If you want a job done properly, do it yourself
I had some hi flow cats installed by TL Jaguar last year.
https://www.jaguarforums.com/forum/x...upgrade-93043/
They had issues with the exhaust clamps connecting the cats to the rest the of the exhaust system, my car had to stay with them for another day so they could fix the leak.
Anyway they called me when it was fixed and I collected the car and drove off. The sound wasn't quite what I expected but convinced myself that it sounded great due to the fact I just handed over quite a considerable amount of money, plus TL Jaguar assured me the problem with the exhaust had been fixed.
The new exhaust did sound pretty good but there was this unpleasant tinny note which sounded similar to a cracked exhaust manifold.
I inspected the installation of the new cats when I got home, everything felt solid so for the past year I have been thinking this was a quirk with the high flow cats and lived with it.
About a week ago there was a definite blowing sound coming from the left of the engine bay, especially when cold. Enough was enough, so yesterday I decided to take the cat off to inspect it. I was expecting maybe something was loose inside the cat, anyway, as soon as I got my hands on it I could see there was a very small amount of play. I proceeded to remove the cat and found out exactly was been causing this annoying sound since I picked up my car from TL Jaguar
From what I could see there had been a leak between the exhaust manifold and cat all this time due to the fact the retaining clamp was not securely fastened. The clamp must have slowly worked loose over the past year as one of the manifold stud threads had been completely stripped!!!!!!!!!
Due to the severity of the thread stripping I am absolutely certain that who ever tightened up that nut knew it must have been occurring at the time but decided not too do anything about it and forced the nut round anyway, if the stud was damaged on removal of the old cat then it should have been replaced.
After a visit to my local Jag garage I picked up a pair of studs and nuts (£20 per set!). I have just fitted the cat and took the car out for a test drive. The tinny leaky sound has completely gone! The car sounds brilliant!
As you can imagine I'm not too happy with the quality of workmanship from TL Jaguar and just goes to show that if you want a job doing properly you have to do it yourself.
