That might be louder than I'm trying to go. I really liked the xforce sounds on the 350 in some of the other videos I've watched. To bad it doesn't fit....I wonder if I bought it, if I would be able to make something custom out of it.
I got the idea from a YouTube video and thought it sounded normal in the video, but it came out louder to me. So if you think it's loud from the clips it's definitely too loud for you. Those were all with either the roof down or window open btw. I'd talk to a good fabrication shop and see what they can do for you. Maybe adapt a sedan system to fit or build a whole new one that'll sound nice

I ended up doing the same with my IS-C. Kept the cats and from there I have added Magnaflow Tru-X Pipe, Vibrant Resonators, and did a Muffler delete. 2.5 inch pipping all the way. Sounds amazing. So much fun to drive with the tip down and love hitting the red line. It also makes some pops with out a tune too.

Since I've just recently signed up for State Farm's 'Drive Safe and Save' program, then making the exhaust sound do its thing would decimate my discount (which is $12.60 per month). $12.60 X 1 year = $151.20. Mileage would probably take a hit too. I use my motorcycle for the sound, the Lexus for the quiet.

Just saying.

So how will State Farm be able to hear your car, even through the OBD port?

Very confusing - the F-Sport is to be a direct fir for the 250c (?) but bringing up the part # and adding my vehicle specs: 2012 is250c site says it will NOT fit. Does anyone know a catback exhaust that will FIT my 2012 250C ?? Or must I find a muffler/exhaust fabricator to piece one together? Looking to enhance throaty sound and maybe grab a few h.p. while doing it. IF NO catback, I suppose I could forgo any chance of a few h.p. - but still help sound with an axleback IF one EXISTS for my car. Thanks so much.

I’ve searched for years and none exist. I ordered a mid pipe and it sounds so much better, it did eliminate 2 cats, so there’s a HP gain. It was a normal IS fitment and it fit no problem

PTR08-53100 is the F SPORT accessory performance exhaust for the 2010-2015 IS 250C and IS 350C, it will fit all IS C models, but again it's been discontinued for some time now.

I don't know about other options that may exist.

I went looking for exhaust systems for the 350C and only found one YT video of the Invidia Q300. Does anyone have this axel-back on their C? does it drone? For that price, I bet I could have my muffler shop fab me up something real nice. i don't want anything loud, any suggestions on mufflers or resonators that won't drone super loud a high speeds?

Thanks for the recommendation. Is this the one (https://invidia-exhausts.com.au/prod...pe-lexus-is250) you got? You kept everything else stock, exhaust wise?

Good deal, thanks! Do you feel it's less "drony". A better way to put it, is it loud inside the cab or with the top down at regular around town speeds?
