Exhaust

I drive a stock DX (D15b2) in the lighter 91 STD model civic with a few lil mods but nothing to the engine. Tomorrow im getting 2 1/4 in. piping with no Cat. and a universal muffler. Also i have an intake but its longer than short ram, the a/c belt removed, and that lil brass restrictor peice iin the DPFI removed. If anyone could help me on what my 1.4 mile times i can expect with this and what will the hp peak in the pwoerband be at(expected)???

Not to sure about the 1/4 mile time, but if i were you i would HIGHLY suggest you put on a cat. converter on or your cars going to be WAY to loud.

Just my 2 cents

And welcome to the forum:D

17's :)

17 what? curious...I have had people tell me 16s fairly easy from their experience and the ride in it?

You will run low / mid 17's.
a D15b2 wont get you into 16's.

oh thats strange u said that u didnt haev a clue on the quarter mile in ur first post???? come on people reply!! lol

Considering my Si ran 16.7 1/4 mile stock with exhaust.
Then your cx or dx should run low / mid 17's.

I'm pretty sure most people here would agree with that time.

Yea, i would agree with the 17's, a D15B2 isn't gonna get you that far. Keep your cat on there though, if you decide to remove it, at least get a hi-flow cat.

My last car was a 91 Civic hatch STD. I had intake, 2 1/4 exhaust pipping, muffler, and that brass plate removed and managed to run my best time ever with that car... a 18.2. I guess my car looked faster thant it actually was. :licker:

Bisi Ezerioha runs a 1.5L and he hits 11's all motor :P

i ran a best of 17.4 with a stock d15b2 engine, since then I got a 2 1/4" catback custom muffler, I doubt it did much but I would be happy to hit 16's...I will probably go again this summer and see how much it did.

how can you say that you cant expect to run 16's in the car, or whatever you said when it runs a 16.9 to 17 flat stock. I think you will run high to mid 16's

low to mid 17 sounds right. you may hit a high 16 on a cool day with a flawless launch but I wouldnt count on it

did you notice the difference in trim level when that was stated? He said his Civic Si runs 16.7 stock then he said that the DX should run somewhere in the 17s. There is a complete difference between those 2 trim lvls. The Si has a MPFI system, while the DX just has DPFI, i can't remember for sure what the Si stock HP is, but I know the DX is 92 hp.

108 hp...

thank you jeef, i could have looked it up, but too lazy now

If your gonna gut the cat, think about putting a resonator in its place or somethin cause ur cars gonna be hella loud

i got the exhaust on, and i did as i said, cut the cat. off, 2 1/4 inch all the way back and all i can say is......WOW! there is so much difference in power now. it isnt no where near loud as people thought it would, and guess they dont know as much as they think they do.

Maybe I am craxy but I have always thought this would look so cool, with the bumper painted to match the car. But is it possible or even blasphemy. But realy would this work, if so what parts am I going to need?
