I have a 1989 civic about to put the si engine into it.. want a cat back so any ideas on top performing ones???

 

please read the exhaust faq at the top of the forums

 

i did man... i want something to rumble hard and give me the best horse power gain... which would you recommend??

 

the hp gains for all exhaust will be roughly the same so let's move on to brands, since that's where the rumble hard part comes in. most, if not all, aftermarket exhaust, offer a rumble. a magnaflow has a subtle rumble, while something like the evo2 has a nice strong rumble. loudness however, is an entirely different aspect of an exhaust. for example, the apexi n1 is ridiculously loud, but it rumbles just like the evo2. really, you should try to hear some exhausts in person.

now, after all this, what's my recommendation? go with a evo2.

 

Go custom, all the brand name exhaust are overpriced. Go to home depot and rent a welder.............just kidding.......but go to midas or something and have them make you a 2.25 inch replacement pipe.......cheaper than buying a 500$+ aftermarket.

 

LOL at home depot and renting a welder...

 

ok but evo2 ok sounds good and it is cheaper to weld my own ok so ya just get the tubing and just buy a good muffler is that right??? cuz you guys lost me lol so i by the tubing and just buy a nice muffler

 

fix your spelling and grammar before you post. it is very annoying and also difficult to understand. anyways, buy the muffler that you want and have the shop do the piping for you. make sure you get mandrel bends and not crushed. the labor (includ. bending and welding) should be about $100-$150 ish and the piping should be $100 ish. the muffler's cost is entirely up to you

 

ok sorry just im working ill check it now... haha but ok sounds good to hear....

 

i have the apexi n1 on my si now and it sounds pretty good. it was incredibly loud when i had no cat on there but when i put it on it sounded deeper and not so ricer ish
