gmal ahahahahaha dnt worry about it its fine ahahah

whatnot thanks and
ROFL, no, I don't sit that far back normally (it is for the vid), my head is actually to the right of and behind the head rest so as to not block the video. I also don't drive like that normally with my hands down low on the steering wheel and do the 'shuffle' to turn. Though you can see at 1:12 as I am tail sliding, I don't care as much about blocking the video as I do not crashing lol. I actually ended up using my right side mirror to as my rearview mirror lol. I had a glass/suction GPS mount on my left rear window and stuck my camera in that. The funny thing is as I was moving that to my PC and editing it, I was leaning right the whole time until I noticed lol.

CaptainSlow Nice sound on that vid....
Do you always cruise sitting that far back? I must look like one of those old ladys you see with there face almost in the dash compared to you.
10-21-2010 04:14 PM
whatnot thanks, I put up a new video so you can hear it at idle (skip to 1:30)... though it is pretty quiet any time you aren't WOT.

Gmal, you have any videos inside your car? while driving? I think your video sounds a bit like mine, though maybe a bit louder since you only have 1 and I have two mufflers.
10-21-2010 02:22 PM
gmal wow your car sounds sick!
10-20-2010 07:49 PM
Pmig damn after listening the that, makes me wish i got a 2.0T. but i do love the sound the 3.8 makes.
10-20-2010 07:40 PM
whatnot pmig, yea, sorry, I thought gmal had a 2.0t. And assumed you had a 3.8 since you spoke of true dual exhaust and I never heard of a true dual i4 before, nor a true dual single turbo for that matter. Once you collect into a turbo, splitting isn't really benificial. But I feel I have enough lengh of midpie to scavenge and the split is more cosmetic than anything. I don't think it hurts my performance, but I know it isn't optimal.

I can confirm the muffler is a straight pipe with holes/louvers and it has FG sitting in the muffler can and then it has a "Y" split ine th end and comes out into two outlets.
10-20-2010 07:19 PM
Pmig oh ****, my bad. whatnot you have a 2.0T. ya you did yours the only way you could have. im sorry dude, it thought it was a 3.8. thats what i get for not reading your stuff lol. I am running a 3.8. ya im interested in how yours sounds. setup looks nice.

BTW, glasspack is a generalize term now. modern variations of the glasspacks use steel meshes inplace of fiberglass. there are several different types of those out on the market. fiberglass is just the cheapest.

i wonder what the GC would sound like with a nascar glasspack. haha. my friend had one on his vr-4 galant. it sounded hella good. and loud lol.
10-20-2010 07:17 PM
gmal whatnot ....i think your tips look good ...and i have about 3k on mine n i hear a little but of the rattle but only wehj im in like a parking garage .....n ik what your saying about the dual.....mine starts like 2.5 feet after cat.....n whatnot do you have a video ?
10-20-2010 07:12 PM
Pmig I like the way yours sounds Gmal.

Whatnot, true dual means that there is a one outlet per exhaust manifold/header. we have 2 cats that go to a y-pipe in the cat back exhaust. you run a pipe for each side and run it straight back. get ride of your midpipe with the y's on both sides and run 2 pipes all the way back, one for each side. youll have a true dual exhaust then. for some reason that just came out in a mess. lol sorry.

This isn't really a true dual (if that means stays split from the head), but it is kind of a dual with a glasspack at the tips and it is about 8' behind my hi flow cat. I can keep you posted how long it last, so far it is 6k miles and climbing.



I am still very happy with it though at 2500rpm +/-250 it can drone a bit. I though about maybe getting a resonator in there, but it isn't that bad yet, and it is only in that range which I am not in often enough. I would say the part I like the least is how far the tips stick out, but that isn't too bad either, it just isn't ideal IMO.

gmal yah ik what you mean ....do you like how m,ine sounds ?

not sure, it is trial and error with custom exhaust. I had a glasspack per side on my tib. with the GC having a much larger engine, you may need to put 2 on each side. all i can recommend is to play around with different setups. that is all the aftermarket companies do in R&D. but they are going more for performance applications. honestly I havent really heard any good exhaust. I do not particularly care for the magnaflow sound. it sounds to raspy for me. I like more of a subtle tone till it has a heavy load on it, then the tone needs to be smooth all the way up the rpms.

the performance side comes in at how less restrictive the system is and also the diameter of the piping. you cannot just slap any size dia on the exhaust. you have to retain a little bit of back pressure on the exhaust or you will lose low end torque. you will gain more hp tho at top end. you can build a setup that uses a valve at end that is closed at low rpm when you are needing the back pressure for the torque, and then the valve opens up to free up the pressure to allow more movement as the rpms increase. you get best of both worlds, but like i said, trial and error. not many cars have that exhaust system, but they are out there.

Pmig probably not sadly enough. the exhaust temperature leaving the cat is probably over 1k F. you will toast the fiberglass lol. I am almost tempted to have a true dual exhaust made after the cats and have glasspacks at the tips instead of mufflers. sounded hella good on my tib.
10-20-2010 06:31 PM
gmal well i put mine where the resonator is supposed to be ...like 2 feet away from cat =[ ahahahah ...think it will last more then a year?
10-20-2010 06:25 PM
Pmig Honestly you can get all those aftermarket ones with lifetime warranty and all that stuff, but if you place glasspacks at the end of the exhaust it will last a long time. 7 years on my tib. I left the resonators on my tib and just welded gp inplace of mufflers. loved the way it sounded inside and out. it was actually one of the best sounding exhausts ive ever heard. low tone and not raspy. almost wanted to do that to my exhaust again. still thinking about it.

Fiberglass can handle temperatures well, but at extreme heat, the glass will melt and crystalize into a solid chunk. at that point the fiberglass is easy to shatter. the end of the tailpipe shouldnt be more than a couple hundred degress, which will not degrade the fiberglass packing. The Cat is extremely hot and placing a glasspack right after the cat will degrade it quick. you are talking about over 1000F after the cat. by the time the exhaust hits the end of your tips, it has cooled down substantially. hence why there is condensation dripping from tips.

The difference is, it was placed all the way at the end of the exhaust. The temperatures are not hot enough to burn out the fiberglass. Fiberglass will not deteriorate at 100 degrees. the closer the glasspack is to the exhaust manifold the shorter the life will be. I really wished i recorded some sound clips of my tib with glasspacks before it was wrecked.

can anyone inform me how to upload a sound clip? i found one of what it sounded like inside the car. shame i didnt have one from outside.
