View Full Version : Borla Install Help

ok - finally going to around to putting my borla exhaust on.


I want to replace the bolts and nuts from cat to down pipe. Anything special i need? what size are they? copper? All I can find on ECS is for the manifold.

nothing special, i actually just replaced mine last night. Make sure you get some crush washers so it makes it easier putting it back on as i failed to do. Also you are going to want to find ones that dont rust, so when you need to take it off again it makes it much easier

Just finished installing a Borla, I used M8-35mm bolts/nuts, 316 stainless steel from McMaster Carr with anti-seize applied to the bolts.

all u need to do is go to the dealer and get w.e bolts are there normally, if ur exhaust has been on there for a long time (oem) i would sudgest getting new ones incase one of yours breaks when you un doo them, and its nice to replace with new ones

I just took one of the old ones to Lowes and got some stainless steel ones in same size...

Thanks - I usually try not to go to the dealer even though its only a block away. Might just call and see how much they are. otherwise I'll pick up some stainless in the size suggested, already have some anti-seize from doing the TB job.
