I didn't find any other physical differences. The Si axle was the same diameter as the Sport.I'm glad this worked out for you. I was planning on installing just the LSD from the Si into my Sport as well. I know they share the transmission cases so the Si LSD should just drop in with the Si ring gear. Judging from parts numbers and descriptions alone, I found (and you confirmed) the inboard Si CV joints are larger than the Sport, but I wasn't sure about the hub and knuckle compatibility. The Si and Sport hubs are different part numbers, but the same wheel bearing. If anything, I though you might need Si hubs for the conversion as well. Good to know the Si axles fit in the Sport knuckles/hubs.
Aside from the larger splined part of the Si axles, could you find any other physical differences? Was the Si axle a larger diameter? I was thinking of just getting the Si driver's axle and the passenger intermediate shaft. Does the Sport passenger axle work with the Si intermediate shaft?
You're right I haven't put it on yet. My friends think I'm nuts for not slapping that thing on the car as soon as I got it lol. They don't understand it needs a tune and its a long process doing a etune. I also want to make sure I have all the bolt ons I want before I do the tune.A month with the 27 Won but you havne't put it on yet?
You are a patient man, assuming the RV6 arrived and you threw the DP/FP - how did the PLM work - and are rocking a fast ass car now capable of low 12's?
I have the Redline 360 2.5" DP and FP and stock exhaust but added a 12" glasspack for the cold starts as it was waking the wife and baby up when i left for owrk, the little 12" glasspack changed the tone and dropped it down I LOVE the sound now... Prior to the glasspack, and with the glasspack I have had NO smells, so not sure why you are getting a smell man? Rode in several other 10th gens and no smells in thiers as well....You're right I haven't put it on yet. My friends think I'm nuts for not slapping that thing on the car as soon as I got it lol.

I have been working on the exhaust. Once I get that setup the way I want I will put the turbo in.
The RV6 combo didn't happen. I went with the PRL downpipe and the PLM frontpipe. The downpipe was on a 4 week back order that I didn't know about when I ordered it (I didn't order it from PRL).
When it finally showed up I tossed it in the car with the PLM frontpipe. I ran in to few more problems. The PLM didn't fit (no surprise there lol) so I took that off and put the stock frontpipe back on.
The second problem was that I had a resonator delete. I learned that a catless downpipe and no resonator sound HORRIBLE on this car. So I had the stock resonator welded back in and that made it sound way better but I ended up deciding to get a new exhaust. So I now have a stock Type R exhaust sitting in my garage waiting to go on the car.
If I was to do it all over again I would of picked up the RV6 catted downpipe/frontpipe combo I don't like the smell from the catless downpipe I was thinking it wouldn't be as bad as my 9thgen Si since I'm running 35% ethanol and the motor is way smaller but I was wrong.
