Q:what makes borla and all the other name brand exhaust systems so great? what justifies the cost of them costing over $500?how are they different from brand y on ebay for $100?

They have to pay for research and development somehow. The off brands are just knockoffs or copys of their product and are manufactured with cheaper/inferior materials.

Q:i just want a good exhaust system and a good cold air intake system for my car to get more power and mileage and just want to know which brands are good. I was looking at a Spyder cold air intake for $68.87.

There is no best. The exhaust systems are just a slightly bigger than stock piping with a different muffler for sound. So just pick one with the sound you like. A cold air intake is the same thing. It's just a couple feet of piping that pulls air from the fender and tricks the maf into thinking it its flowing more air than it does to lean out the mixture and make a little more power. It doesn't make a difference what the name on the pipe is or the color of it so just pick one and enjoy the 2 HP you may or may not get.

Q:why does a performance exhaust system increases power?

new limitations to reduce emissions(which DO NOT ACTUALLY AFFECT GLOBAL WARMING OR THE OZONE LAYER) make thier mufflers small and restrict air make them soft. a performance exhaust takes out all those limitations and makes the car exhale more easily so it can inhale more air faster/better. plus if done properly it makes the car sound good.

Q:I can get a kit for my truck for about 400 bucks, but can a muffler shop do the same thing for probably a little less?what are the benefits of a cat-back system?

Id definetly go to a muffler shop. they can weld it all up sound and safe. Also before you pick a shop look at other guys who have pipes and if you like how they look or sound ask what shop they got it done at and go there. You dont want cheap pipes youll regret it

Q:Tougou tank exhaust system throughput is not correct

Tiguan tank tank exhaust system throughput is not correct, there may be activated carbon irrigation problem! Is the air filter next to that!

Q:I have a honda, and my dad told me he was going to put a turbocharger on it, I‘m no wiz at cars, but is there some type of performance exhaust that I should put on my car?

A normal G35 takes 30 psi in both the front and rear tires If it is a G35 Sport it varies between 33-35 psi front and rear. Never Ever fill tires to the max pressure on the side. Vehicle Manufacturers engineer the the Tire Pressures for the vehicle to give the best traction, braking and fuel mileage for a vehicle. They did the math dont screw with it. Anyone who is in the TIRE INDUSTRY KNOWS THERE IS NO GENERIC PRESSURE FOR VEHICLES AND SETTING PRESSURES 5-10 LBS BELOW THE MAX IS NOT ACCEPTABLE AND SHOULD NOT BE GIVING MISINFORMATION.

Q:Since i want to gain some horse power, I‘m attempting to install exhaust system and cold air intake to my 2007 civic si coupe. But i‘m just worried if they harm my car‘s durability. I heard some stories that cold air intakes make some problem when its raining, because the water percolates through the intake to engine. And i‘m worried if installing new exhaust system does that kind of thing too. Is it okay to install those??

Exhaust virtually has no effect it is a percentage thing, you probably make 140 horse 3% increase is 4 horse if that, the cold air intake will gain about 5-8 horse on that type of car,so.is it really worth it?

Q:New to the car mods. I have a 2006 nissan altima. Should I buy just a muffler or a whole new exhaust system?

Hmmm. Depends on what you want out of the car and your budget. Putting an entire exhaust system can be pricey. If it's the sound you are going for I would just get a good muffler. Having a full exhaust system put in can give you a better sound, not much performanceactually if not any. Personally the first mod I would ALWAYS do is chipping, then engine work, then worry about the exhaust (unless engine work requires exhaust upgrade). You don't want to have a sweet sounding car and when you gun it that's all you getis sweet sound. If you still want an exhaust system, I love Borla exhaust.

Q:My exhaust system backfires. it consists of headers, pipes, and mufflers. i have been told that the back fire in the exhaust system (not the carb) would be caused by air in the pipes because of poor welds. i have also heard that an H pipe is the correct way of exhaust work, instead of two isolated straight pipes.is either reason right? aftermarket carb, bypassing emissions controls, ‘84 305 K5 Blazer.

I own a shop, and have seen this for years. This is caused by the engine sucking air into the exhaust system via a leak. It can usually be found that the gaskets where the headers mount to the heads are leaking, and when you let off the gas it sucks air into the pipes, and explodes the excess fuel that is left over in the pipes. Replace these gaskets, and keep the bolts tight as in check them every couple of weeks. This is one of the drawbacks to cheap headers, as the mounting flange is too thin, and the bolts won't stay tight. As for the H pipe, they work really well. They do help scavenge the exhaust out of the other side as one side fires. Use a piece of pipe, and blow an air hose over the end of the pipe, you can see it form a vacuum on the other end of the pipe enough to suck stuff up into the pipe. This was invented by NASCAR way back in the 60's, and they found a scavenging pipe would increase the horsepower. Also by exiting the pipes at the side of the vehicle the wind going down the side of the vehicle would cause the same effect, and created more horsepower than running them out the back straight. Some people will use a turn down on the ends to capture air flowing under the vehicle, but it's just not the same. One more thing; The backfire can and will sometimes burst the muffler, as I have seen it blow a huge hole in them right at the seams. Glad to help out, Good Luck!!!

Q:I have a 1995 Civic DX 4dr. and i ordered the exhaust thinking i could install it myself, but found out that I could really screw things up. How much on average would a shop charge me to just install it?

Older cars usually don't have ABS. If your car doesn't come with ABS, it isn't possible to install ABS afterward. The ABS just pulses the brakes for you. If your car doesn't have ABS and your car skids when you brake, just use your feet to physically pulse on the brakes (just step and lift your feet on the brakes lightly, that imitates the ABS system, of course not as well though).
