Hi everyone...

does any one have the APS 3" turbo back exhaust? i have had mine installed since 7-9-07. The exhaust i purchased is from GTWORX.... (Andrew is the Hook up there)

Well i have a new issue with the car just started after 3 weeks of VR Performance doing an excellent job installing my OHLINS (Purchased from GTWORX) and brake kit etc etc... ... and now that the suspension is more stiff the drive shaft at the JOINT in the center is grinding into the exhaust...

APS has the resonator right at the coupling. so the bulge is very close... and you can with some force (not a lot mind you) get them to touch....

does any one else with APS exhaust have this issue? does APS know this is an issue with their exhaust? i think the resonator should be push back 3" inches to clear the coupling and thus not grind into the exhaust if they move around...

the drive shaft has play and so does the exhaust...

looking for advice here... track season is coming and i need to make sure this is taken care of...

I will be emailing Andrew at GT WORX who has been most excellent in taking care of all my aftermarket parts... and see if we can talk to APS about the issue...

thanks for your input.

Take a look at PIC I have 4 more coming tomorrow from VR.

you can fix that with a BFH

 

I had to take a small hammer and bang in my resonator from my exhaust so it wouldnt hit.

 

so wait, I have to bend the PIPE to get this to NOT hit the coupling? that is bad... and now if that were the case it might break thru since it's already grind into it 1/8 of an inch...

I have to believe they have a different pipe or a NEW one to correct this... if not that is a horrible engineering design... I was an engineer and that is just poor.

I might replace the drive shaft with a 2 piece instead of the OEM 3 piece... but man i shouldn't have to do that... i have been looking and some of the other exhausts do not have the resonator right at the coupling...

UG....

 

BFH= big f***ing hammer


Honestly it sucks that this is happening to you, but there is no reason to run out and buy a new exhaust, you need to just dent it a little to get the clearance you need, or you could take the exhaust to a shop and have the resonator removed

 

A friend of mine had this same issue with his HKS exhaust, we fixed it by loosening his hangers and bolts from downpipe back and re-tightning them. Turns out it was not aligned correctly and this fixed the driveshaft interferance. Maybe this will help you not sure. Best of luck

 

I had the same problem with the HKS carbon TI
i cut the resonator out and put a peice in place
works like a charm kinda pissed because i paid alot for the HKS and its susposed to be one of the best but whatever!!

 

Yeah i will check those tomorrow.... but i really wonder if that is it...

well i'm hoping APS is interested in this and fixing it... hell if they make a pipe with out it i will buy it... but i just want to fix the issue.

i will be calling GTWORX see if andrew can help me out... see how we fair... i have also contact APS but they might not talk to me since i'm the end user... give me a couple days and i will have some answer for sure...

 

Nope... all the pieces are aligned... and i just removed the bolts from the down pipe and pull it off realigned and reconnected... still the same distance...

there is no play in this, it's designed very very well... just the resonator is 3" to close to the top of that pipe which puts in direct spot of the Coupling...

Andrew emailed me (GTWORX very responsive) gotta love customer service... and we are going to talk to APS.... some how i think i will be able to get this fixed swapped out or hell i will find a replacement PIPE and put that in this ones place... to buy a 2 piece Drive shaft that removes the center coupling is a small fortune...

The story goes on....

 

Ok here are some nice pics i took just tonight after checking all bolts etc... to make sure this was aligned...

Any one else with APS and seen this issue?

 

I had the same problem with my HKS exhaust. The resonator is in the exact WRONG spot and there is NO room to move the exhaust out of the way! If you do a cursory search you'll find that MANY people have had trouble with these different set ups. My O2 sensor was actually in the way from moving the pipe as well. Eventually it ground a hole right through the resonator. You could bang the tube out of the way with a nice ball hammer but to me that was pretty ghetto.

I took my exhaust off after a year of monkeying with it and bought a JIC exhaust... the note is much more subtle and best of all... there's about 2" of clearance from the drive shaft bearing. NO MORE ISSUE!

 

Well APS is suppose to work with me on this one... I would think if you are the manufacture of this you want this fixed and you want to fix any furture ones being released.

I will post this letting the evo world know if APS doesn't fix this at their cost. i spent i nice amount of cash for this... they should correct the problem...

I have been working with GTWORX and Andrew has been working hard for me, but GTWORX didn't make the exhaust so if APS doesn't come thru a new post of the result will hit the main page letting everyone know about the issue and to steer clear.

thanks for the info... but I'm having a HARD time saying ok just bought a 1200 dollar exhaust and less than 1 year buy another... umm no.

 

Well excellent NEWS, Andrew at GTWORX hooked up with APS and BAM! working on a solution...

i will let everyone know what happens... just SO pleased to get in touch with them and start working on this...

i love the exhaust note on it... and i did a lot of reading before i bought it... so i'm very very please we are going have a solution.....

 

We recommend changing the stock rubber bushings on the propeller shaft with the aluminum Beatrush ones to reduce movement of the propeller shaft while in motion. Also upgrading the oem rubber exhaust hangers with something more solid will help with the catback play.
