I have covered the shorty style headers and hi flow cats etc in another topic. Here are some of the cat back systems your likely to see on the market.

ATR
Bassani
Borla
Bosal
Focussport
HKS
Magnaflow
MBRP
Pacesetter
Thermal R&D
Trubendz
Vibrant

There are many issues to discuss when talking about cat back systems. Here are a few of them.

SOUND
One thing an aftermarket system will always have over stock is a distinctive sound. Sound is a personal choice, whether you want it to be loud and deep or quiet and rumbling, there is a cat back setup for you.

Many systems are much louder than stock. When this becomes a problem especially when combined with a race header, you have a few things you can do to quiet your system down. Focussport offers a stealth option which adds a resonator to the system, Bosal also offers a silencer kit which helps tone things down. Trubendz offers the ability to customize your set up by choosing your own muffler and resonator.

PERFORMANCE
This is to me one of the most important aspects of a an exhaust system. To start with, when choosing your setup, you need to take into consideration some of your future plans. If you are planning on staying relatively mild and just using bolt ons, then a 2.25” system will be more than enough for you. However, if you plan on a serious N/A build or the use of forced induction, a 2.5” system will provide much better gains. Borla, MBRP and trubendz make the best 2.5” cat back systems

PRICE
Cat back setups can run anywhere from $ 250 all the way up to $ 500, its up to you what you want to spend. The gains are not increased by spending more

Flexpipes

The flexpipe is the last bottleneck in your exhaust system, many folks buy the other system parts and forego a flexpipe. It has been dyno proven that replacing a stock flexpipe in an otherwise complete, full length exhaust setup is worth a few whp and wtq.

Here are some of the aftermarket flexpipes you are likely to find.

Bosal
Focussport
Focus central
Trubendz

The Bosal flexpipe is stainless steel, while the focus central and focussport are not, though the focussport piece is ceramic coated, all of these are 2.25”. Trubendz is the only company currently making 2.5” flexpipes, trubendz also makes their flexpipes aluminized and stainless steel.


If you have a question about one of these parts or another related exhaust part, feel free to PM me or e-mail me at [email protected]

Trubendz also offers 3 inch size tubing, that is good for going Forced Induction. If your not going to go FI, then don't get 3 inches because the focus isn't a school bus. 2.5 inches is also ok for FI too but if your planning to go big then ya might wanna go 3 inches.

I didn't want to use the FJ info because I do not think its completely correct.

I also do not like posting other forums topics on this one. For example, cross posting FJ and FF.

i heard that in order to install a cat back system you have to drop the back axle to take off the stock system is this true? also how easy is it to install it yourself? thanks.

Most folks like mofo said cut off the old exhaust system.

Most new systems come in multiple sections.

Yeah when I put mine on I cut my stock exhaust off. I also LOVE my MAGNA FLOW!!!!! its the bomb. I like my Bosal Flex too. I like the look of it and the fact that it doesnt rust!! thats dope. When I took my exhaust off my old focus and put it on my new focus I saw that my exhaust system didnt rust, except for my Focus Cental Hi flow Cat. The flex and Cat back lookg like new even though they had a good 10000 miles on them. So go w/ the Bosal on the flex yo!

I have been comparing price for a borla exhuast system. Is there much difference between the "Trubendz" Borla muffler 2.5 catback and a complete Borla catback system? The mounting point are in the same places and they are both cmprised of stainless steel. Because for a hundred bucks cheaper I can buy the "Trubendz" version and get another midprice mod with the leftover cash and some extra money.

Any input would be greatly appreciated.

Please PM and let me know.

Thnx for the reply.

I think they are of the same construction. I just don't know which one to choose?

Anyone else have any input?

Well I have a regular Borla setup. I honestly haven't seen a trubendz kit so I have no idea of the quality. I did however have one of their early 2.5" flexpipes and wasn't impressed.

If you can't afford the name brand, you can take a risk on theirs.
