GEE-OTTO Posted September 25, 2008 Share Posted September 25, 2008 what do you have on your LGT ELs or UELs? imagine a 40 Series FM muffler on your car what do you think ? Link to comment Share on other sites More sharing options...

jim1969 Posted September 25, 2008 Share Posted September 25, 2008 EL would be quieter. I have the UEL with stock exhaust and it's noticable. I had TRUST axlebacks a year ago and sold them due to the increase in cabin noise. The axlebacks were made for the JDM Legacy. The reason they sounded louder on the USDM Legacy is because the JDM Legacy has EL headers and the USDM one is UEL. Link to comment Share on other sites More sharing options...
JoeFromPA Posted September 26, 2008 Share Posted September 26, 2008 Anyone running a Grimmspeed Port and Polished stock exhaust manifold w/ or w/o a crossover pipe and/or ceramic coating? For the price, it seems hard to beat. And I would think their treatment would leave the stock durability mostly in place. Joe Link to comment Share on other sites More sharing options...
DogLeggGT Posted September 26, 2008 Share Posted September 26, 2008 Yeah me too, but I would hate to completey lose the boxer rumble... No doubt that the rumble is a nice note. I was a little nostalgic when I put ont he Perrin EL, but got over it pretty quickly. Maybe some vendor could come up with some type of electronic exhaust note modification device. I'd like mine to sound like a shot of bourbon being poured. That makes me happy. Link to comment Share on other sites More sharing options...
whobaru Posted September 26, 2008 Share Posted September 26, 2008 As long as you know all the facts and both sides of the debate I cannot hold your opinion against you. However you can't say ELH ruins the sound of the exhaust note, it simply changes it to something that some ppl like a lot, and some ppl dislike a lot. Likewise, i don't like the boxer rumble anymore, but i don't say its *bad* or *ruins* a good car, i just don't like it and i went for a performance upgrade that also happened to get rid of it as a side benefit. Agreed. Note the IMHO in my post. Link to comment Share on other sites More sharing options...
Drew888 Posted September 27, 2008 Share Posted September 27, 2008 I have the Grimmspeed header w/crossover on order. Should be on the car very soon [URL="http://legacygt.com/forums/vbpicgallery.php?do=view&g=1586"VbGallery/URL] Link to comment Share on other sites More sharing options...
derkahn Posted October 6, 2008 Share Posted October 6, 2008 just put on perrin headers, and the answer is yes... more oomph all around (technical term) ceramic and wrapped and if... they do eventually crack big whoop 10 minutes to weld or $15 bucks to some other guy to weld em.... on that note why didn't perrin make them out of Iconel tubing like these guys did perrin is already charging enough... http://www.thermallogic.co.uk/page3.html ... I am sure these guys charge an arm and a leg for there's but they look niiiiice if its good enough for WRC its good enough for my outback Link to comment Share on other sites More sharing options...
derkahn Posted October 6, 2008 Share Posted October 6, 2008 oops I just did a short search and if they were made of iconel they would cost like $3000 ... Link to comment Share on other sites More sharing options...
Beanboy Posted October 6, 2008 Share Posted October 6, 2008 Since I wanted to keep the car quiet for now with stock CBE, wanted to do everything else at once and get the headaches of pre-turbo leaks out of the way. Went MadDad for coated versions being under warranty, consistently good reviews from NASIOC, and 3-bolt UP/header connection. Also supposed to help with velocity stack near top of UP. NASIOC test did show some gains, so I'm pleased. -B http://www.standardshift.com Link to comment Share on other sites More sharing options...
Drew888 Posted October 6, 2008 Share Posted October 6, 2008 Grimmspeed parts are on and very pleased. These things are a work of art. All parts are coated on the inside and out except the cross-over (flex section maybe?). Anyway, I have nothing but the butt dyno and over stock there is a very noticable midrange gain. A bit stronger from 2.5rpm on up with more noticable ummmft... at about 3.5k (no, come on now...yes it's the turbo spooling - someone was going to say it. More so than before...definately) Clark Turner just sent me a map for it so I'll flash it later tonight.

This is the direction that I'm heading - GS P&P Manifold > GS COP > GS UP (all thermal coated). Not willing to sacrifice the boxer rumble - which everyone knows is what makes a Subaru a Subaru..., but the higher flowing manifolds (and larger COP) into the larger GS UP is proving to be a VG replacement for the stock system/alternative to headers. Price-wise, you're at uncoated header prices, but keeping the cast iron manifolds (with their ability to retain heat w/o cracking) seems to me the best way to go IMO. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...

I have heard that a P/P job on the stock manifolds is a good lower cost solution to headers. Do you have an idea of the gains with a PP job on a set? Is the stock manifold EL or UEL ?

Do you have an idea of the gains with a PP job on a set? Is the stock manifold EL or UEL ? Truthfully, I don't know what you'd gain with a full, thermally coated P&P manifold, COP and UP - possibly 5-10 WHP/TQ, with a protune probably 15-20 maybe more. Stock manifold is UEL, which is what contributes to the boxer burble. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...

I thought I read somewhere as well that the 2.5i has equal length headers. I doubt P&P manifold on an otherwise stock or slightly modded 2.5i would yield much, if any, gains.

Ive heard stock LGT and 2.5is that are silent 2.5i uses ELH - which is what your's has on it stock. GTs and 3.0Rs (I believe - but haven't verified this) use UEL. If you park a 2.5i and a GT next to each other and start and let both idle, while very "quiet" relatively, you'll notice that the GT has a burbling note in its exhaust sound while the 2.5i has a smoother, flatter sound from its exhaust. That's entirely due to the nature of the exhaust manifolds mixing/collecting exhaust pulses. And my apologies for getting your HP/TQ gain hopes up. I didn't realize that you were referring to a 2.5i. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2008 Share Posted October 15, 2008 I think 2005 2.5i was UEL but 2006+ 2.5i was EL, but I might be wrong on this. Btw, 2.5i is much louder than GT under WOT, but that's the nature of the turbo that muffles sound. Link to comment Share on other sites More sharing options...
