installed exhaust, now revs jump..clutch slippage?
 

just installed an Apexi WS2 in my 99 lude, previous to this i had no instances of my current problem.

now, when i accelerate a little more than modestly, the revs will jump about 1000 rpm, and hold there until the car catches up.

I havent owned manual long enough to know whether this is a huge coincidence and the clutch has finally started to slip, or if there is something causing the car to over-rev after installing..

I dont really know what else i can say to explain the problem, but it happens across all the gears except for first. and it does it during the low rpm range for the gear.

FTW = help!

Highly doubt the exhaust is causing this. Sounds more like a slipping clutch. given this is a 10 year old car, do you know how old the clutch is?
How many km's on this car? I use the rule of thumb 100K km per clutch. Some people get 160K km's and some people get less than 80K km's on a clutch so YMMV.

Go about 35km in 2nd, shift to 4th and floor it.

Does the rpm go up but the car hardly goes faster? Yes = clutch.

damn... im almost certain that itll do that...

yes, very ymmv. The clutch mainly depends on how the operator drives and conditions the car has to face. On my 93 civic si hatch, my first clutch was changed @ 320k..

Hence your username? :haha:

JK. Typical for me is around 200k

Im almost 100% sure its the clutch...Never in my life have I heard of an exhaust doing that!!
