Cool High Flow Cat.

So im looking to buy a high flow cat because im on a budget and i know this is a quick way to get some more power.

How much exactly is a high flow cat, and what is the best one/brand to get.

Also how much is it for a shop to install one of these for you?

Will i feel an improve on throttle response or acceleration after one of these?
or would it be better to just get straight pipes.

i have dual exhaust btw so would i need 2 or 1?

thank you so much.

What year and trim is your car?

Please add your year and trim of your vehicle to your signature line. That way when you start asking questions in other areas of the forum, we all have a better idea on how to assist you. Click on "Quick Links" above, go down to "User Control Panel" and then click on "Edit your Signature" It'* pretty straight forward from there.

I use the free flow cat from ZZ performance, I think it'* about $70, getting it installed will depend on the shop, but $100 or so can be expected. If your car is a 2000+ you wont be able to use that cat. Purplehaizer has a link to the one you will need then.

You wont gain any HP, but can get back what was lost over time due to restricted flow. If your old cat is bad you may feel a bit of a difference. Likely you will here a difference though. The tone will go a little deeper.

As for removing the cat, not a good idea. You will trip SES lights and fail emision inspections.

No such thing as a high performance muffler. Just ones that sound better. Your not going to add HP with a muffler. If you want sound, put on a pair of series 40 mufflers. Putting in a good free flow cat will help open up the exhaust a bit, that will be needed if you want to add more HP to the engine. But the cat it'* self wont add power. As I said, it can give back some that'* been lost due to restrictions.

So then whats the cheapest mod that i can get done by a shop for not too much money that will add a boost to my acceleration. I would like to get a FWI but i would kill my engine if i tried to install it myself LOL. so i would have to get a shop to do it.

How much would a good FWI or CAI cost and how much would it cost a shop to do this.

Take a look at ZZ performance and Intence racing, they both have FWI. I made my own for under $100, there'* a write up on that in the performance are in tech info. What a shop will charge is hard to say, each is different. Personally I say do it yoruself. It'* really not that hard to install one. Post where you are located, there might be a member near by that can help. I help other members all the time.
