Ok, so I have the 96 XJ6 4.0L. I think there is a whole somewhere in the exhaust pipe. The mufflers on the duals on the back end of the car look clean. I have looked and I cannot find this hole on the exhaust. I dont know, it could be on the catalytic converter I guess? Not sure though. So, I was considering changing the exhaust out, and I am looking to get more of the European purr from the car. Is there an after market system I could use, and if so what one do you think would be best for it? I've noticed most the basic XJ6's sound kind of quiet I don't want the rice burner sound, and I dont want it super loud just want it to purr a little when I give it gas. . . I'll see if I can find a link to show you what I mean.


Thanks Gents!

 

I believe these X300 cars could get cracks in the exhaust manifold, and it was difficult to detect because there is a cover over it. Worth a look, maybe.

 

Oh ok, I didn't even think of that. I will check that out. Is there any way to patch that as a temporary fix if until I can replace the whole thing just to quiet the car down? Like would JB Weld do the job?

 

Jb weld might work,also check your oxygen sensor(have had 2 manifolds that cracked arround the unit).

 

Gents. I have looked this car over & nothing? No idea where it's coming from? I am thinking I may just need to replace everything! UGH!

 

Jeff, the best time to check for this would be when the car is very cold at start up first thing, keep us posted ....

 

Yeah, I jaked the car up ran my hand over the muffler...looked at manifold. No idea, it's quiet, but when accelerating it's louder than I believe it's supposed to be. I'll have to have it looked at by a shop in thinking!?! I'll let everyone know what happens in the next week or so once I take it in.
