2G GST's be aware...

[Spoolin98]

Im not sure if anyone else has had this problem or not, but correct me if im wrong. I had my car slammed to the ground when i first put my coilovers on, with my stock exhaust. Later on i had my car raised a bit when i had my camber kits adjusted. When i went to put my 3inch exhaust on, i noticed the stock exhaust was crushed in half right where the exhaust goes over the rear axles. I believe the gas tank crushed the exhaust when i had the car really low. Im just posting this to aware people with lowered cars and big exhuasts to make sure their exhuasts arent being crushed and minimizing exhuast flow. Any comments welcome. Sorry for the long post.

Comments.....Nice car.

BTW.... I never heard of this problem, but will take a peek next time its on the lift....(knock on wood)

Thanks for the comment, i appreciate it.

I searched for threads on this, couldnt find anything. I had my car really low, couldnt get my foot under the front bumper. Once i noticed the stock tiny exhuast was crushed, i didnt take the chance and raised my car for the 3inch. Comments....

I just cant imagine my exhaust being crushed by the gas tank because my car is low, something does'nt add up. Hopefully there are others who know what your talking about and are willing to shed some light.

The exhaust on our GST's runs over the rear axles and under the gastank. When you lower the car, it lowers the gastank but not the axles, so the exhuast gets crushed. I dont see any other explanation for my exhaust being crushed in half right in that location.

 

[UPGRADED2G]

ok....so i should put this on my "to check" list. I have Eibach sportlines and we all know how low those are on a FWD.

That part of the car doesn't even move. There no way it crushed the exhaust. It's press bent from the factory thats why it looks crushed. Either that or someone backed into something with the muffler and bent the exhaust.

What part of the car doesnt move? It def. appears to be crushed, and i never backed into anything and hit the exhaust, neither did the previous owner.

It runs over top of the rear subframe which is bolted to the car. Does not move.

Thats what i mean when i said "runs over the rear axles and under the gastank", by rear axles i was refering to the subframe. And i never said that moved, i said the gastank moves down when you lower the car onto the exhuast.

Are you using your head? If you lower the car everything goes lower. If the gas tank is lower than the exhaust is lower.

I understand that if you lower the car, the exhaust and gastank lower with it. What im saying is, the subframe doesnt lower. If the exhaust is on top of the subframe and below the gastank, and the gastank and exhaust lower, and the subframe doesnt, then the exhaust will eventually hit the subframe and have no where to go so it will start to crush.
There is no reason to ask me if im "using my head", obviously i am. Leave the smart A$$ comments out or dont comment at all.

i looked at my exhaust and i didn't see any crushed piping. i did see a really big bend going around the rear diff..........................................................o'wait my cars a AWD hehehehe..........

you GST guys have no sense of humor :laugh:

 

[GPTourer]

We do, but only when we hear something funny.

My exhaust goes under my rear subframe, as most 3 incers do because there is not enough room to go over it like the stock one. The gap between the body and the subframe should not change even on a lowered car. My exhaust, however, has gotten the hell beat out of it by curbs, low driveways and some speedbumps.

<--------- From a fellow GSTer...and GSX..heheh

I think you must have had a different reason for the crushed exhaust. I have a 3 inch exhaust and my car is lowered right to the ground with no problems. Sorry it happened to you though. But since you have a new exhaust you should be good. Thanks for the heads up though...good looking out.

 

[Gee-Es-Tee]

Hey man is there any way you could provide a picture of the damage to your exhaust? My car is lowered, and getting ready for a full 3" exhaust, and like to prevent this from happening to me.

So, pics would be great! If its not too much trouble, of course!

I think what some people don't realize is how the rear axel/subframe stays the same distance from the ground while the body/gas ank get lower.

No matter what, your axel is always X distance from the ground. That distance is determined by the size of the tires.

The distance the body/gastank is from the ground is a variable of how compressed the springs are and how big the tires are. Consider this distance Y.

The distance between the rear axel/subframe and the gastank/body is Y - X, and that is how much room the exhaust has. When the car is lowered by Z inches, Y is decreased while X remains constant because the tires are unchanged. The new distance between the subframe and the gastank is (Y - Z) - X. There is less room for the exhaust, so it takes less suspension travel to crush the exhaust.

not to take sides but on my wifes mini van i blew both rear struts (off roading, dont ask ) and when the strut collapsed fulled it toatly crushed the pipes between the rear axle and the floor board (2 1/2 pipe wit a 1 3/4 clearence) happed on a town and country minivan, dunno what relavance it has, but it can happed

As soon as i go home next i will, im away at school right now. Im not sure about you guys with exhaust that go under the sub frame, mine is a BR and it goes over the subframe. I dont see how you guys with 3inch exhuasts lower your cars without crushing the exhuast. Like herostar posted above, it makes complete sense. I dont think you can see the crushed part of the exhaust by just looking for it. I didnt see that it was crushed till i took it out.

Dude first of i'd like to know where your geting rear axles from on a GST cuzz there are none on a GST. There are only rear axles on the GSX's. Secondly i'll really dont think that your gas tank could have crushed your exhaust considering that the gas tank sits well above the sub frame. I really think you just might have run over some thing. but i could be wrong.

Beat up on any Honda's lately? :laugh: Watch out for the Honda guys running around with "exhaust crushin" tools They might be trying to slow you down... hehe

And you have no idea what you are talking about either. This isn't Cavalier suspension where the whole axle moves up and down. It is independent rear suspension. Once again the exhaust runs over the SUBFRAME and under the BODY. The gap between the two does not change no matter how far you lower or raise the car. Take it too a shop and have someone show you for gods sake.

Thank you Captain Obvious. It has already been determined that he is talking about the rear subframe.
