Hi i want to bought the zzp 3" downpipe for my coby. I have already the 2.5" magnaflow cat back. Does this dp will fit on stock manifold and my cat back and which option i have to pick and last thing cat or catless. Thanks

 

Yes it will fit. More hp with catless but you're car will be loud as hell

 

Thank and which option i have to pick because i dont want to make something wrong. Thanks

 

you can have the 3in dp just make sure the flange is 2.5in to fit your exhaust. I had a catless dp with a custom magnaflow exhaust and it was quite loud. If you go catless it will be a tad bit raspy so dont be surprized when you get it installed. A highflow cat would help eliminate most of that but you will lose some hp. just my opinion its up to you man!

 

And what was these option : 1: extra bung and 4: prepaid label. Thanks

 

extra bung would be for your wideband gauge. if you dont have one dont get one. if your planning to get one eventually then get it and go to an autoparts store and get an oil drain plug they should fit into the hole.

 

I have the ZZP 2.5inch DP with highflow cat on it and wide band. even with a highflow cat its still pretty loud under wot but normal drivin its pretty quiet. i bought the DP with wideband and they sent me a plug for the hole. so u might not have to get a plug i didnt. anyways ZZP is great. DP looks really nice to and sounds good under woot and will give your exhaust that extra sound it needs.. anyways.. GL and enjoy it..
