Q:Listing says Brand New TOP SPEED PRO-1 Dual Catback Exhaust System in Polished Stainless Steel with TIG Welding with 100mm Tips / 60mm Piping - Under 97db sound level with Silencers (Silencers Included) / No C.A.R.B Exempt for California Customers.What does No C.A.R.B Exempt for California Customers mean? I live in California BTW lol

The pictured system does not include a catalytic converter. Unless a converter is located on the engine pipe (upstream of the long pipe shown) installing this exhaust system would eliminate the converter. Converters oxidize unburned hydrocarbons and convert CO to CO? thereby improving air quality. The pictured exhaust system would not meet emission standards in many other States as well. (CARB is California Air Resources Board). The pictured system will not improve engine performance, (the splitter is too far from the outlet) but will attract Police attention due to excess noise. If changing your exhaust note is the objective, you can simply replace the existing muffler. If this is unclear, update your question. Please choose a best answer from among those you get.

Q:I have a 2006 chevy silverado 5.3 (78in) and am in the market for a kickass exhaust system. I like to do a lot of research before I buy anything big like that so does anyone know where I could find some reviews of exhaust systems (borla, magnaflow, etc.)? I‘ve looked through a couple of my magazines but I don‘t have much. Any help would be great.Suggestions would be nice too! Looking for something with deep deep sound.

I wouldnt listen to some of this advice Especially not from someone who has never even owned a mudder and is simply going off second hand knowledge and online vehicle reviews, first off id stay away from foreign trucks iv hauled my fair share of them out of the mud and they are built like **** and hard to modify, go domestic, personally i think dodge is garbage but thats just my opinion chev and ford are both good, id go with something old and inexpensive, early 90's and late 80's are reliable well made trucks but if you want something even easier to mod go with late 70's carborated, they are not as reliable as fuel injection but are very simplistic. If you are deadset on an suv blazers broncos and pre 1996 jeep grand cherokees are all beauties. Once you have on of these id go 6 inch lift and 38 or 40 inch tires. Make sure you have selectible lockers on front and rear, this is very important. If you like hill climbing make sure you got a reg cab and shortbox for clearance. If you can weld put some rock scrapers to protect your rockers and a front winch can get you out of some tricky situations forsure. My best mudder was a 1978 f150 with a big block carburated v8. So dont listen to anyone who says you should go new because for the most part the newer you go the more expensive and harder to modify it gets, save yourself the trouble and go early 90's or older

Q:I have a Kawasaki ZX10R 2009 and i ride it without exhaust and i want to know if it is in some matter bad for the bike and is it better or worse for the performance? What is the difference between a open racing exhaust and just removing the exhaust? Thank you in advance.

There are two types of exhausts that people use in drag racing. 1. Open exhaust. 2. Tuned exhaust. No exhaust will actually hurt performance. It all has to do with the exhaust pulse. As the exhaust gases are exiting an open exhaust they will cause a vacuum. At the moment the exhaust pulse is exiting, the exhaust valve needs to opening. The exiting pulse will then help pull the exhaust out of the cylinder, assisting in the exhaust cycle. All professional drag racers use tuned open exhaust. Open exhaust just means there are no restrictions in the exhaust system, such as a muffler or a cat. Tuned exhaust means that it is set up so that the exhaust pulses are timed correctly. No exhaust means you have NO exhaust pipes at all. You will lose horsepower with no exhaust, because there is NO exhaust savaging due to the exhaust pulse.

Q:i just dont know what the best ones are. many people have suggested the flowmaster T 40. any thoughts?

Maybe. You *must* check with your dealer to make sure. Or you could actually put in your question the make/model of bike.

Q:I have a 2005 f150 and want to cut my cats off , what would be a really loud exhaust , and also would cutting the cats turn on my check engine light? And how do I get it off someone told me like orielys or autozone could get it to turn off. Thanks

If you remove the cats you won't be able to pass a visual inspection to get a sticker, and there is a pretty hefty fine if you are caught running without one. You can go cat-less, but you will need MIL eliminators to keep the check engine light from coming on, they are plug and play, they plug into your O2 sensor plugs. Try SLP Loudmouth II exhaust, that's a pretty aggressive sounding exhaust.

Q:Years parts are interchangeable?

Increases power and MPG'sfirst guy has no idea what he's talking about.

Q:What is the best sounding exhaust system for a ford f150 2010 5.4l?

Magnaflow or Flowmaster. Make sure it is a Header-back. Meaning, the exhaust goes from your engine and out. Most exhausts are cat-back, meaning they go from your catalytic converter and back. They only sound loud and thats it. With a header back, the exhaust leaving your engine has more room to flow, and it will flow faster, you will also have a newer, better, catalytic converter. Ergo, you get a much better exhaust system that cleans your engine, is LOUD, and gives you some gains in horsepower.

Q:i want to put a aftermarket exhaust system on my car but is it illegal in san francisco, california? and do the chp pick on cars that look jdm more??

First off, putting an exhaust on your car doesnt make it JDM. JDM Japanese Domestic Market ie: Cars made in Japan. Now to answer your question: Exhaust Systems: Whistle-Tip Prohibition 27150.3. (a) A person may not modify the exhaust system of a motor vehicle with a whistle-tip. Modification of Exhaust Systems: Sound Level in Compliance 27151. (a) No person shall modify the exhaust system of a motor vehicle in a manner which will amplify or increase the noise emitted by the motor of the vehicle so that the vehicle is not in compliance with the provisions of Section 27150 or exceeds the noise limits established for the type of vehicle in Article 2.5 (commencing with Section 27200). No person shall operate a motor vehicle with an exhaust system so modified. (b) For the purposes of exhaust systems installed on motor vehicles with a manufacturer's gross vehicle weight rating of less than 6,000 pounds, other than motorcycles, a sound level of 95 dbA or less, when tested in accordance with Society of Automotive Engineers Standard J1169 May 1998, complies with this section. Motor vehicle exhaust systems or parts thereof include, but are not limited to, nonoriginal exhaust equipment. This was pulled directly from the California Vehicle Code which you can find here www.dmv.ca /pubs/vctop/vcpdf/d. if you have any further concerns. There are also other statutes regarding the catalytic converter, but that isnt California law, it is CARB law. Your vehicle must have a catalytic converter with a functioning O2 sensor attached. Thats it, keep it under 95 decibels, no whistle tip and have a functioning catalytic converter.

Q:if i were to just get a new a muffler and exhaust tip rather than spending well over 500 dollars on a nismo exhaust system what would be the main differences seeing that i would get a flowmaster muffler and a borla cover whats the difference in comparison to the complete nismo exhaust system

You can get used oil at the local recycle center special for porche's and you should consider a ford as they do not require additives
