my car was tuned on open downpipe and when i daily drive it i run an exhaust made up of 4 extra ft of piping and a resonator on the end of it. would it be bad driving around with the exhaust i have on? like would it effect the a/f and run richer/leaner with it on?

 

It might a little. But the only way to be certain is to hook a wideband up to it and see how far off you are.

so i shouldnt drive around with the exhaust on?

 

I really wouldn't not knowing if its going to lean you out or not. If you get a chance to put a wideband on it then do it . If it must REALLY be on there then I'd say try to stay out of boost.

thanks, bump 4 info

 

No.... you're fine w/ just the downpipe. This guy doesn't know what he's talking about.

so i can run my exhaust and it wont change anything? i daily drive with my exhaust currently and use open dp for the track (it was tuned on open dp)

 

if it was tuned without the downpipe, putting some sort of exhaust on it is only going to make it a TINY bit richer, if any. sounds like you are putting a minimally restrictive (if any) exhaust on, so DONT WORRY ABOUT IT.

i gaurantee you'll have no problems relating to that exhaust. if your car was tuned well. i'd drive the crap out of it. have fun.

 

2nd that, 4 feet of piping and a resonator doesn't sound too bad. are there any bends and what kind (crush or mandre), what's the inner diameter? I wouldn't sweat it honestly. One run through a set of plugs and you'd know for sure

nope no bends, just a flex pipe at the end of the downpipe, a vband clamp holding the piping to it and just a "strait through" resonator on the end of the piping
