Exhaust pipe kits
- Thread starter scotsdale83
- Start date
I have the factory exhaust manifolds and these and love them. Would never put header on unless I was building a race vehicle. Good fit good throaty sound and not a bad price fourth year of DD use still good in Ohio.
i put a hooker header back kit on my truck, it was ok but the piece that goes over the axle was completly wrong and was way to low to the ground, i took it to a shop and had the back peice redone.

Thats kinda what i figured fits ok but something would have to be fixed.
Any one else have any experience with these kits? I would take it to an exhaust shop but they all want a arm and a leg to bend any pipe.

The one from LMC we had to cut the front off but every thing else was fine. Will I go with it again yes when I need another system or replace one on another truck.
I was and am very happy with it.

some kits are better quality than others to, mine was cheap.

I recently bought a Flowmaster kit for my 90 Blazer which included the cat-to-muffler pipe, 50 series muffler, and then tailpipe that exited behind the rear wheel.

I paid around $220 for it, and picked up a cat from Advance Auto for $112 and then some band clamps from Summit, and some 3" hangers to put it all together.
My only problem was that the cat-to-muffler pipe was flared 3" ID on the cat side, so it was the *exact* same diameter as the cat and would not slide into the cat. I bought a 3" OD pipe that was about 8" long from Advance Auto and slid that in between the cat and the cat-to-muffler pipe and put on a band clamp and that was all it needed.
I also used a stock muffler instead of the 50 series and even though it was a few inches longer, and the pipe fix I had to do made it even longer since it would not slide into the cat, everything still came out just fine.

Should be able to get a custom bent system for $200-300 depending on where you go, with muffler/tips. Unless you really want true duals, then you'll pay for another muffler.
In my opinion, you don't save very much doing it yourself. Exhaust is one of those things best done by a pro...and not cause you couldnt' do it, but because they have teh proper tools and experience to do it right, quickly, for cheap.

X2 I priced a True Dual setup on my 83 Blaze and it was 500 out the door for header back 3 inch, 2 flowmasters, two high flow cats and tips.
Not to mention no hassle of doing it
I used the hooker kit on my old 78 as well as hooker headers. It wasn't designed well in fact the collectors that came with the kit didn't even match the headers so i had to buy new ones and weld them on. Like was said before the bends aren't the greatest either, it doesn't seem like much time was spent designing it.
I also did a cat back edelbrock system on my 97 GMC and it worked great!!

I hear you all talk about 3" pipes and to be honest I think you all have been suckered in to their hype. The ones I put on work fine for this old man! I get a good sound and mileage with them and didn't have to pay a shop to make them or put them on.
Yea yea I know less restriction better performance but to be honest use the pipes I have and put an H pipe in to them before the mufflers and you have the same in my book.
Not trying to make any one mad just don't see the extra cost you all spend.

Whenever I've priced kits, I've been able to find a lower price for a local shop to fab a system in. There is usually like 1 in 10 that will do "non-factory" type setups - sometimes you have to ask around.

Its understandable. I quoted both the 3 inch and smaller systems custom and they were the same price from the exhaust shop. 500 either way.

The only shop within a resonable distance from me has done some pretty interesting systems on other peoples trucks. One of my friends has a newer truck 2000 ish. Went and had dual exhaust put on behind the cat with one muffler dual outlets straight out the back. It came out of the shop with the spare tire in the back!! They took it out cause they were to lazy to bend the pipe around it!! Gonna have to look around a little more for an exhaust shop. Probley gonna end up putting my new headers on and trailering it an hour or so to get to a good shop.
Was hoping these kits were some what decent to avoid the shops but looks like its still the best way.

Generally speaking, increasing the diameter of your exhaust above what is stock will change your performance but not always for the best. A properly designed exhaust allows for some backpressure which will help scavenge unburnt exhaust from the cylinders. If you open up the exhaust, you lose that and will usually change your power band to have more HP but less torque or vice versa.
Only turbo engines like unrestricted exhausts. With a turbo, the bigger the exhaust the better. That is because any backpressure prevents the turbo from spinning up.
Or something like that.

I currently have the Dynomax 89004 kit coming.....was on back order when I ordered last week. I figured since I'm running just a 305, the 2 1/4 would be plenty good. I got a couple of the Thrush welded mufflers too. It'll probably be a couple weeks or so before I get to installing all this though.I'll let you guys know what I think of the kit once I get it installed.

That being said what would be optimal ehaust size on a mild 350? I may keep stock manifolds if it would keep numbers better
2.5" duals is lots for a small block.
