I installed my rv6 j-pipe today with a mechanic.

Driving home, at 3/4-WOT there is an extremely loud hissing sound coming from the exhaust, but I have no idea where exactly its coming from and I personally saw that all bolts and gaskets were tight after installation. I have j-pipe, race pipe, and catback.

I know this can't be normal, any help?

Has to be an exhaust leak.. Check it again with someone on the gas, and listen where its coming from..

How bad is yours? Mine straight up sounds like a turbo...it's very noticeable, but only at wot.

If you staggered the flanges you will get a his no question about it, verify all the flanges are perfect, being off by a little will yield a hiss



That or wait a while till there's carbon buildup wherever you guys screwed up at

Got to be pretty important to mate the flanges evenly, torquing each flange bolt a little at a time to seat the flanges on the gaskets. This is a real common deal on exhaust mating surfaces. Then again ... Al's idea of waiting for the carbon build-up would work as well

oh nah what i ment is wait till its black where there's a leak lol

but um yea you should be going triangular to make sure as you stated that the gasket and flange are dead center

iTrader: (2)

Yea ... I picked up on the sarcasm

Only it doesn't build up, you just hear it when you're going wot.

i hear that after precat deletes. but not the jpipe. two different mechanics, two different shops but found no leak.

Sounds like a gasket leak. May help to loosen up the bolts by the j-pipe and seeing if the gasket is sandwiched in off-center which can cause a leak.

Keep me updated guys I might throw a new jpipe on the car tomorrow and see if i hear anything.

Sure it's not your intake? I'm hearing the suction from the intake more now than I did with the stock setup....

I had mines installed the other day and I noticed that hissing sound too. It was kinda loud at first but after breaking it in, it went away

give it a few days

Richie v6

any updates on this?

TL|GTX

If it sounds like a turbo spooling up, or a blow off valve, then their could be something wrong, thier shouldn't be a noise like this.

Wow...

what does "WOT" mean that i see referred to on these threads often

ifirahse

iTrader: (6)

Yeah it's still doing ti.

My intake makes a whistle, my pulley whines, my exhaust is friggin loud, now this...I'd rather not have it.

Yea I'm going to run it like this for a few days then go underneath the car to see what's going on.

i just got my jpipe/race pipe, havent put it on yet...anyone else having this hissin noise?

stillhere153

iTrader: (1)

After you guys get tired of the hiss, put the car on the lift and line up them flanges


Remember since the pipe now has some miles on it there will be a tiny bit more flex at the section well that's supposed to flex

I just ordered my j pipe + 3rd cat delete today it will arrive Wednesday Ill take pictures of the install, and give you up date.

Oh yeah another thing if i mod my car with exhaust and CAI will that void my manufacture warranty?

pffpffpass

iTrader: (2)

It depends on the dealerships views on mods..

They cant void the warrenty unless it effects whatever is going wrong directly with the mod. But they could find ways around this to F you over..

Ie. If you install an intake, and your heater goes out then that has no correlation. But if you install springs and shocks go out then obviously they will not cover that..

DAMN....i dunno if this is a good thing but just had my j-pipe/test pipe installed and i too have the hissing.....doesnt really bother me but i want to know if it is affexting the performance at all.....i hope not....

Did Richie talk to you about this Saturday? Dunno if things are still going down.

djbonsu

iTrader: (3)

im gonna see what time the shops closes and see if they can re-adjust the gaskets...i hope that helps...doesnt really bother me but it just doesnt seem normal...how does meeting like 6 or 7 sound?

i talked briefly with Richie yesterday when i picked up the pipes and asked aboutt he dyno and he said he would let me know as i think he wanted to dyno his car at the same time as mine but he wanted me to drive it around for a week or so before the dyno. but he did say he was still interested in my dyno results....well see

so call ur cell after the shop finishes looking at my whip??

stillhere153

iTrader: (1)
