Lmc dual exhaust kit(heartthrob)

[jomatt20]

Hey everyone ordered my kit a couple weeks ago and I received everything but the couplers to connect the tubing and mufflers together. The tubing is not flared except for the tailpipe is flared to connect to the muffler, but it's the same size as the outlet on the muffler. Was just curious if I'm missing parts or do I need to buy more.

I am using this kit on my 72. IIRC, all pieces are lfared on one end in order to slip it together. You might eant to give heart throb and or lmc a call. (Lmc will probably be clueless.)

On a side note, none of mine wanted to fit when i first tried. I realized that all of the pieces labelled "RH" were actually "LH" and vice versa. Holefully they straightened that snafu out.

Good luck with that. Lots More Crap (LMC) has the worst customer service in the aftermarket and you just got an exhaust that had been sold to someone else, returned because it was NFG and they sent that one out to you in the hope that you would take being cheated so they wouldn't lose ten bucks!

I bought one of their kits a few years ago. The pipes & flanges would not fit the manifolds. I took it back. I recently bought a carpet for my S10. It fits horribly.

Some things need to be done by pro's ! Exhaust work is one ! Beats crawling around and swearing and throwing s$@t !

Same story here mine did not even come close to fitting and would not work for the last 3ft of the exaust run. Had to get creative and create the last part on my own

[5567Cruiser]

Same for me, all fit except the very end of tailpipes, had to do some minor rebending with a torch.

Called LMC today was told to send pictures of the pipes not having flared ends. Then they would send the pictures to quality-control and see what happens .

[jomatt20]

These people at lmc are starting to tick me off. I was asked to send pictures to them, sent them Tuesday morning and I received an email saying that they received the pics and where going to let me know something in 3-5 days. Figured I'd call today and ask for an update. When I called the lady asked for all my info and when I told her the situation, o I'm sorry sir let me transfer you. After having to explain myself again the lady tell me" ok your pictures have uploaded and I'm gunna go ahead and email them to quality control! Why did I buy this crap?! I think I'm going to bring them to be flared...

I always wondered why installing muffler-in-a-box muffler? I rather take mine to a muffler shop, the nearest/cheapest is 15 minutes away and it takes them a couple of hours to install for a couple of hundred dollars. I wouldn't want it any other way.

The heart throb kit i bought from lmc was around $200. It is mandrel bent aluminized 2-1/2" pipe. I could not find anyone who would do mandrel bent steel. Only stainless steel, over $1k.
Muffler shop could pnly do crush bent pipe. As mentioned above i didnt have any issue other than mislabelled pipes.

Any where I went it was 600 plus to run my exhaust

Just as an FYI, I bought the Hooker Competition dual kit from Summit and am pleased how it went together. It is 2 1/4 mandrel bent aluminized steel with all the hardware.

It's been a while but If I recall, the kit I bought only had two flailed pieces. (One per side) the only flailed piece was the section of pipe that has the curved section that goes around the trailing arms. The other pieces should slide into the mufflers.
I think I also had a problem with the left and right side beefing labeled wrong.
Mine is not welded up yet so I could take a pic for you if needed.

[jomatt20]

Pics would help, thanks.

Found the pic. Now let's see if I remember how to post it....

Just emailed him!

I just finished installing a Heartthrob kit yesterday. It's their P/N 4144SK with stock mufflers and tailpipes exiting at the sides behind the rear wheels. Since my 82 C10 uses 96-00 5.7L Vortec exhaust manifolds, I had to modify the down pipes, so I can't attest to their fit with stock manifolds.

Pros: Thick wall 16 gauge aluminized pipe, smooth mandrel bends, two extra pipe sections for very long wheelbase trucks.

Con: I didn't see any way to make use of the short hangers. They are apparently designed to mount horizontally between clamps and frame rails, but they aren't long enough to do that. So I ended up buying flexible hangers from a parts store, and hung the pipes vertically from a cross rail just before the mufflers, and from the frame rails to the tailpipes.

Also, their "stock" mufflers are on the loud side, and sound more like turbo mufflers. The noise is amplified by the side-exit pipes bouncing sound off cars and curbs. For whatever reason, the kit with pipes that run straight back to the bumper cost more, even though there are fewer bends and should be cheaper to make.

On another note, I used stainless band clamps at the pipe and muffler junctions for ease of future disassembly (6 x $7.97 at Summit)



Overall, I got a lot of nice pipe and two mufflers for a very good price at Auto Accessories Garage. I paid around $218 including shipping using a discount coupon. Total spent was less than $300 including stainless clamps and hangers. Average price at local muffler shops to do the same work with crush bends was $650. And they typically want to weld everything together.

Just an update. I ordered the kit from the place above, auto something or another. It was like $215 shipped. Did the Summit clamps and it fit perfect with the eaton. Pretty close to the panhard bar mount on axle but fit OK. I did end up going to the muffler shop and found some nice brackets that bolted to the truck and welded to the pipe like these http://www.ebay.com/itm/QTY-4-UNIVER...S/360477577686. Made it easy to do but I have a 2 post lift. I think it would be difficult with the hangers they supplied. Over all very happy and Mike was helpful, willing to send a tail pipe if needed, but it wasn't. Sounds good and my girlfriend likes the sound, but she has only driven it twice to work as I have a few bugs to work on since it was a frame off. Mike

Thanks a lot man. I did email Mike and he has been helpful. I may have the wrong down pipe on my manifold. Did you leave in the heat riser valve? I have a delete in place and used the pipe on the left side that had the shortest distance from the manifold to the first bend. I'm on vacation at the moment but when I get back I'm going to crawl under the truck and give it another go. Do some more adjustments. Thanks again for the pics.

I did not use a heat riser or a delete in its place. Let me know if you want any other pics.

[C1ph3r]

Oh. I am also going to get a set of those clamps you used. It will help some I think.

lmc not having a clue?, heheheehehee
