Just got out of the Honda game . Just got my Balt ss sc. Im bout to get a 3" ZZp DP and a 2.5" cat back. Im gonna hold off on a header. My question is, will a 2.5" or 3" DP bolt on the stock header?

 

Yes, just make sure when you order it to select the 2.5" dp flange on the catback.

Reason I know. Just sold my Hahn which was a 3" with a 2.5" DP flange that was bolted to stock DP.

 

So ill be good with this

Stock header-->3" downpipe-->then 2.5" Catback?

 

Ahhhh...Yeah you'll have to get a 2.5" header >> dp flange and then a 2.5" dp >> catback flange.

 

No worries about rusting or paint flaking off. It costs a little more but we feel it's worth it. All welding is done to the strictest of standards and bears a professional finish. Weld quality is higher than any other downpipe manufacture and a sample of one of our welds can be seen here: WELD We promise our welds to be 100% leak free. Even the flanges are stainless, which isn't something most companies can say. When shopping around, ask if the downpipe is 100% 304 stainless, ask for a close up shop of their weld. You'll know right away, what true quality is and what it isn't.



Seen below, the stock pipe narrows down to a 2" hole before lowering into the cat. This is very restrictive, causes KR and a loss of HP.



Our 3" stainless, bolt in offroad pipes remove all of the stock downpipe restrictions. No more 2" inlet, no more O2 bung dimple, no more Cat. By doing so gains of over 15HP can be had along with a substantial drop in KR. Most users can drop a pulley size after adding our downpipe.



Available in multiple configurations.

3" weld in version has a straight 3" pipe exit and requires welding to a custom exhaust system.

2.5" bolt in uses a 3" downpipe and reduces to 2.5" flange at the tail section so it can bolt up to a stock or 2.5" catback.

3" bolt in mates to our 3" cat back exhaust system without any welding.




My best bet would be to ask ZZP >>>> Email Tim @ turbotim@zzperformance.com

 

ooooh okay so a 2.5" or 3" downpipe stock he wont be a direct bolt on the stock header..

 

lol i meant a 3" or 2.5" dp wont be a direct bolt on to the stock header..

 

so in order to put a 3" down pipe on I have to upgrade my header?? itwont fit on the stock one?

 

No. It'll fit fine.

I'm running a 3 inch zzp downpipe on stock manifold.

You want the 2.5 flange at the end though so it'll connect to the cat back. Or you could have it welded.

 

Okay thanks man

 

zzp has the option, choose 2.5in bolt in flange so it bolts up to the 2.5 in exhaust... the top part that connects to the header isnst an option to change (bolts up to aftermarket or stock header)

 

Okay so would a 3 inch zzp dp wit 2.5 exit fit the stock header ?... I read yes and no all over this post , go!
