Volvo Repair Database 1999 V70T5M exhaust pipe diameter between cat and front muffler

Post by abscate » Sat Oct 07, 2017 11:32 am

I made a deal with my other cars not to break until my clutch job on the P to V 70 was complete. Now that that's done, the beetle through a cooling group code, the transporter threw an evap code, but that's all fair in love and war. Now to the 1999 V70 issue. I have an exhaust hole between the cat out front muffler, can someone save me a roll under the car and know the diameter of the pipe? I'll I will probably just flange this rather than cut and weld since the pipe is sound. Thanks in advance

IIRC- from perusing cats online, grumpy and other, 2.0 for N/A, 2.25 for turbo. Use the mouse, spare the creeper.
Current Volvos:
1998 V70 T5, 112k sat 5 years, still in mechanical coma (finally at the top of the pile )
2004 XC90 T6 AWD: 186k, 60 on transaxle ( traded in )
1998 POS70 N/A: DD/training aid, 236k but really about 240k, I think...ABS module( passed on to son who sold it)

Stainless steel band clamps sometimes do an awesome job - at least if a bend isn't involved.
Wisdom requires knowledge as a prerequisite, but knowledge can be developed due to a lack of wisdom.
In order to learn how to fix something, you must first learn how to break it.

Mine is kind of inbetween 2.25 inches and 2.5 inches but less than 2.5 inches

Going to try some Permatex epoxy muffler bandage and clamps and see how it looks

Grumpy cats.

I redid this job with exhaustwrap and my Walker 33976 aluminized clamp the other day in about 10 minutes. Muffler system is really quiet now.

JB Weld the clamp over the defect. The muffler bandage will deteriorate over time. JB Weld and clamp is a permanent fix.
