New "go fast" parts

It's a catback exhaust system. Cool stuff. I'm actually looking to pickup a Magnaflow catback for my car soon.
 
slvdr: There are two kinds of mid pipes for stangs at least. An H pipe and an X pipe. You can pretty much tell how the design is. My intake I got for around 160. its been a while but its a good peice. Better than that metal/chrome crap that looses power b/c of heat.



Ncal: Good choice with the magnaflow. A lot of people get it and they love it. Got a nice racey tone to them. If you do, get the magnapacks, the louder version hehe.



Thanks for the compliments
 
An "X" pipe is just another way of connecting the two sides of the exhaust piping in a dual exhaust system. This gives better performance (forgot the technical reasons why...) than just two separate pipes. You can use a traditional "H" pipe as mentioned, or an X pipe like the one shown. I think the first guy who invented this idea was Dr.Gas or somebody?
 
An X-pipe isn't a catback exhaust system, it either has new cats on it, or removes the cats completely. It equalizes exhaust backpressure via the crossover with each exhaust pulse.
 
the x-pipe replaces the piping between the headers and the mufflers. i think the x-pipes are more efficient than the traditional h-pipes, i think due to better scavenging of the exhaust pulses. and i think the nascar guys use x-pipes. :D



i heard replacing the intake elbow is suppose to give some good horsepower. any other mods?
 
Yeah, I dunno why I said catback. Only problem with dual exhaust around here is you have to be careful db level due. Technically it has to be something like sub 95 under load here. Pretty much removing any stock piping will get you more hp on these cars.

Something about the whole 'backpressure' issue has always dumbfounded me. The very idea of having some retaining pressure doesn't seem to coincide with benefiting exhaust flow and increasing engine power. Set aside noise & emissions, a well built exhaust should be designed to maximize flow and cut back on turbulence, so how would backpressure benefit this scheme.



I don't mean to single you out Matt, you just brought up an interesting issue that I'm a little unclear on...

The X keeps you from losing all your torque. Torque is what you want in the lower RPMS while the HP is what you want in the higher rpms. Also the X has a different sound than H pipes. Its more of an exotic sound than a muscle sound. But nothing like a lambo or anything like that just more racey.
 
Actually it is really the other way around. The X-pipe does make a bit more peak power than an H-pipe but, you give up some low end power and torque for more power in the upper power band. The difference is really marginal though.



A lot of X-pipes these days are purely cosmetic pieces and don't really function as a true X-pipe. A properly designed X acts as a venturi speeding up the air flow as it goes through the cross-over.



Really the only difference when it comes down to it is the sound. An H-pipe will have a more mellow rumble whereas an X-pipe sounds like others have said, an exotic sports car with a more high pitched burble.



X-pipes just seem to be the fashion lately.



That being said I am still going back and forth between a Magnaflow Catted X-pipe and an MRT Catted H-pipe.
 
I meant the back pressure keeps from losing torque. And yes X pipes get better HP gains while H pipes get better TQ gains.
