Hi people, I just wanted to know an estimate on how much HP should I expect from resonated test pipes on my Z which currently just has a catback exhaust (not dual) 2.75" . Just an estimate is what I'm looking for . Thanks

 

205hp

 

lol

I'd get a true dual exhaust first, then worry test pipes.

But test pipes can range from like 4-11?
Someone correct me.

 

i agree with vnarang get a true dual exhaust first you will enjoy it more.

 

you would be far better off with test pipes vs swapping to a true dual

anywhere from 5-10 whp

 

+1

I don't see anywhere in the OP's post where he wanted to switch to a true dual. Why are people recommending him to switch to something that won't net him any more power than the exhaust he has?

 

sorry i should seen that he already has a catback on the car...so going duals wouldn't really do much sorry

 

oh i thought he was stock. silly me.

 

Personal experience here. I've had ,my tp for a year now and i love them, my nonresonated have ugly *** rasp from 2.5k to 3k rpms but after wards its just a deeper throatier version of the stock exhaust. The power couldn't ask for more.. i do beleive anywhere from 7-10 rwhp it feels really strong.. but thats just me im going to dyno now soon after dropping in my K&N's

 

Any CEL?
