I have a BBK catted X pipe, it has 2 high flow cats. My question is ifI went with off road BBK X would i feel a difference in power. I know if I had a factory H with 4 cats I would. Also I have Loudmouth 1's would removing the cats make it louder or sound different. Thanks

i had the original cats on mine will all the listed mods besides the cam and i did not feel anything after i added the MAC H pipe with 2 cats. kinda a bummer

You probably won't feel a difference without cats. Your car will be a wholelot louder. If your car sounds good now I would leave them on. That way your still emissons legal.

I only got it for inspection but after spending $400 plus shippingI thoughtI would keep it. But a new off road is under $200. I will just swap out every 2 years for inspection

you will have better response with out the cats, and it will be alot louder

I had off road H with flows but the catted X was too quiet. Thats why i got loudmouths. Someone told me it wouldn't be much louder without the cats

I read an article a while ago that said the difference between high flow cats and no cats was negligible. If you like how it is now I would keep it.
