OK, Ive decided to part with my 3" Borla exhaust for a Corsa touring. As you know the Corsa is 2.5", and I have a ZZP 3" catted downpipe with an obvious 3" hook up. What is my best option other then buying a new downpipe with a 2.5" flange? Thank you.

 

Replace the flange on the exhaust?

 

wats wrong with the Borla one ya got? 2 loud? Jus take your car to a muffler/welding shop, an have em put a "quieter" muffler on there, save ya a couple hundred dollars, work, an headache

 

I guess i dont understand the meaning of the flange. wouldnt the flange just make it be able to bolt up? with my understanding there would still be a "wall" where the DP and the exhaust meet?

 

Yup agreed. ZZP sells the flanged for like $10. Then get a 3" to 2.5" reducer, weld it on and you're golden

 

It is very loud yes lol, but thats not the only reason im replacing it, Im on stance coilovers and the exhaust is hitting off my rear beam. Also it hangs WAY to low i cant go as low as i want without hitting the pipe off the ground.

 

Would you or someone please post a link to what i need? I have looked at what your talking about but I didn't understand what one I needed.

 

You need the 3" flange. Then a 3" to 2.5" pipe. Weld it together, done.

 

Why would i need the flange with the reducer?

 

The reducer is only a pipe. No flange. So you'd have to have the flange welded on the 3" side. Then weld the 2.5" side to the exhaust.

Unless you can find a reducer with a flange already. Not sure if they sell them like that or not

 

ahhhhhh ok gotcha, thanks alot!

 

No problem sir

 

Sooooo this is all i need?

and
ZZPerformance - Exhaust Flanges # 3" option

 

Pretty much. Just make sure the reducer is 3" - 2.5" The link you posted doesn't state. And Im too lazy to look up that part number

 

lol yea it is 3-2.5

 

^ make sure you have the right 3" to 2.5". some are I.D. - I.D., O.D - I.D. I.D. - O.D.. Confusing huh? make sure the pipes are either 2.5 on the outside, or if they are bigger is 2.5 --- or 3 on the inside. if its 2.5 ID the outside will be (on a Digital Mic) 2.625, and 3 inch would be 3.125. roughly

 

How would i know that?

 

I think im just going to buy a new downpipe once my exhaust sells. seems like the new flange and reducer could get kinda messy
