if i were to custom make a catback system or just straight pipes to reso and muffs what kind of things should i be looking for? like how big piping etc etc (i dont really know much about exhaust). i am looking for sometign simliar to stillens catback system for the na z's and with the same similar sounds at idle, low rpm and high rpm cause its a deep growl =) (compare to mind which sounds like firecrackers above 3500rpm). Btw its a 2+2 n/a so any recommendations would help =) .. i was thinking just no cat 2.5 piping to a pair of stillen reso+muff but donno if stillen sells muff+ reso seperate or ...sebring tuning reso+muff. if you have any suggestions please tell =)
also ...is backpresssure nesscary? |

You have the right idea.
Regarding the size of the piping I am not to sure, when in doubt go only 1/2" bigger than the stock exhaust. Back pressure is necessary in a na car.
Replace the cats with good resonators, and put on whatever mufflers you like. Just remeber what ever componets your custom exhaust has you have to have some kind of cross over pipe. Unless of course you convert over to single exhaust.
Your best bet is have the car on a hoist so you can see what your dealing with.
Best of Luck

X-pipe or H-pipe, doesn't matter. At the level of performance in an NA its not going to make a huge difference between the two. For Twin Turbos the x-pipe is arguably the better design.
For custom exhaust work I can recommend Atlas Muffler on 99st & 51ave.
If you want a complete system built for you, or want quality pieces sent up, and don't mine paying for shipping, contact the guys down at specialtyz.com in California. |

| hmmm "backpreasure" i hear yes and no on that one so =\ isnt it better to have no restriction? H & X pipe i heard H pipe has a lower tone while x pipe has a higher tone |

I would have to say in my experience with NA cars, if you have a less restrictive (i.e. less back pressure) in you exhaust, you will give up a bit of bottom end torque to gain top end power...
Personally, if I had an NA, I would stick to having good bottom end. How often do you need the top end power? If this vehicle is used mostly as a street car, I would stick to keeping a good bottom end. Maybe if the car is a track car, you would prefer having a good top end.
With a turbo charged car, it doesn't really matter as the turbo is giving you the back pressure as opposed to the exhaust system. Changing the exhaust system on a turbocharged car can have the effect of allowing your turbocharger to spool up a bit sooner without sacrificing the initial off the line power.
BTW, Hello from England. I'll be back next week, but I'll probably miss the monthly meeting. |

The x-pipe design is supposed to offer a torque advantage. Has to do with the way it blends the exhaust pulses. |

Magnaflow BUT!!! not that cheap crap from magnaflow that you can get from crappy tire or of the rack like that. If you want a sweet tone from a magnaflow exhaust you need to get their top of the line mufflers which are ordered in from shops or else your car will sould like ass if you get their cheap crap. |

Mine has Magnaflow mufflers welded onto the stock pipes. Came that way when I bought it in 2002. Great sound, polish up nice, and no structural problems through 3 years of year 'round daily driving.
They are the 14833 Street Series Polished Stainless
and I've put 30 000 km on them and been quite happy.
They were installed through Thrifty Muffler West End (I have the receipt from the previous owner) and look something like this:
However, I will be at Specialty Z in California next Monday and I'll ask about N/A products. There is a new outfit that Greg Dupree is working with called Fast Intentions that will be supplying his exhaust products. I'm highly interested in his cat-back systems, and will find out more when I'm there.

In addition to length differences some of the hanger mounting spots are in different locations. I'm not sure an *extended* 2-seater exhaust would line up everywhere properly on a 2+2.
But to know for sure you'd have to talk to some who's tried, or at least owned both configurations and knows the differences intimately (Gord's a good bet). |

You're going AGAIN? Or is this the sp500 trip you mentioned at the last meeting?

ahem... *cough* x-pipe *cough*. You still have the option of buying half a catback from me. I still have the B&B X-Pipe (non-resonated), if you're interested. |

Jason, what exactly does the the resonaters do? I'm going to be picking up an aftermarket exhaust system but it comes with an H pipe..the X pipe you have, would it work with the hks turbo exhaust system:dunno: |

The x-pipe I have is interchangeable with any of the stock and properly-designed aftermarket exhaust components. It will bolt up to stock cats on the front end, or test pipes. And the other end will mate to stock muffler sections or any of the aftermarket 2.5" muffler sections.
Resonators just serve to quiet the exhaust. A full B&B catback (w/ non-resonated x-pipe and mufflers) is one of the loudest exhausts you can have on a TT. But the non-resonated x-pipe combined with other mufflers such as Stillen, Borla, HKS, etc. won't be as loud. |
