Well I have been wanting to redo my exhaust for sometime now. I after alot of research I decided on Hooker 1 5/8 LTs since I did not think the MIGHTY 4.8 needed 1 3/4. Luckily some came up in the Classifieds. I bought some 2.5 mandrel J-bends and 3.0 mandrel U-bends, 5" X 14" 3"Round Magnaflow, 5"X18" 3" Oval Magnaflow, Magnalfow 2.5->3.0 Y-pipe, and some collector rings.... The entire exhaust is flanged at the headers, after the Y-pipe and after the mufflers, this way I can remove it easily. I wanted the exhaust to be quiet I am really tired of my old setup. Now it is barely noticeable at idle and anything below 3/4 throttle it is quiet, just a slight hmmmmmmmm noise. But at WOT it still has a really good tone.

My previous setup was semi true dual, stock manifolds, cats, cut the Y junction off and ran 2 pipes into a dual in/dual out magnaflow. After install it I noticed my low end dropped, not to mention it was really loud and annoying. With the new setup the lowend has returned, I have not really done any WOT runs cause it is wet and the tune is way off. My AFR is really lean, so I was taking it easy, sometime this week I will retune it.

It took about 14 hours start to finish to remove the old system and install and build the new system. I only managed to catch myself on fire twice, so that was a good thing, however I did drop a cherry into my armpit that rather hurts.....

Anyways here are the pics.

All the parts gathered up. I cut up all the bends into 45*s and 90*s.


Headers Installed



Y-pipe 2.5 into 3.0







Mufflers Wideband installed after the Y




Tail pipe I might shorten it a little bit so it does not stick out so much






Entire System



Here is the rather crappy vid, I will try to get a better one up soon.. The video sounds kinda raspy, but it is not, it is just the way the video turned out.....

 

very nice. I'd like to hear it with just the round magnaflow, that's kinda what i was looking at doing if I don't get a corsa

 

Ive always wanted to have enough time to build an exhaust like that!!!

that looks nice man!!!!

And sounds good too!!!

 

Thanks for the compliments. I really wanted to grind down and smooth all the welds then paint it but I was just tooo damn tired. Maybe over my Christmas break I will do it..

 

looks good. I know something like that takes time and patience. How much weight did all that add?

 

I have no clue as far as weight, but all the bends and pipe are 16 gauge, so it weighs a little bit more, but I don't think it weighs that much since I was able to move it around in pieces fairly easily, but a guess would be 20-30 pounds more than my previous setup, most of the weight would be the mufflers...

 

did you order the round mag online?

 

Yep I got it on Ebay, I paid $77. It is stainless that is why it cost a little bit more, but only make that size in stainless..

Here is the link

sweet, that's the one I was lookin at. 77 bux isn't bad at all.
How's that AEM w/b? You got it mounted in a gauge pod?

 

I lke the AEM WB, it seems to work fairly well. the readings are more stable now that I mounted it after the Y-pipe. I have it mounted in a Autometer single gauge pod. The fit of the pod itself is kinda crappy, since it mounts to the existing pillar, but I am waiting to order a dual gauge pod when I decide which other gauge I am going to buy. I am thinking about getting a Interceptor Scan gauge.
