so Im going SR...

[JeremyR]

having an sr is a pain in the ass, if it breaks, you gotta wait around for parts, or hopefully its something that as a US equivalent. but for some people (like me) i dont give a shit. i have another car to DD in if my sr needs work, so it doesnt make a difference to me. if you dont know anything about sr's, or turbo cars, stick with a ka.

ps: everyone knows the true ballers run 5' exhuasts on there sr's.

You gotta have 3" or else your gonna blow your gaskets? You pulling bullshiet from NICO again??? Lets do some thinking here...stock Silvias run 2.5" exhaust, I dont hear them randomly blowing manifold gaskets. Check your info before you start spurting random shiet like that. Your popping your gasket because A) Your shiets warped B) You need better engine mounts C) Your exhaust hangers suck.

Size of you exhaust piping has absolutely nothing to do with it.

To the OP: If your gonna run 2.5 piping, just remember that the straighter the pipes the better and dumb the cat, the cats what causes the most backpressure more than anything.

well like i said ill eventually upgrade...right now i just need a motor in there stat

once done ill upgrade wut i can...not gonna go to crazy ya know

fliprayzin240sx +1 respect good sir....my point exactly...as far as Cat goes though...im thinking of running one of those solonoid...the cylinder looking thing...just to avoid some noise polution

i dunno that cast manifold doesnt warp to easily and neither does the turbo but what would i know ive only seen it happen to everyone i know with an sr including myself, but yes the hangers and mounts dont help the situation either i was just trying to say to avoid further headaches exhaust helps because you want zero backpressure after the turbo, it adds enough as is, also it reduces heat by allowing the gasses to expand, on another note before anything else get rocker arm stoppers because rocker arms actually do come off in those higher rpms despite what others tell you

this is true, after i installed my exhaust, i made 10.8 psi without a boost controller. before it was slightly more than 7psi. it made me happy......

i have rocker arms on stand by, but thanks for clarifying if i really need them....

[tt99ol]

yeah no problem as many people overlook this, my friend just had his head re-built because he didnt have em so i thought i would let you know

[DALAZ_68]

gravy...any specific brand that stands out???

[tt99ol]

nah theyre pretty much all the same but the greddy ones are the cheapest, or the phase2motortrend.com stainless steel ones, they are like $65
