The nicks, cuts, head bonks and scrapes tally is way above normal for me on this job!! .

The big surprise is my back and shoulder-blades from laying on a concrete floor for hours and hours on end. I didn't see that one coming....

Wow, excellent write up, excellent detail on the fitment concern. I didn't have cats to send to S&S and therefore the cat protrusion was not known. I will contact S&S immediately and get this addressed. Apologies to everyone that has this problem. Giant thanks to Allan for this contribution.

Now, how does it RUN?

Jbrady,
From what I have been able to tell, BA GS400 is the first to to do install w/o removing engine mount bolts?? I'm not quite sure if it makes it easier but it seems to save some time. do you agree.

JBrady

Actually, I think the GS430 (and LS430, SC430) will be relatively easy and probably will not require engine mount removal. As far sas BA's work let him comment as I personally have NOT done this job. I have an LS400 and must fabricate a different Y pipe to use my headers and between this and other distractions haven't done the job. Therefore, the ones that have done this are the current install "experts".

super, Super, SUPER write up BA!!!!!!! I am printing this out now as I type! All this info will be VERY helpful for an install on a SC400 (albeit modified on some parts).
