Exhaust Help

[Reese69]

hi

I had a few issues to my exhaust - currently from muffler to cannon ect (from bottomof dump pipe back is off) is off and I wont have time to fix it before next event - ppls have said just bolt a straight pipe on..

car is idling and running fine - havnt flogged it but on idle afr ratio is on mid 10s will this effect my tune or anything?

running rb25det 35/40 highmount all the bits - external gate - running 320kw car was running fine still is I think -

do I need a re tune or try fix exhaust? I didn't think removing that stuff you effect anything.. I am going to replace spark plugs and re upload tune as batteir has been disco (not that that would do it) I don't think..

as I rev it afr go up to round round 13 - just wanna know if it is ok to drive

thanks

that's what I would think - ill give it a full service ect tomorrow and go for a drive -

track car only so sound aint an issue

but thanks

if im wrong anyone let me know

its just lost a fair bit of back pressure thats all...probably why your idle afr's may have taken a dive...what were they before?....don't cook the underside of your car....or gas yourself out though.

I can't comment on the tuning side of things but I know you will gas yourself pretty quickly. 320kw means a lot of exhaust. not to mention heat, potential fire hazard even?

[Reese69]

Gas my self? I might sound stupid but whilst driving the exhaust still sticks out the back so not sure what you mean..

at my last drift day I noticed a lot of drift cars running strsaight pipes..

well my first drive is a cruise session and few squirts so will see how its running after that..

exhaust is tac welded to some suppor bars so not touching anywhere under the car

I was worried about that other stuff cos the way I thought it will have no restriction and gass will just flow out? got me worried now

long as tune is not effected then I will just monitor it and see

[Badgaz]

i read from your OP that you have from the down pipe completely off the car....i think we assumed that you weren't going to bolt a straight pipe on.

[Blackkers]

yeah mate you mentioned dropping the entire exhaust behind the dump. Weld up a straight pipe really is the way to go. plus that config is run by almost everyone anyway it will last you a couple seasons at least if you do it right

[Reese69]

lol sorry guys - yeah I did drop from the bottom of the dump pipe back then have made a 3ich pipe and bolted up - so basically it is a straight through pipe from turbo back

hope I am making sense -
