To gain HP or mpg you should add all the bolt on parts (headers, exhaust, plenum spacer, intake) then get an osiris tune by uprev.

must be striped then, i used deep sockets then i brought out the impact and it didnt move

 

I've been doing a lot of checking around. Who knows what manufacturers sell a bolt on direct replacement axle back muffler for an 04 sedan? I know Megan makes one and HKS did but they are gone? I really like the looks and sound of the Sebring but it looks like it needs to be welded. People seem to like Magnaflow but their website doesn't show a direct bolt on.
What are my options for direct bolt on?

 

I think you about covered it. I say get Hks if you can find one.

 

iirc IntensePower may be the only ones to still have the HKS Legamax for the sedan.

 

If you car came with No spoiler then it has a 3rd brake light in the back decklid, use that.
You will want to disconnect it anyways because it looks silly to have 2 3rd brake lights.

 

That's a good point, thanks.

 

Dont forget the High Flow Cats...

 

Oh about a million or so

 

u will get performance sound

 

got all of these mods +HFC, grounding kit.... with osiris tuner. i have G35x pushing 227 AWHP and 219 TQ. well worth it. drives like a monster after tune... more mods to go! good luck.

ph and NiSMO sticker for 500hp gain. lol.

 

That would suck if it was

Are you using an impact socket? If you are try using a regular one instead as they have thinner walls. Its been a while and i can't remember exactly what I used. How were you able to fit an impact gun? If you used an air wrench they don't have enough torque to break that bolt loose

 

Get a Honda if you want gains from a cai

 

sebring ftw!!
