the corsa touring sounds sex


i would say zzp longtube with 2.5" bolt in to keep velocity

 

If you want they will make it, I have a 2.5 lth bolt in option.

 

i think the primaries in the header will be too wide also. is there someone from zzp that i can speak with.

 

isnt that only for the exit? is it ok for the rest of the piping to be 3"?

i know they did a 1-5/8" primary version before, that what maven is running

 

Thank you

 

I will stick to the larger primaries. I had their mid length on my 2.4 with the larger primaries and lowend tq was still enough to spin the tires for a good 5 ft with an auto. And it pulled hard uptop.

 

link for the midlength???
cant find it on zzp's site

 

Honestly just stick with the longtube. The midlength performed well but they are prone to leaks. Was just saying I dont believe going down in primary size is needed with the 2.4

Maven also ran the smaller primaries on a 2.2 L61 engine. Not the larger 2.4 LE5.

edit: actually it looks like zzp no longer makes the mid length

 

what is the stock primary size?
the longtube is 1.75 and the mid is 1.50 right?

 

Not sure on stock size. But im running a shorty right now and even it registered on the butt dyno as making a bit more power.

But the long tube is 1 3/4 and the mid length was available as 1 5/8 and 1 3/4 as well I think.

 

So would of been a better choice for the ZZP Long Tube Header Package the Off Road 2.5,3" catback or the one with Cat 2.5 3"?
