exhaust

[wf_festiva]

what kind of exhaust are you all running?

[Pu241]

OEM or aftermarket OEM for me.
Would like to have a stainless steel cat back done one day.
Even just the mid-pipe would be nice.
Have change the OEM exhaust on various festers way too many times

I know next to nothing about cars... So take what I'm about to ask with a grain of salt.

How much does an exhaust system effect the performance of a car? If someone were to drop a B6 engine in a car... Is there an exhaust systems that would increase the performance without effecting the gas mileage?

Do exhaust systems have any effect on mileage?

Was running a 2,25" exhaust with no cat, one small resonator and a dual DTM burnt tip 20$ ebay muffler and was about to become deaf although it had a deep and mean tone...But at a certain RPM, all mirrors were vibrating as well as my whole head; felt like I had an XBox controler vibrating in my head the whole time. Installed a cat, and while it doesn't pop anymore while decellerating, it's still a bit loud...Too deep a tone for my taste. I'm thinking about either adding another resonator or an extra mini-muffler.

For a good thread on exhaust size read: http://www.fordfestiva.com/forums/sh...ad.php?t=16365
Especially the end of the first/and most of the second page. There are a lot of misconceptions regarding exhaust floating around.


The second post in this thread has as lot more details on my exhaust:

As I said in that thread, I used 2" galvanized conduit. I think the next size down is 1.5", which is probobly a little small even for a stock B3. However, if you really wanted to go with that size, you could. One of the benefits of using the 2" conduit is its the same size as a 2" cherry bomb (its hard to find a cherry bomb smaller than 2") so you can just butt weld them together.

Stock for now, but I have a FMS exhaust going on soon.
