Stupid 3" DP question

...but I'm gonna ask it anyway:

I'm having a reputable muffler shop do the 3" Diamond Eye install for me - I don't have the time or the wherewithal - and they claim to have done several before.
My question is, am I going to have a bulge in the floor boards or anything like that?
That would suck...

The fellow told me that he doesn't like having the owner's around while they "massage" the firewall to get it to fit.

How about the heat shiled, how important is it and is it something that I can do afterwards? Just some reflective furnace-type insultation around the pipe where it crosses the tranny?

So...she's in the shop today.

Guy calls me to inform me that there's a "soot buildup" along the backside of the engine block and has traced it to a leaking Y-pipe.
After a few hours, he calls again to tell me that the constant leak has burnt a groove into the pipe, so the Y-pipe needs to be replaced...as well as two special-grade bolts back there that were seized in place. Dealer doesn't have a pipe but will deliver tomorrow.

A $200 job just turned into a $700 one...


Oh well...."it's only money"!

Should have just done it yourself bud, and y pipe as in the one going in the heads from the turbo? I didn't have to touch anything to get my dp out/in aside from the hoist loop on the back side by the turbo

They're called up-pipes, and they go _from_ the _manifolds_ _to_ the turbo. They're leaking and need to be replaced; it has nothing to do with the downpipe install.

Correct. He spotted the soot buildup on the back of the engine AFTER removing the cobra head.
Due diligence led him to the gasket and the scored pipe...he said it would probably last another year or so, but then he'd have to pull the DP off (again) to access it and I agreed to just get it fixed now.

As for doing it myself, I don't do well when $hit goes sideways.... and when he mentioned the two bolts that were seized...I could just see myself losing it!


I'm just hoping that the end result will be as noticeable as everyone says it will...

$ 671 later...I have a new 3" DP and a new cross-pipe.

Driving tonight, pulled onto the highway...nice acceleration, definitely noticeable, but we'll have to see how it translates with a LOAD.

A bit noisier, especially when stopping...
