exhaust system pics

[mo diesil]

im about to be fabricating my exhaust system i bought some SS rep headers and have plans to make a exhaust from there, my question is what is the best design/ setup for a 24v swapped car ive heard of people doing a Y pipe after the O2's,
what is the best size piping? whated some of you guys use for mid sections and mufflers
i would kinda like to replicate a track pipe, this is a some what tracked car

Here is what mine looks like... I have factory OBD2 headers to a Y pipe, to 3" mandrel bent pipe all the back. Running a Maganaflow res. and Borla muffler although it's a bit raspy so I am getting a larger magnaflow to try and cut it a bit.

S50B30 euro..

Mine starts at dual 2.25in, merges up to dual 2.5 for cats via long transition cones and then back down to 2.25 for centre section.
Centre has a magnaflow crossover muffler.
Rear section reduces down to dual 2inch. Rear has a dual Magnaflow on the rear also.
The idea is to keep exhaust velocity high as the gases cool. Does it work? Don't know yet.







Rear section is solidly mounted to the car (subframe and chassis rail) hence the flex joints

that is one crazy setup.
lets keep the pics coming, ill be doing mine next tuesday, im really thinking doing a y pipe to either 2.5" or 3", would 3" be to little back pressure though? i do plan to boost it next year,
what are you guys doing for O2 sensors?

[Vtec?lol]

that's an exhaust...

Holy shit. Nice setup man!

I'm running OBD1 so just have the one O2 on the header. As far as size if you go single and are planning on FI then just go 3". I love my setup, enough back pressure to keep up with a Mustang Cobra the other day ;-)

OBD2 headers, just plugged the other O2 port. Seems to run fine w/just one, I guess you could put it in the Y pipe if you want a better reading.
