Exhaust Diameter
Discussion
Hi guys
I have a vxr8, the previous owner has removed the center silencer and has replaced it with straight pipes, but they did not flair the end of the pipes to make a male or female connection so they have welded the replacement pipes together, but these joints won't hold.
So i need to sleave the joints, but I am not sure of the diameter of the pipes without jacking the car up, so can somebody tell me the diameter of the pipes and save me the hassle.
Cheers.

Why do you think a welded pipe wont hold ? That's how metal is joined together....welded.I have a vxr8, the previous owner has removed the center silencer and has replaced it with straight pipes, but they did not flair the end of the pipes to make a male or female connection so they have welded the replacement pipes together, but these joints won't hold.

Hi there , the pipe has been welded twice by different guys, with no luck.
I think to do the job properly the system would need to come off, using sleaves they are just bolt on
There is no issue welding pipes.I think to do the job properly the system would need to come off, using sleaves they are just bolt on
Now if the exhaust is not hung properly, something not aligned properly...or the welding is just ste. That is a problem.
But not a single thing wrong with welding two bits together. It does not need sleeved or anything like it.
Although if you were really stuck and cant be arsed welding anything....and you could cut the weld out without it affecting length...ie to create a new butt joint. You can get joint clamps to join two pieces together like that.

Completely agree. Welding pipe is normal, but being in construction and around a lot of metal and pipe welders there is a huge difference between a decent pipe welder and your average Joe back yard job.Now if the exhaust is not hung properly, something not aligned properly...or the welding is just ste.

Best bet is to go to an exhaust place, cut out offending weld. If it’s had a few dodgies the gaps probably too big now after a clean up so an insert section will be needed.

Whilst true....I've seen some absolutely terrible welds holding for many many years. Even worse than my own welding, and never in 20+ years has one of mine cracked or broke.Best bet is to go to an exhaust place, cut out offending weld.

IMO, the weld is very unlikely to be the problem, but exhaust fitment and alignment etc, is very likely. Any joint under a lot of stress, will fail.
