Muffler Delete
The guy i bought my camaro from says it has a flowmaster on it and it sounds ok but i want it to sound more agressive so i was thinking about cutting the muffler off and welding a pipe in place...would this cause a loss in power or would it still be the same because it would still have the same scavenging...i want it to sound better but not if im gonna lose power...can anybody help me out? I appreciate any advice...thanks :)

It will sound pretty sweet. I was running my car for about a week with pretty much open headers and it sounded awesome! It was a little bit loud though in the car. Also, without enough back pressure it can hurt your valves, not sure why, but have heard it from many people.

backpressure won't hurt anything the less the better. having your camaro straight piped might sound bad *** at first but honestly it sounds like crap. i would put a catback system on it and get that nice deep sound.
|
Well i need the money for other things so i cant get a catback or else i would...plus i like the sound of straight pipes and its cheap...but i have heard that less back pressure equals less power...i dont know what to do

Sorry, but that's how bad myths get passed around. What you are probably meaning to refer to is how flow velocity of the pipes can affect performance. And what JordanT was saying about the valves could happen if an engine's air/fuel mix isn't compensated for after a free-flowing exhaust is installed...Exhaust Back pressure |

could you explain a little more about this . |
im pretty sure what camaro 69 was saying is that it is better to have a more free flowing exhaust as long as you re-adjust your air/fuel mixture after you install it...

whats a good air/fuel for a free flowing no cat exhaust ? an for a straight header pipe exhaust ,i've just order the xpipe with cutouts an i'm running headers no cats an most likely flowmasters . should the tune be richer or leaner for less restricted exhaust? |
You will need to go richer. Too lean will cause problems and a lot of popping on decel

i ran my car without a muffler for 7 months with no ill effects of it. it had more power in all situations, from idle to 5k. it sounded awesome, and wasnt so loud that it became annoying. i bought the pipe on ebay, just look up camaro muffler eliminator. its like $50. the best was the crackle it made on decel, it would make kids scream and cattle run
