hello everyone.

i want to make a 3" exhaust piping for my ek hatch. and i was wondering which is the best way to build it....(over or under the rear lca?)

pictures will be awesome.... thanks.

 

I think most of the systems go over it, under would cause ground clearance issues IMO.

 

why would you want to get a 3'' exhaust piping. you better get like a 42r turbo or someshit to get a piping that big

 

OVER,

 

Thanks....

,more opinions please...

 

think about it...if u do it under the lower control arm, ur piping will mostlikely hit speed bumps or something...i dont even think i've seen anyone do it under the LCA....

 

hope you have ear plugs.

I would say go over! Going under it will be so close to the ground it will be asking for trouble. There is a reason honda puts it over.

 

over but you do know that you will lose back pressure resulting in a loss of horsepower

 

I really hope he has a big turbo.

 

I have seen a few exhaust systems that go under. I would think the exhaust would get beat up pretty bad. I would suggest going over the LCA. The under the LCA does look kinda cool with the right muffler.

 

i thought the N1 exhaust went under the LCA????????????

not the back pressure argument again

say it with me now.....you do NOT want backpressure. you do want to keep exhaust flow velocity high.

 

back pressure can be good

Thank you!

 

Na or turbo first off. Second go over. Under is a bitch for clearance. I did it once & it sucked. Scraped on everything & flatten. I say always over.

 

thanks for the answers guys...

my current engine is a turbo'd d14..... and the future project is a 400hp b16a2.

 

over ftw

 

According to someone at SCC mag, they say that you need a certain amt. of backpressure to keep the flow from reversing back to the header. Everything is explained here:

This was the wrong place to ask this, some of you guys are ******* idiots.


Over the LCA.

wth back preassure is not good...god

3 inch isnt loud for that one person that said it. its actually quiet it just depends on what you get.

bro runs a 3 inch no cat no resonator and a magnaflow muffler....not loud at all

you dont need a huge turbo for 3 inch....

y0ou would want 3 inchs specially with a turbo casue you do not want ANY back preassure at all so the blades can spin faster....

 

I have a 3" Thermal exhaust on my ls turbo ek-h, run it over the lca, and mine isn't loud, actually quiet low toned and bass'y....until boost of course. Then it's pretty loud. But i'm sure there are those on here that can agree with me, that it's a good loud.

that link just backs up what i said earlier. there are times when backpressure cannot be avoided. you just want to keep it at a minimum.

pointless to argue on the sound because your loud is different from everyone else
