Thread: Supporting Mods.

Well all this while I thought i had a zzp pcm because thats what the previous owner told me.. well turns out its an Intense pcm. So can anyone tell me if i have enough supporting mods for my setup.

-Intake
-Intense PCM
-Flowmaster Hushpower Muffler
-High Flow cat
-U bend delete and resonator delete
-180* tstat
-3.5 or 3.4 pulley

probably not. you're most likely knocking because you havent even taken out the restriction in your system (downpipe).

^^This

Get some headers but the most important thing is scan scan scan

are the speed daddy headers any good? They come with the downpipe too right

I have em... with headers you dont have a downpipe. They come with a sink trap and some extra pieces.

Do you think i should buy the speed daddy's?

There are mixed feelings about them but from personal experience I have got them seal up with better band clamps and have no complaints.. For 220 shipped cant really go wrong.

Well for one...measure the pulley...that'll tell you the size of it...that ain't hard. Considering headers used to be a grand...$220 sounds pretty good to me. Read the thread in my signature.

-Intake=yes
-Intense PCM=yes
-Flowmaster Hushpower Muffler= no hp gain, all preference
-High Flow cat and U bend delete=go headers
-resonator delete=might cause car to sound raspy
-180* tstat=yes
-3.5 or 3.4 pulley=with all the mods above, you should be good for this

as for headers buy these!
