Hey guys, I've got a stock 2.2 and I'm looking to get a whole new exhaust setup. I'm thinking I want to get the ZZP midlenght header/downpipe combo with the Magnaflow highflow cat and the Magnaflow catback. First off, anyone have this setup? Before I buy, I have a few questions:
1. First, will there be any issues due to the fact that the dp is 2.5" and the catback is 2.25"?

2. If so, will the 2.5" Magnaflow catback for the SS fit on my LS?

3. Should I go with the 1.5" inlets or 1.75"?

4. Is the ceramic coating really worth the extra $100?

5. What is the "extra O2 bung for wideband" and is it necessary/recommended?

6. Does anyone have a link to a good how-to for the install?

*note: I do not plan on upgrading to forced induction

 

1. First, will there be any issues due to the fact that the dp is 2.5" and the catback is 2.25"?

nope, it should bolt right up.

2. If so, will the 2.5" Magnaflow catback for the SS fit on my LS?

yes, it will fit. i have the magnaflow with the zzp, and it sounds amazing.

3. Should I go with the 1.5" inlets or 1.75"?

1.5". 1.75" will be too big.

4. Is the ceramic coating really worth the extra $100?

it's a good thing to have, not necessary. but over a period of years, the ceramic will hold up better than the non-ceramic. but the non-ceramic isn't going to fall apart in a year. from my experience it will hold up better than stock.

5. What is the "extra O2 bung for wideband" and is it necessary/recommended?

a wideband tells you your air to fuel ratio. if you're just going to do these mods, it's not really necessary. it's basically for people that are going to be doing more mods, and especially for tuning reasons so that you can make sure you're running at a safe ratio.

6. Does anyone have a link to a good how-to for the install?

when the time comes, shoot me a pm if you need help, i'll walk you through it step by step. it's not that hard at all. if you can unscrew bolts, and tighten bolts, you won't have any issues with this. some of the bolts are a little hard to reach, but with basic tools you should be fine.

 

thanks for the help! since both exhausts fit, which would you recommend?

 

PM us if you are interested in parts, we can check stock and get you a discount.

 

2.25 the 2.5 is a little big for a 2.2

 

ive got a magnaflow catback and i love it!

and...ive heard of guys changing their downpipe and putting on a highflow cat, and they lost a bit torque...this because the naturally apirated engine pretty much runs on that back-preasure
but if you do change it, that ***** gonna sound GOOD!

 

now the fun part.... which component is going to void my GM warranty? if not all of them..

 

Maybe a catless downpipe but thats it.

 

i recommend not getting magnaflow :X It sounds like **** on my neighbors Ford Focus.

Maybe so, but the thing is, the same brand of exhaust can sound totally different on another car. Even the same exhaust on a 2.4 and 2.0 sound different. You can't really use a Focus as an apples-to-apples comparison.

 

thanks for all the advice guys! do you guys think this kind of setup will give me the best gains or like KyleMinnis said would I maybe get more performance if I keep the stock dp and go with something like the CA shorty header? Also, if there is a difference would it be very significant?

 

come on guys, a little help with this last question please?
