Do we know any horsepower improvements from just the HKS midpipe? Also, where can I get the HKS midpipe?

 

It removes 2 cats, right? There will be some gains there for sure.

 

All the info you need here. https://www.clublexus.com/forums/is-...cs-inside.html

 

I thought I read somewhere that the HKS midpipe could be purchased for under $1000.

 

You can. google HKS P/N 33004-BT001

Not sure if there is anything in stock in US though. Let me know what you find. I just ordered the full catback exhaust system last week.

 

^^^ Where and how much if you dont mind me asking ???

 

Bought mine through a local shop with installation and dyno pulls for < $2600.

 

^^^ Oh ok, I think i remember reading a thread where you them mentioned this and that you also bought the last known one in stock in the US... sweet! wheres the pics and vids at bro? post them up for others to admire im sure the OP wouldnt mind

 

Yep that would be me! I will get the pics and vids (and dynos) up as soon as I can schedule a day to get them on. I'm hoping thurs or Friday. Still have not received notice that the exhaust has come in yet... Stay tuned.

 

I found one on auto tuning store for $877. This sounds mighty tempting. I guess you still need the oxygen sensor removing tool to install just the midpipe. Is that prolly the most difficult part of the install? (I'm wondering if I could do it by myself with two jack stands and a floor jack.)

^ I've seen people pick up the Borla full systems for about that price. Go big or go home j/k

 

IS350atWOT - You can DIY but I personally had a lot of trouble with my O2 sensors. With just jack stands I had loads of trouble getting enough leverage to loosen the sensors. I loosened them with spray lube and thought I had a great angle but I couldn't budge one of them at all and had to go to a shop (you really don't want to damage them). For the $75 it then cost me to have the full cat-back installed, I wouldn't have bothered trying it myself and would have saved a couple hours. But this was on an 08 w/ 60k miles with those never have been touched before. With a '10 you shouldn't have such issues.

 

I think I might ask the dealer how much they'll do it for the next time I'm in. That sounds like quite a chore.

I like the idea of this HKS mid-pipe over a full cat-back like Borla basically because I've had HKS before on my previous IS-350. I really liked the quality and sound.

 

Just to confirm, the HKS midpipe is what I have circled?
