1997 NAS D90 Y-Pipe (ESR4106) on a 1995 NAS D90??

The cats in my 95 NAS D90 have been rattling badly for a while. I took it to a exhaust shop that I've used before, thinking that I'd just cut the cats out and weld straight pipes back in. He was hesitant to touch it - due to the tight clearances and the amount of rust in the original y-pipe. So, he suggested that I replace the entire y-pipe and cat assembly.

But he had issues finding stock - so I looked around and eventually got one sent to me from a Canadian auto parts place that I use. The part that showed up has four O2 sensor ports and a ESR4106 part number (for a 97 D90). When we put the Defender on the hoist and measured things - it seems like this part will interfere with the tubular cross-member. He's worried to tear it apart and try to fit it - since it appears that my current y-pipe may just dissolve into a pile of rust coloured shards.

I sent an email to the parts supplier and they said that although the part number is for the later model - they are told it will fit. The exhaust guy thinks otherwise.

I have a friend down the road with a 97 NAS D90 and I laid on my back and looked at both vehicles and was surprised to see that it *appears* that the cross-member is in the same spot, the part numbers for the exhaust manifolds are the same and the connection to the cat-back section of the exhaust is very close to the same position. I was expecting the cross-member to be in a different position or to see some other differences. Comparing to the 97, it almost appears like it might fit. But laying on my back in the (somewhat) cold isn't proof.

I searched and read here for a while - but never saw anybody definitely state whether an ESR4106 (97) could be installed in place of the ESR3063 (95).

So - should I send the ESR4106 back and demand a refund and return shipping? Or should I find a new exhaust shop? Or try to fit it myself (I was anticipating lots of broken bolts etc..., I usually let others do my exhaust work)?!?

What started as a simple exhaust rattle is becoming a PITA... I may just continue to live with the rattle!

Thanks for any advice...

It will fit. Just plug up the holes you don't need.

Thanks. After looking at the 97 - I was thinking it would fit. But I think it's also going to be a one-way street taking it out. Before I start taking it apart myself, I may go to another shop I've used and see what they say...
