I fitted an X Force to my 2008 isf. Dyno ran before and after. Standard front manifolds and picked up 16hp through the mid range and also an associated torque rise. The second run was a very hot day so 20 hp increase would be accurate. Rolling road dyno. Sound is good balance not to loud in the car. Highly recommend.
Great content, love your channel. I was slightly dismayed that you have perpetuated the myth that the factory exhaust tips are "fake". This is a very common mistake but these tips are actually specifically designed to collect air and mix with the exhaust gas. The tips are aligned with the output ports of the muffler and mounted in a heat dissipating frame. The back side is contoured for collecting air and mixing with the exhaust for cooling to avoid melting the bumper under extended high rpm driving. Keep the great content coming, you're a natural at this. I've subscribed.
I have the x force exhaust in my 2011 is350 and it sounds so awesome. I think it feels noticeably faster with it probably because the stock exhaust system has 3 mufflers on it which might be holding back some of the horsepower and sounds from the amazing engine in it
Got my Joe Z put on a couple months ago, I think the 8 speed trans helps a lot with drone as I really don't have much at all on the highway and I'm loving it. O2 sensors seem to be a consistent pain in the ass on our cars

A lot of ISFs are changing hands on market within past few months. I recently acquired a USB 11' with xforce already on it few weeks ago. Drone is mild and tolerable. One thing that'll certainly reduce drone is having sound completely exit out the back via fully piping the rest of the exhaust to the faux tips so that the exhaust/sound fully exits where the tips are few mm past the bumper. This was tested first hand on my s2000 where the single exit was slightly behind the bumper and I had it pushed out a few inches that resulted in a noticeable drone reduction. Most ISF exhaust is ending right behind the bumper which will have sound waves travel back through the car. Not saying you mind the drone but for anyone interested in reading this maybe would help. Helmholtz and quarterwave cans are different thing for another day. Another thing I wanted to do was delete the muffler on one side and hear what that sounds like. Half as loud as double muffler delete of course maybe less overbearing. If you somehow decide to do this let me hear it haha. Deleting the muffler and having a delete that pipes the same distance/out the back will be much different. Team Xforce is literally going to be a ton of ISFs lol...
Get the Xforce Varex. It’s valved and even with catless headers with I have no drone and plenty of power valves closed and it screams when I want it. Watch the video on my channel.
GrandMasta Grimm or get one with actual good parts. I have full headers and catback and it’s valved so only loud when I want it. When it’s closed it’s stock quiet yet still more power.
Just installed mine, sounds way better than stock . Videos are never going to do any exhaust justice! I’m gonna muffler delete with true quad tips . Should sound beefier. I’ll post on my channel soon .
My one thing of advice would be to remove the o2 sensors FIRST and not have half the front end mid pipe "hanging" from the o2 sensor wires.... I cringed when I saw that. Plus it's way easier to apply force when the mid pipe is still attached and not having to worry about the pipe moving like it was in your video when you were applying force to the o2 sensors... I just did an exhaust on my RCF and also a buddies RCF over the weekend.
@@CheaperEngineer There is only one belt and one belt tensioner, so if those correlate, then yes. Dayco is the OE of the tensioner assembly. I initially replaced only the belt with a Gates RPM. That fixed it for about two weeks. Slapped on the tensioner recently, so far so good. My F is a '14 with the latest tensioner assembly. It has been squeaking for ages.
If the exhaust is touching the cross bar this means your engine mount is gone. Get it replaced. I had this same problem. I changed my mounts when I installed the PPE headers
I have a 2015 RCF. Got an RR racing exhaust. Those o2 sensors were insane. It was an hour or more process once I got the socket and figuring out how not to break them. Also I did this all on jack stands and ramps while laying on my back. I do not advise that haha

ISF is miles better overall, but as a fun weekend car I would go STI or Evo. They're manual and I would say maybe a little more raw and fun. I wouldn't want to daily either of those, but as a weekend car they would be great.
Hey bro, I have v8 Lexus 600hl, just checking if you have any idea about catalytic converters? On One of the bank my catalytic converter is burgered and throwing engine check light on dash. Is it ok to drive car like that? Or what shall I do? I am in a country where cat is super expensive and I don’t wish to instal new one. Shall I delete the cats? Will car engine have no issues? Can I drive it like that?
Eventhough both the isf and mustang gt has a 5.0 v8 engine, it always sounds too muffled on video and nowhere near as good as a mustang GT or most american V8? Is it just that on video or it's like that too in-person?
The ISF does tend to sound less raucous than the Mustangs despite having the same displacement. The ISF sounds a little "cleaner" to my ears. Might come down to the different firing order they have..
Do you have any fitment issue? I have to cut half inch of the tip since its hitting on the stock exhaust tips and now i heard some metal grinding sound when i hit potholes and i found out that its still hitting on the stock exhaust tips again. Did u tighten those exhaust hangers to the muffler before u install?
My understanding is worn engine and trans bushings may affect the fitment of the exhaust. I kept things loose during install and then tightened down. I did have to do a lot of tweaking but didn't have any metal grinding sounds.
Lucky I have the same silver o2 sensor. Worked for me first go. Lol. My chassis brace also fouled on the exhaust. I ended up heating the bar and bending it a bit down for some clearance. I heard it might be due to engine mounts sagging, so maybe something to look at. I haven't bothered as yet. RR Racing also do upgraded engine mounts... Maybe an upcoming video? Hahaha
How much did you have to bend the brace to get enough clearance so your exhaust wouldn't touch? I have the same issue with mine and it constantly rattles. I've tried repositioning the exhaust a couple times and it always ends up just resting back on the bar. I'll have to look into your suggestion of the engine mounts sagging.
th-cam.com/video/lchhkmIcosY/w-d-xo.html That's as close as it will get. Full titanium equal length headers, and titanium cat back. Kinda has that high pitch LFA/F1 car sound. This is a $13k exhaust system 😅
Nick Adkins as you mentioned , its kinda have that high pitch sound. But nope, still the LFA sound crazy 😍😍😍. I wish I can understand whats the secret of that high pitched sound
@Anita Ayon The eventual failure? Yeah that kinda scares me myself, got it at 118k and currently 124k. Repaired touch screen and subwoofer myself, otherwise issue free. The actuator and starter are the risks for it. Solid otherwise.
I can't get on board with the American fascination with muffler deletes. Its so incredibly antisocial. I was on holidays there last year and the volume off so many cars was obnoxious to the point that cars don't even sound special anymore.
@Streamlined Stock muffler delete sounds shitty compared to X Force muffler delete. Just like at the exhaust differences they’re so different. The X Force is true dual, is less restrictive, and no cats. Mines sounded like the LC 500. Gorgeous exhaust system (with mufflers deleted). Stock X Force sounds 15% louder than stock.

Come on man. You're making the ISF crowd look bad. A true car guy mods a car because it looks, sounds, performs better. Not because it is the cheapest (first your aero and now the exhaust). Do some research like true car guys. Talk to other owners, see or hear their setups and then make a decision to your taste.

My xforce is super quiet on my ISF. No cabin noise, no cats, headers and I can't tell if my valves are open unless I stop the car and rev
Bought my ISF earlier this year and it came with an exhaust. Too loud and drones on the highway. Went back to stock and its loud enough for me.
Fortunately these things make awesome intake noises. But I get it, everyone has different preferences on exhaust noise.
