View Full Version : Exhaust options

07-23-2010, 12:52 AM
So I've been doing a bit of digging on exhausts.

There's a few options I found. I saw that the st165/185 are the same routing/etc. I don't see a difference in the exhaust routing on the st162 from the st165.I should be able to use the 185's exhaust then on my 162 chassis.

I was looking at the HKS and Motoria exhaust kits for the st185. I can get the Motoria for $450 shipped. It's a full exhaust too (downpipe -> muffler). I would have to have an exhaust shop create the pipe that will come off the cat and over the crossmember back to the rest of the exhaust. HKS I will have to do the same thing.

Now, I found a shop out near me that quoted $195 for a full exhaust, excluding muffler (3" mandreal bend) from the cat back. At first he tried to quote with installing a cat, but I told him that the cat has been moved and is in the front of the car now. He stuck with the $195 quote, half a day to do. I would either run straight pipe (tempted), or buy a muffler and have them weld it on.

I'm thinking the 3" custom exhaust would be the best bet, but I'd need them to throw in a flex pipe as well though. Other than that, I'm finding very little reasoning why I should buy a pre-made exhaust. Any thoughts on this? (namely any recommendations for a muffler hehe).

For example, I'm considering the 60 Series Delta Flow 2.00"IN(C)/OUT(C) Flowmaster muffler . I can get it in 2", 2.5", or 3" sizes. That'll put me just at 300 for a full exhaust.

If they can do a good job (TIG'd, good quality SS, all mandrel bends) and can meet or beat the OTS stuff, then I'd get it done locally.

Hmm the routing between 2wd and 4wd looked different from what i remember. Routing on the 2wd isnt as straight back bc the gas tank is before the rear axle. Id rather have a custom mandrel exhaust anyway bc I have tried an SSAC twin tip and an Aussie twin tip exhaust and both rubbed on the rear subframe no matter how I adjusted it. Im in the process of making my own out of 3in exhaust from an evo that I got for free.

sang has the right idea.
although with the proper wire and sheilding gas mig welded stainless would also be fine.
300 is cheap for a complete exhaust, especially in stainless, and mandrel bent.
hell, just buying the bends to make a complete system in stainless (304 or 316) is over 200$ for me.

Let the muffler shop do it. Did you find a flex pipe for a reasonable price?

Online :P

I've ordered the 3" flex pipe, and will have the exhaust done after a few checks come in (weekly pay FTW). But for now, 255LPH fuel pump en-route!

I'll steal my father inlaws truck for a few days and get the exhaust done.

Just to clarify, the 165/185 and 162 exhaust routing is very different.

For the 162, custom is way better. Cheaper, etc. The big reason the alltrac chassis typically go with pre-fabbed is because most exhaust shops either won't touch it or say it can't be done. (ie. "there's no way a 3" pipe will fit above that axle...."...ya....)

custom would be the best route IMO.

I'm going the custom route.

I can't seem to find a shop that'll do the exhaust a full 3" from the front to the back that doesn't bitch about going over the crossmember. They all want to go under it.

I did some measuring, and the stock st215 cat outlet and midpipe are 2".

I"m going to cut the mid pipe just after the crossmember, and see how that looks. I may go a 3" from the crossmember back and have the shop weld onto the 2" pipe. It's basically a full 3" exhaust, minus like 6" or so.

Does the MP crimp down to less than that though? It won't be a bad thing obviously...stock is like that so it'd be fine, just not maximizing power.

We took the mandrel bends in to a basic muffler shop on Ryan's car....he complained, but he was good about it and did a great job. Just a lot of cutting involved. We should take some pics of Ryan's piping...

I don't think it 'crimps' down, but a different pipe completely. I see there's a weld in there, so I think its a oval pipe in there. I'll know more later today when I get it torn apart :P

It actually bugs me when shops say it can't be done. When you see it completed, it's actually pretty simple. A few extra cuts and welds, but nothing serious at all.
