thanks so much... anyone seeing a problem with taking a stock LS exhaust system from a coupe and putting it on a sedan? both 2.2 of course.

Clmbngfrk18

ecoteched

i've read its 1.75...

IonNinja

2.25" is not the stock exhaust size

it wouldn't make sense to replace a stock 2.25" system with an aftermarket 2.25" one would it?

Clmbngfrk18

no it wouldnt but has any one gotten a stock system off w\out cutting it???

IonNinja

if you have access to a lift its possible but you really have to push up on the car to get it out...without a lift I see it being pretty damn difficult.

Clmbngfrk18

what do you push up on the car?? i have mine up on jack stands and the rear axle dropped as far as i can and need to go a little more

ecoteched

i put my car on a lift, took the old exhaust off and matched my magnaflow to it and they were the same size

Depends on whether the restriction is in the size of the pipe, the design of the exhaust, or the muffler....

ecoteched

resonator is a lot diff and better flowing and the exhaust is also less ristrictive

IonNinja

when i was watching the guy at the exhaust shop do mine he pushed up on the underside of the body

not sure what else u can do, just cut it...if you need to use it again $20 to have it welded

also yes mufflers could have alot to do with it...but this is more of an economy built car, they aren't necessarily going to put the most optimal exhaust on the car. 1.75" sounds about right to me but I've been wrong before...I've got 2.5" piping and it didn't help me either way so

Clmbngfrk18

well the thing is is mkulrey13 needs a stock system to pass inspection in nh so im gonna give him my system plus some cash for his dc exhaust that way we both win but i was trying to do it w\out cutting

1.75 for after cat diamter, and before cat is 2.25-2.5

Clmbngfrk18

thats what i thoguht fell free to lock this thread im all set

IonNinja

before the cat is 2.25" or 2.5"?

either way, thats good because then I won't need a downpipe for my Pacesetter made...

CobaltCowboy

i'll bet my pink slip it don't stop here.

Clmbngfrk18

well who knows technically here in mass any system other than stock is illegal but most places dont care

dnbguy86

The piece that comes after the header, but before the cat is 2.5". After the cat but before the rest of the exhaust is 2.25'. Now the the rest of the exhaust is 1.75".

IonNinja

sweet, so i don't even need a downpipe made

although that 2.25" could be replaced with 2.5" to have me at 2.5" all the way back...I'll probably just leave it as is with the Pacesetter.
