my ehaust finally fell apart a couple of days ago (it was pretty much rot near the cat..i bottomed out the car on a speed bump...and well it broke a huge hole) anywayz right now i did a crappy makeshift weld and wraped some mig wire to it to hold it together, now i was wondering what size piping would be best for my civic, its a 1.5l and the only engine mod is intake, also i know a full cat back system would be best but there also pricey, so what type of universal muffler would be best...sorry if any of you know of a decent cat-back setup that wont cost to much cash please tell me....p.s. sorry if i started to ramble
