Are spring bolts just as effective as flexpipes? Is one better than the other or do they both do their jobs equally as well..

 

i'm no expert, but i'd say flexpipes are better because they can flex in and out, as well as up and down. spring bolts won't flex up and down very well.

 

anyone else?

like he said

 

Does the size of the flexpipe matter? I went to my local mufller shop and they had one that was about 6-8 inches long and they also had one that was about 3 inches long. I was wondering if the shorter one will work the same as the longer one. I know that the longer one will give it more room to flex but will the smaller one be okay? I love in CA and need a cat on my car so the flexpipe cant be too long..

i got my flex pipe from atp turbo.. and i'm also using spring bolts...

 

our cars come from the factory with springs bolts w/o a flex pipe.

They also come with brackets to support the manifold and A pipe. Most DP setups I have seen do away with the braces. I am a fan of the flex pipe because it provides more play with no sealing issues and can be made in pretty large sizes. I haven't looked into it but I haven't seen a 3" donut gasket w/ flanges and spring bolts for sale.

 

you can use both, or spring tesnion bolts alone should do the job, i think thats how i have it on mine, fomr the factory (on dc2), theres 2 spring tension bolts before/after the cat, and thats how i have it setup with boost.

flexpipe will do or combination of both, too much flexpipe material may distort the flow, so if you go with that, don't use too much.

 

not all. 5th gen preludes use a flex pipe from the factory.

 

So what I've been reading, either one will do the job??

 

If you are still bracing your exhaust on the back of the engine then the srping bolts are fine, otherwise I'd definitely go with a flex pipe. IMO, it's a really good idea to brace the downpipe on the motor no matter what.

 

I think engine mounts will play a role in this also. A turbo motor putting out twice the torque of stock would move more than it's stock counterpart. So if you have more Hp and stock mounts maybe the extra play of a flex pipe would be more appropriate. I'm not sure if this is really a huge issue but I like to use a flex pipe if there are not braces on the DP but would use the spring bolts if it is at least braced behind the oil pan.

 

Theres a little bracket on my dp, where exactly will the brace be welded to for the support? Does anyone have pictures?

 

Just put it on the motor, line it up, tack it in place the weld it up off the car. I woulden't even try to guess by a picture.
