1st I been researching some information on a midpipe or racepipe... and the most i read Im getting a bit confused... like for example RP has a midpipe that has a straight cat or high flow cat and race pipe has no cat... now what is the difference if i go to a muffler shop and tell him to run a straight pipe from the headers to cat back would that be the same .... i have the greddy catback system what midpipe is compatibla with greddy's

2nd would i be getting a CEL in if getting one has anyone found a way to fix that


3rd i am looking for a intake? so far i like the k&n but i remember there was issues with old version of it any problems with this one?

and is there a better one and around same prize

where is the best place to order any of this parts...or actually the cheapest thanx guys

 

I'd get an AEM cold air intake.. hook it up in front of your radiator.. mad air

 

If you ran a pipe from the manifold (or header if you put one on) that would be the same as a test pipe. It would be loud, illegal on public roads, you would get a cel (either lit or not, it would be stored) and give you the most chance for >hp. make sure they weld in a oxy sensor bung. Despite some threads to the contrary, there is no fix. Do a search for why, but it basically is because the ecu tests the cat function by fluttering the afr. No standalone fooler can fool that.
