no muffler?

[00ls1TAWs6]

so i just got my trans am about 2 months ago and ive noticed that it doesn't have any type of muffler, i was wondering if this is bad for performance or gas mileage

[0rion]

no, it'll be fine. I ran with an open cutout for a couple years.

[00ls1TAWs6]

ok, but ive been getting like 16 or 17 mpg, you don't think that has anything to do with having no muffler?

[0rion]

if anything your mileage should probably go up a little bit. I would look elsewhere. Is the car running funny at all? How heavy is your foot?

[00ls1TAWs6]

well i get on it every once in a while, but i drive 15 miles to school everyday and i usally keep my foot off the gas then..it seems to be running right ever since i got the maf replaced

[0rion]

how many miles on the car and has a tune up been done? So the mileage is still bad after a new maf? What about O2 sensors, how many miles on those?

[TransAm11973]

no offense but how did you not notice that the muffler was missing, I took my muffler etc off a few months ago for a bit and the thing sounded like a damn jet. Was kinda too loud for me and I love loud deep exhausts

it has pipe all the way back like it was proffesionally done, just with no muffler

it has 69000 miles, and i just replaced the front o2s a month ago

so is it okay to remove the muffler on my 99 z and just leave the over axle pipe with nothing more? i bought a magnaflow, but the tip on mine are too small to even make contact with the magna, besides i love the way it sounds without the muffler...ive been told it could hurt my exhaust valves, but it wasnt likely. What do you think? I dont want to risk damage for the sound, but dam it sounds good...Thanks

Have you checked if the air filter looks like you vacuumed last night's party?

[red99ws6]

ive ran a few different vehicles without any mufflers for long periods of time without any issues

[Speedy_Gonzales]

make sure all your tire pressure is normal and cleaning your MAF will help your mpg

like i said above, i replaced the maf a month ago and i checked all of the tires too

it seems to look clean, i don't know the last time it was replaced...i figured with a manual i should be getting better than 17 or 18 mpg

Are you talkin city or highway mileage?

[00ls1TAWs6]

Are you talkin city or highway mileage?

A little of both, during school i drove 30 highway miles each day, i don't drive very much in the city

Like how many highway vs. city miles. I drive over 90 highway miles a day and can get about 26-28 on the highway. In town I am lucky to get 15.

[bryceslu]

thats not unusually low for mixed driving...it all depends how heavy of a foot you have.
I get as much as 32 highway around 18 mixed and as low as 9 around town.
