflow universal exhaust boxes.......my car is having launching problems and the top end is not so great.....i want to know what kind of setup or exhaust can i put to get my power back.....my mods on the car are......performance intake from jaguar xp, performance pulley from xp, and ecu tuning from a buddy of mine. i need some serious help........my nearby performance exhaust shop said i have no back pressure and told me to put an exhaust brand called vibrant........i told him with 2 big resignators how can i have no back pressure....then he said its my magnaflow exhausts are too weak to be put on my car.....can some1 help me with my problem plzzzzz.

RE: exhaust problems
You have made numerous changes to the car. These cars are computer controlled and with all the changes you have made, the computer may not function properly being confused with all the inputs it was not designed for. I put the XP cold air intake on my XJ8 and had to remove it as it would set off the CEL constantly. Just can't go too far with these cars.

RE: exhaust problems
the spark plugs have ben changed a month ago.....and this problem started after i put the cheap magnaflow exhausts from a place that knew nothing about performance.....i was going to go with arden but my performance exhaust guy that a refered me to told me that arden is made for stock str setups only so he said its going to be a waste of money. i dono, i'm prob gonna sell this p.o.s and maybe go buy myself a e55 amg

Put some ice on those nuts! I don't think the issue here is the car, but what has been done to it that has made it P.O.S. Blame that car, not all Jags. Cars are so sofisticated these days, you can't do so much to it and expect the operation of the computers and sensors to perform well.[sm=badidea.gif]

RE: exhaust problems
What exhaust did you end up with? I would also like a "DEEPER POWER SOUND"
for my 01 XJ8, and was thinking of changing the mufflers to the Magna-flows,
because they sound GREAT on my other cars, with no tuning problems, bad idea
for the Jag? and will I have to do some ECUtuning for this mod? TIA Alex
