Magnaflow Cat Back

Alphawerks Headers

AEM Short Ram

but now I was wondering would it help alot if I had a test pipe on there instead of the stock cat? jw.......O and are short shift kits worth it?
Thanks!

 

if you dont have the resources or money to save up/get a hi-flow cat then the test pipe is ok...but 99 times out of 100 i will say save up the extra 40 bucks to get a universal magnaflow hi-flow.

and yes. short shifters are totally worth it.

 

Go to ebay and buy a Magnaflow High Flow cat, I paid $44, shipped I believe. Test pipes are usually around $30 shipped, spend the extra $14 it'll be worth it in the long run.

 

what is the diff between test pipe and high flow cat other than appearence...can u pass emissions with it?

 

No, you won't pass emissions with a test pipe.

 

i kno u wont pass it with a test pipe, i was asking will u pass it with a high flow cat. considering it still is a catalytic converter which would mean it should clean the exhaust but since its "hi flow" that means some of the restrictive parts of a normal cat that cleans the exhaust would prolly be eliminated in turn causing it to not clean the exhaust as well...i would imagine...

 

another name for a test pipe is a straight pipe...meaning its just a pipe replacing the cat. so no...you will not pass emissions.

 

bahhh i knowww my magnaflow came with a test pipe and i even ran with it in for a couple weeks. my question was will u pass emissions with a high flow?

 

You should pass with the high flow. Considering the magniflow high flow's come with a 50 state street legal thing.

 

forgot to ask this question...do hi flow cats change the tone of the exhaust or make the exhaust a good bit loud like a test pipe would?
