is the exhaust pipe size 2.5 or 2.25 or 1.75 like the base..i have a catback on my base thats 2.25 and i could just put it on the 2.4 if i get it

 

it is 2.25 on the 2.4 i believe. not positive. but i think it is the same as the 2.0

 

so its pretty much already got a catback exhaust except for the muffler right? only change would be the header?

 

yup, technically. but they make other ones for the 2.4 that are 2.5" and 3" custom ones

 

my corsa is 2.5 and is a nice improvement, but yeah the 2.4 and 2.0 both come with a factory tuned exhaust changing the muffler would be fine for a small increase

 

thats what I did just changed the muffler, maybe later I'll go with 2.5 in. For sure I'm gonna get a Hi-Flow Cat.

 

Anybody else sure on the pipe size. I was always under the impression the the 2.4 and 2.0 got 2.5.

 

i measured my stock 2.4 pipe at 2 inches i think

 

I was quickly checking the site and had a good laugh at the post name "Pipe Size".... If this post would have had the *NWS* tag , I was not opening, end of story !!!!

 

Its 2 1/4 Cuz When I Was At The Muffler Shop The Muffler Mounted Right On The Pipe And Its Inlet And Outlet Are 2.25

 

If it's like the SS/Sc and Ion RL are pipes are 2.5" up until the rear suspension and then they made it 2.25" a lot of people just step up the 2.25 to 2.5

 

Korax.. how loud is your 3 inch. i was thinking of getting the vbrant setup, but is three inch going to be too loud

 

It's not bad driving around town...but it drones pretty bad at 70+mph cause the speed limit here is 75mph. It's pretty deep sounding also. If you want a quiet muffler and have a nicer sound only when flooring it I would get a hi-flow chambered muffler. It would be as good as a straight through one but it wouldn't drone on the highway.

 

i had a custom 2.25 flowmaster exhaust with a longer resonator, before i put the catback on the and just had the muffler, it droned bad from like 3k rpms to about 4 or so .....put i put the whole exhaust and longer resonator, didnt make it any louder but a lot deeper and it didnt drone at all

 

Thats what i was thinking it was. Looks like i'll just be replacing that 2.25 portion with 2.5 and a muffler. Thanks guys

 

yes it should be just like the ss/sc / RL in that it is all 2.5 until the back 1/4 where it drops to 2.25.




the setup that im selling right now is perfect. replaced the over the axle part with 2.5 and then have a 2.5 magnaflow muffler and IMO has no drone periods. its beautiful and when you down shift or left it engine brake ........ OMG its just a beautiful deep mean sound

 

The Solstice comes with 2.5" piping all the way back. It's one of the improvements the car has over the various other 2.4L VVT based cars that helps it have a higher rated HP value. Unless you're planning on producing well over 300HP the 2.5" pipe sizing is more then enough according to several of the supporting vendors at the solstice forum. Some have tried 3" piping and seen a very small increase in power over 2.5" but at a much larger cost and a much greater increase in 'raspy' sounding exhaust note.

 

So the base cars have 1.75 the whole way back or does it change like the SS? I'm gonna do a 2.5 catback made at my local muffler shop, what kinda magnaflow are you guys using? And what length resonator or stock? Part # on 2.5" magnaflow plz?

 

in my opinion i would not go for the 2.5 piping and the high flow cat unless we can get some good tuning. i have 2.5 piping with a 2.5 high flow cat from my header to resonator and my car has been parked for three days. im having some major problems high flow eficiency and maf sensor lighs coming on. to much air flow going in and to much out. i would just replace the mufler and leave the rest of the exhaust alone. just my opinion

 

Selling this upgrade are you? How 'bout posting some info...

should probably know this by know, but what do u guys mean by "droning"??? thanks!
