The muffler should actually give you "more" power, because it is less restrictive then the stock or dual chamber styles. Think of a motor as this: It's a big air pump. The more efficiently you can get air in, and out, the more power you will make. So, you will help the air (exhaust) get out easier.

The more efficiently you can get air in, and out, the more power you will make. So, you will help the air (exhaust) get out easier. Technically any altercation to any part of the car shouldn't pass inspection. Even a ford racing muffler on a ford car (my buddy has a setup like that thats why i mention it) shouldn't pass. As for emissions, it all depends on the car. My toyota could drive around with like no muffler at all and it would pass (not really but damn near). To op, if you want better gas mileage just maintain the car, give it a tune up, clean the injectors, add some fuel additives. Driving 100 miles a day, you WILL REGRET a loud exhaust.

MONTECARLO138 Posted May 4, 2010 Author Report Share Posted May 4, 2010 well from what i asked my mechanic yesterday he said as long as i dont mess with the cat i will pass inspection and i already have a thrush muffler on now but i want louder so thats why i went with the glasspack and half the time i cant here the engine whenever the bass lines come in so, and had a tune up a few weeks ago then something in my ignition was shorting out my coils so replaced the same coil twice till they realized what was burning them out and thanks for all the help hopefully ill get to put it on this Saturday if im off work Quote Link to comment Share on other sites More sharing options...
EclipseChris Posted May 5, 2010 Report Share Posted May 5, 2010 You will pass inspection, i tried to stress the word "technically". But do whatever you wanna do its your car Just gatta ask... why bass and exhaust? I bet it doesn't sound as good as it could. Quote i resolve to be a nicer moderator. Tercel build R.I.P.

MONTECARLO138 Posted May 5, 2010 Author Report Share Posted May 5, 2010 i like bass and when im not listening to the radio i still like to hear something loud and don't really have anything performance wise to my car except cold air intake so and the glass pack was going on my friends truck but he decided to do a full straight pipe with i believe edelbrock header or something like that so free muffler why not use it rite?
