Not sure of the size but I will tell you that I took my old cats to a recycle center and got $120 for one and $85 for the other!!!!

 

Not bad at all, thats more than 1/2 of what I paid for the new ones.

I think for the bolts I will just have to grab a few different sizes, any idea if they are metric or english?

 

I got my new y-pipe and noticed that it doesn't have a heat shield on the drivers side cat. I guess i'll be putting in my CDL instead this weekend. I contacted the seller, i'll keep the thread updated for anybody who is in the market for one of these.

Unless i'm seeing things the ebay listing image definitely shows a heat shield on there...

Here are some pics of mine.

 

Yup, that's exactly how mine unit showed up at the door, no heat shield. Have fun peeling that sticker off the drivers side cat. I think mine is still burning off.

 

Have you had issues with anything around the cats getting too hot?

 

James,
I have had mine on for about 5 months now and do not have the heat shield and have had no issues.

I will tell you that it is a little louder since they are smaller cats though.

 

Agreed. It is a bit louder (more of a hollowed out sound). To date I've had no issues with heat.

 

Thanks for the feedback guys.
