Hello New and have been busy with my 4afe geo prizm
Well today and this is interesting because i didnt realize what this would improve or make worse. Put it this way with this little car i was afraid to merge onto the freeway just trying to get to speed and having a big rig breathing down your neck. Well no more.
Ive been building V-8s for quite some time and yes a muffler can make a decent noticeable gain not a lot but some depending if you got the right one for your vehicle. I have never dealt with 4 cyl performance but I recently purchased a 96 Geo Prizm with a 1.6L DOHC for commuting for 600 bucks everything worked even the ac. It seemed weak even for a standard and really quiet and smooth does not come with a Tach either and yes i can feel when its time to change gears, however i wanted a little sound not a lot and this 3a muffler was the only one on the shelf and i wasnt waiting in line again for someone to go and get a different one for me and core back for the starter i only added 23 bucks and was out the door. I came home cut the stock one off and put on the new one. It sounded great not loud and abnoxious or tin can but nice. i went for a drive and got a huge surprise. for instance the car at cruising 70 mph the rpms sounded a little high like 4000 or so. well anyways with the free flow muffler on this car it was like adding 50 to 75 HP to a V8. It ran fast which kinda amazed me now i kinda understand that a little HP in a tuner goes a long way it even gave me longer rpms through each gear got up to 90 and the RPMS were lower then with the stock at 70mph. It just pulled alot harder. And just because its louder doesnt make it faster. In my opinion i dont think that adding headers or high flow cats would add much more HP then just the muffler did. Nor have i ever seen headers or straight pipe help 4 cyl or 6 cyl HP talking. In fact a lot of times you loose HP due to loss of some back pressure. anyways i left the cat and resognator on there and worked wonders I might actually tinker with it a little bit and see how fast i can make it.
In the past month i have put on a starter, battery, alternator, belts, tint, and painted the wheels and added a little lucus with the new oil. The car was not well taken care of by the previous owner. All not really a big deal and now trust the car to go anywhere plus the gas mileage is great. I have a supped f150 with 351 windsor that i was commuting 60 miles a day ouch for gas. I also have a ford taurus with 3.0 which made me work on the side engine to begin with wifes car so no choice still dont like them but learning that taking off most of the engine to replace a piece isnt so bad. You know i have more room all around in the Geo than i have in the taurus.
All in all ive been happy with my little 600 dollar car i want to say it is only the 4th import i have owned in my life have and had a lot of friends with them and helped them here and there. Im a Ford muscle guy mainly but older chevy, dodge muscle before 70s is good to.
