I've got a similar setup on mine... but I need to find a set of tips I like...

LTs, Custom Made X-Pipe, Bullets, and out the sides infront of the rear tires....

Now the challenge... to get rid of the damn leaks....

the 3" pipes i bought from summit were not strong enough to be bent but we bent them anyways, and they have folded somewhat but not too bad. i dont haver any hangers on them, the weight of the system is all on the headers. i ties one side up with a cloths hanger so it wouldnt scrape, and so far its working it does sound badass. and its loud. my dad and my bro think its too loud, but i think its perfect, kind of sounds like my friends 383 monte that runs 11.4's.

I am getting a hesitation when i lightly press the gas but if i push it down harder it kicks into gear. i pulled out my plugs last night the the drivers side ones were all black and the passenger side were all fine. so i replaced them all. what would make my drivers side run too rich? i have the o2 sensors in.

it get some hesitation at real low speeds with my duals and i can tell its running too rich. I'm gonna get it tuned and change the plugs at the same time to see if that helps

I just finished re-doing my dual setup. I stayed with 3" pipes and ditched the bullets for some car chemistry collector inserts. It sounds good and is much lighter.

I used clamps before and always had leaks, this time I welded it and then went over the welds with some muffler mender (epoxy?) and then painted black. No leaks from what I can tell.

I tried routing this out the sides like you're describing but ran into ground clearance issues on my non lowered car. I even ovaled the pipes on a big **** vice but this didn't solve the problem though it did help. I ended up just cutting the pipes off right before the subframes and cuting it on a bevel - to kinda direct the exhaust down rather than straight out. It looks kinda like --> \ but even more horizontal. I know that's probably as clear as mud. Anyways, you can't see the pipe from the outside. I guess the car looks kinda like a V6 now.. hmm.. doesn't sound like it though. Maybe if I took off the Z28 tags I might be able to lure some ricers into play I will say that it sounds good, real good.

BTW, you can get hangers at autozone. Carquest also has a really good selection. What I ended up doing this time (since I had no clamps from which I could hang the thing) was use the doughnuts. If you look around at autozone you'll find a few, I used the biggest - the ford doughnuts. They're a big rubber deal with a few holes/slots punched it them. I ended up using one on each side and so far it hasn't fallen but I'd like to get it better supported. Anyways, all you have to do is find a bolt hole on the body of the car, weld a bolt to a piece of metal and bolt that metal (with the bolt "hanger") to the body. Then weld a bolt onto the pipe and viola. Slide the pipe bolt through one side of the doughnut and the hanger bolt (the one that's bolted or welded to the body of the car) through the other side. Once I figured this out, hanging the exhaust became much much easier. This of course is assuming you have a welder and are at least semi proficient at using it.

I also used some wire temporarily but it rattled like a b!tch, I don't think that's a very good method. You should definately have it better supported. I would think that running it unsupported you run the risk of damaging the LT's - you'll probably break the flange off the collector or something.

If you do stick with clamps I hear band clamps and ball joint clams seal the best. Of course I don't think band clamps are for use with slip fit connections. I'm not sure about the ball joint kind.

Sorry, I haven't got any pictures yet. If there's anything I could clarify just let me know and I'll try and better explain. Good luck getting you setup together.
