I have a 97 RS with the 3800 series ii....I just use it as my economy car to get good gas mileage....I just bought it and I havent really checked the mileage yet but so far Im just below 3/4 of a tank and have already driven 200 miles...I drive it to and from work about 50/50 highway and street...its completely stock...so my question is..will a cold air kit give me better gas mileage or cause me to get worse with the only benefit being better throttle response and a little more HP...I dont want to ruin a good thing...

also what about a flow master? same question...will it help with the mileage or make it worse? I just cant stand that chessy *** 1 exhaust pipe sticking down...I wanna put the SS tips on it to make it look a little better...what will it sound like?

I use to just do mods for more power and not care but thats what my IROC is for...Im just trying to get better mileage out of my 97

I dont know much about the V6's ....Im in the process of putting in a 383 in my IROC...

thanks

I know I can do a chip and all kinds of stuff to the V6 but its just not a street racer type engine.....once I get my super rammed 383 on the road...then the fun begins!

 

cold air kit = better gas mileage? slightly. flowmaster... please dont'...

 

Just to clarify. did you mean you only used a little over 1/4 tank of gas and went 200 miles. or did you mean you have used a little over 3/4 tank of gas to go 200 miles. If it is the first one. then that is crazy lol. CAI might increase it by like 1-3mpg. maybe.. flowmaster no.. bad lol. I would go hooker or the like.

 

flowmaster hurts gas milage?

 

yes a cai will imrove mileage, but will also give you a heavier foot most likely, same with an exhaust.

Basically the more unrestrictive your intake and exhaust are the better mileage you will get, "considering your keeping the internals stock"

 

No but it sounds like ****.

 

that was what i was thinking lol. just didnt' type it out lol

 

i like the sound
ill get a sound clip when i get home

 

I sincerely hope you have the 2.5" if you like the sound.

 

http://store.summitracing.com/partde...0&autoview=sku that is the one i got, i havnt heard it from out side the car yet other than idle but it seems to sound good

 

exactly, wait till you get into the rpms

 

i cant hear it from inside the car, people have said it sounds good but they have fart cans on theres cars so i dont know what to think. i have a video but the pipe is rattling cuz im missing one clamp but other than that the audio is very bad its just from my point and shoot camera

i wasnt joking, this video sucks
i just watched it again and i really need to fix that pipe, but untill then this is all i have, here is what was there

 

i have an american thunder cat back in my 99 firebird and once i took the reso off, it sounds great, throaty and loud...inside and out, i get compliments all the time

 

did you just replace it with pipe or block off the hole?

 

Man, your exhaust is freakin quiet. this is mine http://www.youtube.com/watch?v=dfkOr_rOg4s and this was it when i had loudmouth :-p http://www.youtube.com/watch?v=wyFT2rO5ddg I wish I has a video of when I had edelbrock because it sounded the best by far.
