tornado_735 Posted December 17, 2009 Report Share Posted December 17, 2009 I recently got bored, and decided to see what kind of a change I could make to the sound of my exhaust. I cut the OEM muffler off, and replaced it with a cherry bomb glasspack. So far, I am satisfied with the change in the sound of the exhaust. It is definitely more pronounced, but it's not really intrusive. Well, there are two things I am noticing. First, it seems as though my engine gains revs a little more freely. I will not equate this to a gain in power, it just seems as though the engine breathes a little easier. Is this a possible side effect with removal of the stock muffler, or am I just imagining things? Is it being able to breathe more freely coming at the cost of reduced back pressure? Another thing I am noticing is that when I rev the engine with it sitting in park, it will nearly stall before returning to a normal idle. This only happened once before like 3 months ago. It does it just about every other time I rev the engine while stopped now that I chopped the stock muffler off. Could a loss of back pressure cause that? Thanks!

RobertISaar Posted December 17, 2009 Report Share Posted December 17, 2009 "ability to breath" is directly correlated to horsepower.... or torque technically, but you have more of it now... it MAY be related since it used to do it to me when i was still running OBD1.5, but i was able to tune it out to get back to a normal idle with my 9396... try an idle relarn and it may not fall down as far.

tornado_735 Posted December 17, 2009 Author Report Share Posted December 17, 2009 "ability to breath" is directly correlated to horsepower.... or torque technically, but you have more of it now... You know, you are right; and I found it out quite by accident. I took my girlfriend to work today. I was waiting to turn left, and there was a small opening between two cars that I could make, I was just going to have to step on it. I stood on it, and where I would have just gotten a chirp before, I squalled the hell out of the left tire. It caught me by total surprise. When I got to an open road near home, I stopped, then put it to the floor. Again, where I would have maybe gotten a chirp before, I am able to spin both front tires over. So I venture it safe to say I gained a very little bit of something. Quote Link to comment Share on other sites More sharing options...

It's weird that about an hours worth of work resulted in such a gain, even if it is a small one. Quote Link to comment Share on other sites More sharing options...
BXX Posted December 18, 2009 Report Share Posted December 18, 2009 FWD cars with equal length halfshafts (such as ours) with a good 100% proper alignment, even tires and pressure, will not torque steer. Quote Link to comment Share on other sites More sharing options...

Yup, or craptastic control arm bushings that allow the car to toe out under hard accel or old soft cradle bushings that cause the cradle to float around under the same hard accel.
