I'm wanting to remove my air pump for a number of reasons. Currently I have:

Random Technology 4" high-flow metal matrix pre-cat (custom welded into a pettit racing down pipe)
Pettit Racing high-flow main cat
Pettit Racing (Racing Beat) 3" Stainless exhaust (dual tips)

Now, I know you shouldn't remove the air pump unless the main cat is removed/replaced, but since I have the Random Tech high-flow pre-cat and also the Pettit high-flow main cat, I'm wondering if it would be OK to remove the smog pump.

Thoughts?

 

I'd probably ask Pettit if their high flow cat requires an air pump. The metal one from Random does not (i'm running that as a main cat). I know that Nick at N-Tech said that his would be fine w/o the air pump. Others might be different.

 

just talked to pettit on the phone:

they said their high-flow cat does not require the air pump, but keeping it will extend the life of the cat. since i plan on replacing it with a resonated mid-pipe in the future, i guess i'll be removing the air-pump next week.

 

Does anyone know some place that custom welds the Random Metal cats into a midpipe or downpipe for a guy or that sells them premade? Way cheaper than Knightsports.

 

not sure, the previous owner had this one installed. i'm sure you could get any local exhaust/muffler shop to do it.

i actually want to sell mine and go with a straight downpipe. we don't have emissions here in FL so i don't really need to worry about having any sort of pre-cat. i'm sure it only has a couple thousand miles on it. my car just hit 30k original miles and the previous owner said he only recently had the exhaust system done.

 

I had never even thought of placing one as a precat. If one did and used it for the main also you might have pretty clean emissions. Did you ever notice any boost creep or spikes?
