I want to have an exhaust system like my boyfriends firebird trans am 2000 cat-back exhaust system. But is that possible with a four cylinder? I have seen a celica with dual exhaust on cardomain.com but would it affect my fuel economy more than 10 mpg or would it sound terrible or would it mess up my engine and what not...? Thanks...

Yes you can do it... Will it affect your performance? Yes... you will lose back pressure... and this is coming from personal experience... If you don't have any plans on up'ing your power above 150+, then I'd recommend that you stick with a single muffler setup. |

Thanks Kuya1284 and Dazzzza, but what did Kuya1284 mean by back pressure? I don't want to ask my boyfriend stuff he thinks I should know and that sounds like I should know what it means, but can yal re-enlighten me again, please.
Dazzzza and anyone else with the dual exhaust, is it worth it if I only plan on putting in a drop in K&N air filter and where might I get the dual exhaust from, because its not like the Firebird, you can't go to any random website and get it, right? So that was a run on sentence, but I tried...

http://www.6gc.net/forums/index.php?showto...=2228&st=20&hl= Read my last post about back pressure loss and power... Not quite clear...but it's something like that. It'll give ya a relative idea. If you want to go dual for performance...don't bother. Not worth it. If for looks, sure. Knock yourself out. Just do it with smaller piping...say 2" or so. If you do justa single catback... don't go larger than 2.25" or so. Many will say 2.5" but that's very big for an n/a 4 banger. |

would a "Y" pipe in 2.25" work with out depleating back pressure? then you would get the best of both worlds, looks and function. can you even route a Y pipe under the celica?
DB I didnt read your link...oops By Y I mean pretty much all the way back... basically one step further then just welding on a second exhaust tip... This post has been edited by DustyBurns30: Aug 20, 2003 - 11:13 PM |

Hay thanks for the info...!
I have another little question which would be better getting a dual outlet single muffler or getting two mufflers with single or dual outlets? Does it make it sound any better and will it affect my back pressure dramatically? Thanks yal... |

I have a single muffler with dual outlets. (dual canisters) It's basically two small canister mufflers fitted together. the only difference is it's a tad quieter than a single outlet.

No, it won't sound any better... Yes, it WILL affect your back pressure, especially more so since you have an ST. DustyBurns30: Yes, a Y setup is how this works... If you guys don't care too much about loss in performance (since these economy motors don't have much to begin with), then go for it. You won't gain much, but you won't lose much either... The dual setup is mostly for looks for our cars... |

Hay thanks guys... and now do any body have any particular type or brand of muffler that I should buy... On firebirds, Flowmaster and Magnaflow are the two best, so does that apply to the celica st.

i got a custom magnaflow system. I'm plannin on upgrading to duallies when i go turbo. looks and sounds great. im pretty sure that if something is a good product and it is universal, then its good universally. But yea, the dual exhaust is kind of ridiculous on an un-modded I4, but hey, whatever floats your boat. or gets rid of your fumes.
and one word to the wise, if you plan on getting a bodykit and you have a dual exhaust you are gonna need to have your rear bumper modified, cuz all the bodykit rear bumpers (except carcept) are made for single exhaust.

Get a Veliside teardrop from optionsauto.com
If I could go back, I'd get it. Jon |
