Bolt on great and can feel the hp increase in the higher rpms good quality product, however the s.s clamps it came with were to small i managed to get all but one to fit i just don't know why they would have clamps that barely wrap around the tubing

This went into my 2002 SPI Ford Focus and the idle became smoother with less hiccups. Power feels better at midband, and maybe a few hp improvement. Online videos show this product does remove some deposits from combustion chamber. It gave me the result I was expecting. I am happy to recommend the product from my own experience.

Worked just as advertised. Took me 5 minutes to install and I received a little over 3 mph speed boost (a little more down hill). Certainly worth the price they are asking. Would give it 5 stars if the speed boost was a little more. But, again, for the price this is a great upgrade.

Wow...  After this was installed, my Wrangler is quieter, but still has a nice growl. The power jump was impressive. I am still trying to compute the gas mileage, but it appears to have given me a boost there, also.  I'm almost afraid to replace any other part on my Jeep, because I fear that, by comparison, I may be let down.  If you have a Wrangler and are considering this upgrade, I have only one thing to say...  DO IT.

Installing New cats fixed the problem my truck was having at high RPM.  Above 3000 it would lose all power and make a clicking noise. Sometimes it would throw a bank 1 too lean engine code.  These did the trick and were not too hard to install with the help of a friend and a welder.  I installed these on a 2005 Ford F150 and did need to buy some extra length of pipe to get the proper fitup.

The truck sounds a little bit louder now too.  in my opinion the noise with the stock cats is a bit too muffled.  with these cats, it sounds a bit more like a V8.

Build quality is also very good. the metal thickness was heavier than I had expected.

I ordered this intake on monday and with prime shipping i received it on wednesday. The installation was vary easy provided you have access to a lift so u can put the car up in the air. The directions were step by step and did not leave many questions to be asked. If u buy this intake do not get a bypass valve for it, the installation instructions clearly state that the bypass valve will not work with this system. Also the bypass valve will disrupt the finely tuned air flow. You should definitely get a pre-filter since the air filter sits about 2-3 inches from the bottom of the bumper. On the first test drive the performance gains were noticeable immediately. The RPMs ran 200-300 lower at most speeds. Also the torque increase id awesome. The sound produced with this intake is not much louder than the stock intake when at idle and light smooth throttle. But when you open up the throttle the sound is amazing, you can hear the immediate woosh of the throttle opening up and the deep roar of the V2 intake. Finally this intake provides a much quicker throttle response.

Feels so much better than the stock flywheel in terms of how fast the engine changes speed; it revs up and down so much quicker, allowing for faster shifts. Installed in a 2003 Subaru Baja 2.5L non-turbo.

Great addition to upgrade performance and torque. Ensure you replace your thermostat and exhaust, if not use Stage 1.
This made a huge improvement to fuel and overall performance

First off let me say that i saved a lot of money buying this through Amazon. Took some time to install but when it was finished
i could hear the diffidence in the sound of the engine and when out on the road i felt the extra power the car gained.
Great product.

I got this sprocket in the mail and installed on my bike ~1 hour later.  The sprocket fit perfectly and I had no issued installing it...removing the stock sprocket was a different matter.  I could not get the bolt off the stock sprocket.  I grunted and groaned and it just wouldn't budge.  I broke out the impact wrench and it zipped right off.  At 6k rpm the speed has increased from 45mph to 50mph.  I haven't noticed a difference in acceleration.  The gears are a little wider so I'm not shifting as much as before.  Take off from a stop is not too different than with the stock sprocket.  Steep hills make you downshift if you're doing under 5k rpm.  60 mph is at 7k rpm.

Installing the Solo Performance High Flow Catalytic Converter on my 2007 Pontiac Solstice GXP was an excellent improvement. The exhaust note is deeper and "richer" sounding without being obtrusively loud (a critical concern of mine) and there is definitely more torque on tap by "seat of the pants."  I drive the car extensively during the summer, and I didn't want a really noisy exhaust. Those who do can install an aftermarket "cat-back" exhaust system or a "cat-delete" straight pipe (which is technically illegal). The Solo Cat is more expensive than some others on the market, but it also has a longer length catalytic element (5 inches as opposed to 3, supposedly).

I am a 65 year old Muscle car guy with an enthusiasm for big, high horsepower V-8s. When I listened to many youtube videos of modified aftermarket Pontiac Solstice GXP exhaust systems, I found that many of them had more of a raspy-rattly sound that I disliked. I'm glad I went with the Solo Cat.

For those who don't know, the stock GXP has a computerized "tune" that will supposedly reduce the power gained by the high flow cat unless a custom aftermarket upgraded "tune" is installed. I am in process of having a custom tune installed which should give me an even bigger performance increase.

Finally, let me say that my research on exhaust systems revealed that several performance enthusiasts on the Pontiac Solstice forum including current and/or former GM engineers say that the catalytic converter is the most restrictive component in the exhaust system and is the first and best exhaust modification to make if you want more power (in combination with an aftermarket tune). They also say that the rest of the exhaust system from the Cat back does NOT restrict horsepower until you get upwards of 360 to 400 horsepower (the stock rating is 260 horsepower, the stock exhaust pipe is a generous 2.5 inches in diameter for an engine that is only 121 cubic inches!), and so replacing the rest of the exhaust system is mainly "cosmetic" whether visual or sound wise until you seriously improve other parts of the power-plant. One more thing, since I installed the Cat, about two days later I got a "Check Engine" light, and the car is sometimes running rough. I believe this is because I have not yet installed the aftermarket "tune" I spoke of. I expect to update this review when I get everything sorted. Perhaps I should have given only four stars until I find out if the tune will resolve the issues, but I have some aftermarket charge pipe and air intake that are more likely the "culprits."

I love the intake and even on a 2.7L V6 dodge charger it sounds great once you hit 3k+ RMPs. Ive gotten compliments on it and people think that I am hiding a 5.8Hemi under the hood!

I have a 2013 scion xb and I love this thing. The deep note of the intake when you hit the pedal is what makes it worth it. It does also feel like it helped with the gas mileage. It does feel like it made my vehicle more responsive and has a quicker pick up. I just had a little bit of a headache when installing it following the instructions. I ended up taking the heat shield out to install two brackets then reinstall the heat shield which made it a whole lot easier.

Sounds much better than the stock air intake system and definitely increased horsepower.  This intake is also much lighter than the stock intake.

Alot of people say that they don't notice any gains in horsepower after adding this, but i certainly did!  This is my first engine mod of any kind so maybe that makes a difference idk, but all i can say is I have a hard time not slamming my foot down in gas to feel the boost of power!  The sound definitely doesnt help either!

On my sn95 mustang gt the jet performance chip made a noticeable difference .it's a awesome addition if your using aftermarket bolt ons like headers ,a intake, a shift kit, etc. A definate power enhancer.

Near doubled the HP on my 1978 F-150. Application was on a 4.9 litre (300 ci) straight six. The truck had the OEM stock log manifolds with a Carter YF 1 bbl carburetor. Very, very happy with the performance upgrade. My mileage has improved as well now that I can actually shift into 4th gear before 50 mph!
