tube lang sir. my car is honda city '04. similar sa ganito yung gusto ko sana gayahin http://farm4.static.flickr.com/3239/...74483101_b.jpg
usually yung mga shops na steel fabricators. mostly the muffler makers. try to google the numbers for mufflerland, theres one in tomas morato or alpan in araneta ave. baka mahal din charge nila.
at times mas better na bumili nung gawa na mismo para sa model ng car mo. it comes with air filter and tube na. sukat pa sa engine mo and yung mga sensor sockets sukat din. yung filter na kasama if you dont want to use it, keep mo muna for your reserve.
