I have an 8th gen too, though mine is the deluxe. I'm not sure about best, but I got a fork cartridge kit from DMR suspensions, and the difference was night and day.

Looks great... I know I said no more mods to my bike, but now I'm considering this😂

On my 8th gen, (not so sure about the others, one would have to go back to the beginning of the thread to be sure) the O2 port is moved backward so one needs an extension harness/cable. Found mine here on amazon, if you do a search like I said above, you can find other retailers. I bought this because of 2 day shipping as my bike is already apart. https://www.amazon.com/gp/product/B074FFMD3R/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Thanks. A friend told me it was the for a Honda Civic but the ones I kept finding didn't seem to match. However, your post spurred me to check again and after trying many combinations of search parameters, I eventually stumbled on one I think is the right one. I'll know for sure when it arrives tomorrow. PS. The one that seems to match is for a "Honda Civic SI". Just searching for "Honda Civic Oxygen extension harness" will keep bringing up the wrong connectors.

Haha... I did read through from page one once... but now we are at 46 pages, and I'm sure most who did, forgot soon after😂. Its a easy fix though

So I've been to 3 different auto parts store in locally (Autozone, O'Reilly, Advanced Autoparts) and I can't find an extension harness for the O2 sensor. I've checked online and seen some, but I'm scared I'll get the one with the wrong adapter. Can someone who has done theirs point me in the right direction? P.S I have the 8th Gen. Thanks.

I have the 8th gen and a 2 brothers exhaust and mine wont fit either. Tried the OEM and it didnt fit too. I'm taking the mid pipe for the 2 brothers to a shop this morning to have it expanded so it can fit.

Got my headers a couple of weeks ago and finally got around to the install. Went well for the most part, but there a leak from the front exhaust pipes. Will need to figure that out. Love the way its turned out though. Looking forward to getting it on the road.

Page 11 of this thread talks about the gaskets. I followed those (and from discussions with a buddy) and ordered a set of 42mm washers from Delkevic. I got on the phone with them yesterday and they said they just had some come in. You might want to hurry up if you want that as they are almost always not in stock (this particular size, no idea why). Been checking for the past 2 weeks before I finally contacted them. https://delkevic.com/copper-gasket-42-mm/
