What kind of hi-flow cat would be best with a magnaflow catback? how much louder and power increase will it do for a 2.2l?

 

No one has a hi-flow cat and can reccommend a brand??

 

buy the magnaflow hiflow cat, from everyone i hear they are a really good company, the exhaust and parts are great,

 

how much will this increase power and will it make my magnaflow catback louder?

 

i dont really know about power but i know it will probaly make it a little deeper, i dont know about alot louder, probaly a little help on the power but not alot

 

do you know what size i would have to order? im going to get the stainless one cause my catback is stainless but i dont know what size to order.

 

get the magnaflow high flow cat, just dont buy it from magnaflow.com, cus they are way too overpriced

let us know how it works out 4 u

you could also get the XTC downpipe with cat at www.Cobalt-Addiction.com
(middle DP)

 

Just get the cat from an SS. it' flows fine for us and doesn't throw codes.

 

so if i get a magnaflow hi-flow cat it will throw codes?

 

Well actually, the stock SS/SC cats have been having problems with clogging. And if a clogged cat goes unchecked then you can really endanger the life of your engine.

But to be fair it seems to be more of a GM cat thing and not jsut an SS/SC thing. So swapping to an aftermarket hi-flow cat would be a VERY wise investment. Not only in performance but also in engine-life.

 

go with the XTC no probs with cels or anything... great product. plus it doesn't have the raspy sound the magnaflow cats have (they use vibrant ss ones)

 

I have a Vibrant one and it sucks. I custom made a downpipe with the stock flex flange and a modified rear flange for a full 2.5" mendral bent downpipe. The Vibrant cat causes my exhaust to sound like a damn honda and throws CEL's all the time. I'm going with the XTC one when I return home.

 

so will the magnaflow hi-flow cat throw a CEL or no?

 

i dont know if it would throw a cel.. i'd like to find out what hiflow cat to get with my gmpp performance exhaust.... i'm thinking of a ceramic pascsetter header as well... i've heard lots of good things about xtc downpipes....

p.s. nice lookin 'balt wdsoccer.

 

what exactly is a CEL?

 

XTC USES a vibrant... and I have it and it doesn't sound like a honda at all... and I have full 3" exhaust.

 

no CEL either

 

means check engine light

 

does anyone have a magnaflow hi-flow cat or know if it will throw a cel

 

I think ZZP's downpipes use em... and the ones I heard sounded like crap

 

plus the one guy that was still using one around by me (nhoj) had the pipiing crack off at the flange so he's returning it to buy the XTC

 

will you pass emissions with an aftermarket cat? the lame people at m local muffler shop not only told me they couldnt put it on, b/c it would be illegal, but it would void my warranty and i would fail emissions

 

yes it will pass... with OBDII they just make sure your not throwing any emissions codes... and if they do an inspection it just looks liks a cat

 

does any one have a magnaflow hi-flow cat and not get a cel

 

i would not go with a magnoflow Dp...go with cobalt addictions downpipe...its a great downpipe.
