Modeldriver Neutral Newbie July 13, 2003 Share July 13, 2003 Yah... means 'short ram induction' I think. Link to post Share on other sites More sharing options...
Dualie Clutched July 13, 2003 Author Share July 13, 2003 Or Short Ram Intake I'm not using a open pod. My piping is conducted into my existing stock airbox, so I guess I'm ok in this department. Thank you Keat.. Link to post Share on other sites More sharing options...
Modeldriver Neutral Newbie July 13, 2003 Share July 13, 2003 Most welcome. Do let us know what you did in the end and the results - share and exchange notes mah Link to post Share on other sites More sharing options...
Dualie Clutched July 27, 2003 Author Share July 27, 2003 Just check out my exhaust piping today. Notice there's a couple of 90 degree bend in the pipings. Will it be better for me to get an exhaust shop to 'straighten' out the piping? Less pressure drop, easier exhaust flow? Link to post Share on other sites More sharing options...
Saaber Neutral Newbie July 27, 2003 Share July 27, 2003 yes it will be better as your exhaust exit velocity would be higher.... Link to post Share on other sites More sharing options...
Super7 Turbocharged July 27, 2003 Share July 27, 2003 Are you visiting the exhaust shop soon to have the turns straightened up??.... would like to tag along and see if mine can be done also, Man??? cheers Link to post Share on other sites More sharing options...
Dualie Clutched July 28, 2003 Author Share July 28, 2003 Yeah soon... but seriously don't know when... depends on what's going on at customer site... Link to post Share on other sites More sharing options...
Dualie Clutched July 28, 2003 Author Share July 28, 2003 (edited) Some pics of my exhaust... Does the 2nd pic shows a cat? Can see the O2 sensor... I think I'm driving a 2 cat car There's one integrated into the extractor complete with O2 sensor too Abt the many bends in the exhaust pipe... it is actually bend around the fuel tank... wonder how to straighten the pipe Edited July 28, 2003 by Dualie Link to post Share on other sites More sharing options...
Saaber Neutral Newbie July 29, 2003 Share July 29, 2003 Seems like a cat too..... As for the bends, better to leave it as it is, as after straightening it....if the welding is not done nicely, the internal of the pipe would be be as smooth as when it is stock....

Dualie Clutched July 31, 2003 Author Share July 31, 2003 Confirm 2 cats. Anyway, I've installed a extractor and retain the cat below my car. So now only 1 cat My extractor is a customised item. Noise level after installation is mostly normal, although I do notice high pitch whistling sound sometimes. Any idea what may be causing this sound?

Saaber Neutral Newbie July 31, 2003 Share July 31, 2003 It is quite common although not all the time to have high pitch whistling sound at certain rpm range when using aftermarket extractor with rest of the exhaust still original....due to the difference in the pipe diameter at the joint....

Dualie Clutched July 31, 2003 Author Share July 31, 2003 Orrr... At first thought maybe something salah Btw, between thermal wrapping and thermal paint coating, what is Ur personal recommendation? Link to post Share on other sites More sharing options...
Saaber Neutral Newbie July 31, 2003 Share July 31, 2003 Personally, I prefer to use thermal wrapping and I use only one type of wrap which is Thermo Tec... www.thermotec.com come to the meetup tomolo and see how mine is done lah.... Link to post Share on other sites More sharing options...
Dualie Clutched August 1, 2003 Author Share August 1, 2003 So is it right to say that I can eliminate the whistling sound by upsizing the exhaust pipe to that of the extractor? It only happens at abt 2.7k rpm at speed 110km/h. Other rpm or speed no such sound Link to post Share on other sites More sharing options...
Saaber Neutral Newbie August 1, 2003 Share August 1, 2003 yep....same here, mine happens at 3k rpm only.......at first find it very annoying but after that, got used to it liao.... Link to post Share on other sites More sharing options...

Lester Neutral Newbie August 1, 2003 Share August 1, 2003 Header wrap liao with the shipping kind of material. Tot it'd work. wrap til very nice somemore. but seems like it's trapping heat rather than keeping it in and dissipating it out. Rather hot after driving but it cools down very fast after I parked vehicle. Less than 2 mins can put hand on it liao. Seems ok?
