Hey everyone i have a 2 1/2 inch cat back exhaust with a lukey muffler im just wondering how much better, louder/performance/econmy wise another 2 1/2 inch pipe coming out from the other side would make. and also how much round abouts this would cost?
on the red back exaust site it said that there 2 1/2 system with a high flow cat could increase the cars power up 15% pedending on the car.. that was for a vn/vp exaust so yer and sound wise i gues it would sound betta
mines lukey but im guessing itd be the same, any other input from people? im also looking at price if it doesent cost to much id look into doing this soon. i got my 2 1/2 inch exhaust form profix for $250 originally i knocked it down $50
To actually answer the question....another 2 1/2" pipe on the other side will make it a sh**load louder but also make it lose a sh**load of power. It wouldn't pull a tampon out of a hooker. Don't do it unless all you're after is noise and a defect notice.
something to do with slower air speed or something not sure. i dont think you would lose any top end or much, just a lot of low end power but not sure.(i am sure my exhaust is too big for my car but it still gained power)
well thats depressing cause it would look sweet as!, *hopes soem one comes along as says it doesent lose power* hehe
I'll tell you it wont loose power maybe a touch off idle, but really no and it will be quieter (obviously since you will have an extra muffler) the only problem is unless you run straight gas and have the fuel tank removed you can't really run the second pipe out the other side without some crazy bends around the fuel tank behind the rear bar. The V6 doesn't make enough power to really benifit from a really good exhaust system anyway but at least you know it's there incase you ever do come across another 50 rwkw somewhere
You will lose back pressure which gives you your low rev torque. In effect you are going to run a 2 1/2" exhaust on a 1.9 ltr 3 cylinder. To have a power increase you need to increase the velocity of the exhaust not the volume. Try dropping the pipes off the manifolds and driving it. That is what the power will feel like. Fuel consumption will be increased as well. Also I will add that and engine does not produce power, it produces torque. When an engine rotates, it is the ability to turn a device attached to the engine, this requires torque. The heavier the device it has to turn, or the more resistance it meets the higher the torque that is required. The energy produced by this is measured in kilowatts, the faster it can get to maximum revs, and the less resistance it meets the higher the kilowatt output. People talk in kilowatts because it sounds better than saying 'My car has 140 Nm of torque'. To achieve the desired torque level, you need to have an exhaust system that flows freely enough to rev high but also has enough back pressure as to not sacrifice torque. It is a fine balance and every engine is different. Go to a mechanic and ask for a performance exhaust, his opinion will be different to an experienced exhaust specialist.
