Well, this is Problemish, the DC-Sports Cat-back is on back order, should I just get the Greddy EVO2, or should I wait and get the DC...

In the past I was hooked on the evo2 because of what it sounded like on my friends Prelude. Than I got a call from another friend doing the install on a tc. It sounded kind of ricy and raspy. Overall I was disappointed, hoped for a deeper sound.

I personally have the magnaflow catbck. Heres a link to someone who has a creative compacts catback with a magnaflow muffler. Sound the same as the all magnaflow catback. Though I highly recommend not getting the CC's exhaust because of reported clearance issues with the piping and the underbody.

hope it works

If you wanted to run dual exhausts would you need two injen axlebacks??????? No. you would have to get it custom bent as far as i know.

Do dual exhausts have 2 mufflers, or does it split off back of the muffler?

From a performance standpoint, you wouldn't want dual exhaust on this engine. It's a single-bank setup unlike a V configuration. To an extent, some backpressure is a good thing on a street engine.

Most 4cyl engines you see on the road with two exhaust pipes are not true dual exhaust. They are a single header into a single pipe and then split out into two mufflers or a single muffler with two outlets.

Unless someone releases a dual-chamber muffler for this car, it would have to be a total custom job, and you would have to pay careful attention to not increase or decrease the backpressure too far outside the boundaries of what the engine was designed for.

Backpressure? Needed? Interesting. Wrong, but interesting. Sounds like you've read a few too many magazine articles.

My dad was a race mechanic for 18 years and has owned his own shop now for 34 years. I understand where you are coming from, and you are correct. Low displacement, high-rev engines thrive in a low backpressure environment, but as you know there are other factors in insuring you have everything working properly from fuel management to air delivery. It's really more about exhaust velocity.

It's all about exhaust velocity, or even more accurately, exhaust energy. Backpressure is what the guys who don't get it say. Sounds like you get it though.

It's not just hi-rev engines though. All engines work off pressure differentials, and managing the differentials is what is commonly called tuning. Exhaust tuning is all about finding the right sizes and lengths to minimize energy loss and maximize pressure differential between the cylinder and atmosphere.

i have a base model 2009 tc with an automatic trans, and a trd cai
a pretty extensive explanation of "backpressure" was posted by you, and im sorry if i sound ignorant, but you sounded pretty knowledgable
the way i understand it, for the most part open pipes are ok, at least without too many high perfomance modifications
a buddy of mine who owns a shop, cut out my stock muffler, a big chunk of metal out of my system
was the way he explained it
he thought the size of stock pipe from the cat back was ok
its a touch louder than i really wanted (although i spent three days running down freeway on-ramps listening to it with my radio off, and windows down)
i am planning to "chip it" to get a bit better performance,
i also wanted to make it shift harder (because it is a bit loud) to get rid of the "bogging down" sound when city driving, stop light to stop light at low rpms
im not going to build this tc any farther
i guess my question is:
will any kind of a muffler and /or pipe (bigger than stock?) from the cat back make enough of a difference in quieting things to warrant adding, without reducing whatever (if any) performance i have gained?
or should i just throw the factory muffler back on?
