Supercharger question

I want to put a Whipple Supercharger with headers on my 2013 SS. Do I need to change the fuel pump, and what size pulley should I order?

At a minimum you'll need the ZL1 pump and a different FPCM but you're probably better off upgrading from the start depending on your goals.

The 4" pulley is a good place to start, again depending on your goals.

Is there any advantage to having or not having high flow CAT's on the install?

No cats- free flowing, no restriction, more power, stinky smell.
Cats- the opposite of above, and have the possibility of burning up bc of S/c

No cats, cheaper, and no worry of them melting down then coming apart and sucking crap back into the engine.
Determine end goal if you can. My setup will do a max of about 750whp on 93 octane. Stock cam i was at 575whp with zl1 pump and fpcm programmed. If you're going to run e85 or want more than 700whp consider going with a dual or triple pump setup. You can also do a dsx aux pump that is slightly cheaper and will support about 1000whp on 93. On 100 octane i can put out about 800whp on my set up.

If you're keeping the stock cam, you can stay with the stock fuel pump, but would need a boost-a-pump.

Would the car be much louder would the car be without high-flow CATS?

They can be pretty loud without cats. But you can run a resonated x pipe it might help keep it quiter. My car is loud as hell on cold start and under acceleration, but pretty tame cruising

When I bought the Whipple kit it came with a boost-a-pump. I'm running stock pump with just the BAP and stock headers. I would think you'd be ok with just headers on a stock pump with a BAP if you go with the 4" pulley. If you start going smaller, you would need at least a ZL1 pump. I'm guessing you're going to get it tuned when you do this, so would be worth asking the shop who is doing the tuning what they think.

In the future, I'll be doing the exhaust, changing the pulley and getting a better tune, when I do that, I'll be going to at least a ZL1 pump. If you want more power, buy the pump(s) that will get you there the first time so you don't end up buying and changing twice.

The Whipple kit will come with a bap unless you get the tuner kit. If you plan on adding more power down the road the tuner kit is a better option. Go ahead and get a better pump option and injectors right off that bat.

Yes off road pipes will be louder and raspier then having high flow cats. On boosted applications cats will burn up quicker too. If it's not a daily driver or something that has to haul the family we usually recommend off road pipes.

When you're ready to get that Whipple hit us up. We'll get you the best price by far.
