View Full Version : Question about exhaust
11-30-2002, 06:56 PM
everyone look underneath your cars, it seems to have three mufflers, I plan to have the two up front cut off and run straight pipes and put maybe a hks or a tanabe universal muffler at the end, does anyone see this being a problem?

I have heard from alot of people that if you mess with the exhaust on these you can end up losing alot. Svt has done a great job tuning the exhaust on these little rockets and even on the L's and cobra's. The focus sounds great and has plenty of breathing out the back. I guess if you have the money and want to try go ahead.
Just my 2 cents.

i agree with the above....people putting borlas and what not are not getting the hp they think they will get or are talking up what little gain they do get. 6 hp is not worth the amount of money to sink into a whole new exhaust system unless you have piles of money to spend.

I don't know where you live or what the smog police let you get away with, but if you want more hp than a full exhaust from less than $300 ($200 if you shop around) you can get a cat elimiator pipe. That is just a pipe that replaces the cat. the pipe is like 100-150 and you will need the O2 cheaters if your check engine light comes on which are somewhere in the neighborhood of $50.
As for breathing in, the most expensive (and only to date) air box replacement cold air induction for the SVTF is the AEM and gives you 5hp for approx. $300. A drop in K&N filter is worth about 2-3hp for $30.
There are dyno graphs on focaljet and club-focus.net AEM even has the dyno for their intakes on their website (aempower.com)
The short ram intake gave 2hp from 6,000-7,000rpm and matched the factory system dead on until then.
Also, if you mess with the exhaust, leave the center canister (the muffler) alone. People who have replaced it with pipe always put it back on because it sounds too ricey. And the three canisters are resonator, muffler, and at the tailpipe is another resonator.
