the best way to quiet it down would be to put cats on it if you dont already have them. im guessing you have a way around the "inspections" since you have LT's and live in Calinam, so if you can pass the visual. idk about the sniffer tho. a good set of borla XR1's would quiet it down some....im not very knowlegable on quiet mufflers tho.

Hmm I'd prefer to just do mufflers, I'm reading good things about the Magnaflow. The stock cats would be pretty restrictive wouldn't they? All those high-flow cats they won't ship to CA.

I don't want this thing to be like a stock car sound, though I definitely wouldn't mind that with whats in it. Just something that will quiet it down closer to a normal sounding stock car with a catback.

My '01 z28 has the slp LM2 and y-pipe, but rest is stock. To me it's actually quiet, and no cop has ever said a word about it. So I don't mind noise, just want it to sound more "legal" lol.

Well after a few years of wanting to get this done I finally did. I did a lot of research and got some in person reviews of a few systems. Thanks to those members that were available for questions.


Here are the details:
QTP longtubes
Magnaflow spun cats
Magnafow 2.5" x-pipe
over axle 2.5" system
2-Flowmaster 1-chamber mufflers
CME

I wish I could have afforded a nice stainless system with mandrel bends but that was way way way way to far ot of budget... Overall I'm pleased with what I got and that's all that matters.

You can see/read the complete details on this exhaust at it's original thread back in 2005. https://ls1tech.com/forums/generatio...re-posted.html

Headers: Jet Hot
Mufflers: Remus SportExhaust aftermarket mufflers for a BMW 850Csi v12 (left & right sides)
Cats: Car Sound High flow
X-Pipe: Hand made Oval 2.5"
X-Pipe Extensions: Oval that transitions to 2.5" round.
Over Axle Pipes: Hand made 2.5" round
Support Brace: Removed the old stamped panhard rod support brace to the frame and custom made a chrome moly tube for more pipe clearance on the drivers side.
Trunk Area Mods: The trunk tub was altered slightly along with the spare tire tub. They have been welded, sealed with OEM seam sealer, and OEM body shutz sprayed. The trunk tub then was painted to match the OEM look.

Does ANYONE run TDs without an x or h pipe? I don't personally like the way they sound and wondered how much difference not having one would make.

CHRRRIS

I do, it sounds great but all I've read here is that the scatter effect from an X or H pipe helps so I was thinking about adding one in some time. For now I'm happy with my set-up though, just need to tuck it up.

campia

was wondering when you were goin to post up some pics/video. exhaust looks awsome and sounds really good. I notice you have an extra brace inbetween the tips. did you buy them like that or have them weld in another one? are you goin to leave the cme panel black or you goin to get it painted?

LS1HIGHLIFE

iTrader: (8)

Thanks! Yeah these tips came with the extra brace welded in there. I remember you saying yours had an issue and you had one put in it. I'm going to get the whole car repainted eventually. For now she's my black and blue bitch, lol! It doesn't look too bad though.....

Vid of my exhaust with the new 6.0. Has a 3" Hpipe right now, but switching to an Xpipe later this week, because the H seems a little raspy, and isn't giving me the smoother sound that I'm looking for. May end up swapping the single chambers for some Super 44's soon, if I still think it's too loud and I want a little deeper and smoother tone.

UMI Performance

I just wanted to post some updated pictures of the TSP true duals installed with the UMI torque arm (Part #2205), torque arm relocation kit and 3-Point SFC's.

x2. Both my cars have UMI LCA's and a PHB. I need to gather up a little cash and buy some SFC's now.

I think I am going to wait on my true dual build so that I can acquire a UMI full length torque arm and a relocation mount. That really sucks too because I've gathered about everything that I need as far as exhaust pieces.

Here's a picture of what I plan on building:



In the picture I've got a 3" flowmaster D-port merge, flowtech warlock mufflers, summit header buddies, and some hedman extensions (just for a few extra mandrel bends). The can of freon was just for contrast, lol... no 12 oz cans around anywhere.

It might be living in a dream world imagining that I can get those warlocks to fit. They're 4.5" tall, 10" wide, and 13" long. I'm not affraid to hammer the crap out of my floor pans, but I think it's still going to be a tight fit between the fuel lines and my Dana 60 rear. Like I said earlier, I'm still rockin the stock torque arm too. Looks like I've got some more saving to do before I can get the full length torque arm

Any of you guys ever relocated your fuel lines? I'm not talkin about flipping the lines (which definitely must be done in my case), but rather routing the fuel lines in a different path so they aren't so close to a full size muffler on the rear passenger seat area.

Here's a link to my true dual build.

Guess it isn't true duals anymore, but I definitely achieved my goals of making the car quieter and increasing clearance.

Sounds almost stock volume wise at idle/low Rpms and doesn't scrape on any normal bumps or driveways.

Sorry, not a fan of the quad tips, these look OK tho IMO.






Big thanks to Roger's exhaust shop in Fontana, CA. Great work, pricing and install time.
