im putting 3" exhaust on my car this week. with the pipe being 3", will i see a big difference if i go with mandrel bend? or should i just go with ol' fashioned crush bent? oh yeah, i just put boost on it too. not tuned yet though.

 

Go mandrel and call it a day.

 

im thinkin bout money too. i gotta get it tuned that day also. would it make much more power with mandrel over crushed?

 

if you dont have money right now I'd just tune it with an open downpipe then do a mandrel bent exhaust when you can afford it, or just wait until you have money to do both at once, I bet a mandrel bent exhaust will make a significant power difference over crush bent.

 

thanks man...i will think that threw. how would the sound be running an open dwnpipe?

 

open downpipe is not as terrible as you'd think...for a short while. Its worth it to deal w/ the noise and have a good exhaust...crush bent sucks

 

i should have the flow since im gonna go with the free ware. i will let you know the numbers this weekend. if they dont use crome or crome pro, which free ware should i ask them about?

 

i'd stick w/ Crome (crome pro isn't free) otherwise i'd go w/ Neptune. At DB i could get some version of it, and i guess its good, for a little over $100...not too bad for a top-of-the-line EMS. I think it just didn't have all the options (i dont need them anyway)

 

whats up with uberdata? heard anything about it?

i agree to go with the mandrel bent piping or nothing at all until you can afford it.
lots of good info on management systems on here,just do some searching.

For gentle bends (say up to 20 or 30 degrees) there's only a very small difference in flow. The thing is, Honda-tech has alot of great suppliers that have stupidly low prices on mandrel bends so might as well do it right the first time.

 

tru

 

ive searched through threads about managments and they all seem like they have ups and downs. i guess its all in the TUNER. i was really just asking schister his opinion.

i've bought plenty of bends from them,and had a good experience every time.stainless kit for $75!

you are right that the tuner is very important.any of the systems you listed will work well-you just need to find somebody who really knows how to use them.

the shop told me $275 for 3" mild steel mandrel bent from downpipe to the muffler. how does that price sound?

 

not bad.

it really is alot of work. You gotta cut bends to make diff angles etc. it actually pretty time consuming.

is that them supplying the materials?i'm assuming crush bends?that's not bad for mandrel if that's the case,but muffler shops with mandrel benders are very rare..around here,it's about $150-$200 for crush bent.
maybe ask them about how much it'd be if you supplied the mandrel bent kit,and they did the welding and fitment.
Chris

 

yeah thats them supplying the mandrel and welding it. i guess they might be giving me a deal since im getting it tuned there too. they dont have a mandrel bender either, i guess they just have a stock of generic bends.

in that case,that's not bad at all.i didn't realize it was a performance shop-i thought it was muffler shop.

is there a way to post pics on HT w/o paying for it?

thanks bud

 

just cut angles into the pipe and weld them together. will be alot of welding and work but will be better than crush bent.

 

are you really gonna notice a difference? Stuff like this gets blown out of per portion in my opinion. Unless its some show car that you will have mirrors under and/or running 500+RWHP, its not gonna matter.

Diesel truck running 700hp and 1000+ft lbs at the rear wheel will run a 4" pipe with cat and muffler. I dont think its gonna matter when you are running well into the 500hp range

 

Josh Ross is rocking 650 whp with 3inch crush bend. Crush bends on Turbo cars as long as its big enough isn't as bad as NA. As long as it isnt restrictive(to small) turbo back doesn't matter much. You have to worry about scavanging with na not turbo.
