Air filters
I was hoping someone could & WOULD answer a question for me. If I switch to an Air raid or F&N filter, do I also have to change the exhaust? I know that if a motor breathes better it also needs to get the exhaust gases out more efficiently. Do these filters necesitate a change in the exhaust? Can I just switch the filter & leave the exhaust stock till I can afford a new system?
Any help will be appreciated. Thanks in advance.

Hello from down South. You will not need to change your exhaust because you add a K&N Filter. Some Folks in here believe the K&N Filter lets in to many dust particles. I have one in my truck and never had any problems. The truck breaths much better with the K&N than with the stock air filter.

Hi Cowlady;
It's $50. vs. $200. for either the K&N filter or the Airaid FIPK. Personally I think the K&N filter inside the stock airbox is all you need unless you're looking for tenths of seconds off of 1/4 mile drag race times. $50. bucks for the K&N filter is money well spent. $200. bucks for the Airaid is ok if you can afford it...
Add the K&N filter and you'll notice an engine that 'picks up' a bit quicker than the stock paper element allows. Not a huge difference (in fact it's very minimal) between paper element and K&N but when you do your exhaust mod, you'll want at least the K&N filter.

The factory intake and exhaust is restrictive. The muffler only is a good improvement and so is the K&N filter only; if working with a budget. The biggest improvement I got for the money was removing the 2" air cleaner to filter extension, and replacing it with 3" (total cost $5). I was waiting on the 2000 CARB certification from K&N. Good Luck !
