I am in the process of getting a mandrel bent exhaust made for my '95 manual transmission SC. The system will include a resonator and Flowmaster mufflers. I will have more details in the next week or two but I would like to know if anyone here would be interested in this item. If interest is great enough the fabricator said there would be a price break at 10 and then again at 50. I don't have a price right now but the entire system would be less than $700 plus shipping from the West Coast.

Details about what sort of cat forward mounting issues, what this system will bolt up to, will be forthcoming. In general, though, please indicate whether or not you'd be interested in a system like this.

Thanks for your time.

I'd be more interested in a dual 2.5- single 3.5- dual 2.5

Being new to Thunderbird SCs, why the 3.5 center section, resonator?

Just curious?

Seems to be the perferred system for sound and flow. Dual 2.5" into a Magaflow resontor with a 3.5" outlet past the gas tank, to a y pipe to dual 2.5" with Magnaflow mufflers.

Stainless or aluminized?

I would hope for that price it would be stainless.

I believe it's for stainless. I'll have more info later this week.

Like I said above, the price will be LOWER than $700 probably $600 or less. I'll know more next week.

I am interested in a catless system with downtubes. I need a dual 2.5" system. So, your original post interests me. I plan to reuse my 2.5" mufflers to help offset the increased cost (since I am looking to get a catless system including downtubes). In case they ask, this is going on my off road racing SC. ;)

What type of resonator will you be using, straight thru, crossover, etc..?

Keep in mind the 93-95 exhaust will be different then the earlier models...GAs tank and brake system wise..Unsure if 93 manifolds are same but someone will chime in for sure

Im using 2.5 dual all dynomax Ultraflow with metalllic core cats...With headers sounds great

I'm using stock manifolds, SCP downpipes, custom 2.25" x-pipe exhaust with Flowmaster Super 44s. When it only had Dynomax mufflers the system didn't sound too bad but nothing fancy, however with the Super 44's it sounds amazing.

Just saying, Super 44s are the way to go for sound if you don't mind some volume. :D

I want to say that the fuel tank changed for the '92 model year, and the manifolds changed for the '93 model year. It's pretty early in the morning though, so my memory is a little fuzzy. :)

Manifolds changed for 94-95, all 89-93's are the same.

What ever happened to this?

Price needs to be a lot less than 700 for me to bite if its aluminized pipe.

I am also more interested in a single center pipe after the resonator. I would think we need a couple options for rear mufflers or we can do that on our own if the pipe terminates in a good location.

Thanks,
Todd

Apparently you haven't priced SCP's exhaust system.Aluminized pipes and no mandrel bends and ALL the money. Not knocking them ,but, it seems if this exhaust was mandrel bent and aluminized it would still be a better deal.Especially since the fit on my car still left alot to be desired with the SCP system.

The 92 is also different then the 89-91 cars they also have a straighter pipe in the gas tank area. Knowing what I know now I would've switched to this style before laying out all that cash for the system I bought.

I have priced their systems. I don't know why anyone else here would pay that much for aluminized pipe and those bends.

My point with the price is that it HAS to be cheaper than 600 for me to bite. I know guys in IL that paid 200-400 for a set-up. I have not seen an SCP kit, but the price is WAY too high for that type of set-up in my opinion.

Keep thinking that way about the SCP system because it's outrageously high and told them so after I got it. I bought mine several years ago and was under the impression it would be mandrel bent.I got it before joining this club and I got all my MP stuff (which you now have part of) and the exhaust together on advice from a Super Coupe tuner (not Dave D. by the way) and regretted it. You live and learn though. I was only pointing out that if the bends were mandrel bent it would be an improvement over that.
I'd like to change to the 92 and later gas tank ,but, have been slow to do that after spending so much on that system which does sound really good ,but, had to be modified as it hit in several locations. To be fair SCP outsources the building of the exhaust and they don't even see the one you get so it could be like they said that their usual guy was out and someone else made up mine ,but, I wasn't happy with it.

I agree that the SCP system is WAY over priced. You can go to an exhaust shop and they can fab you up full cat-back exhaust for under $400 just like the SCP one. But again, for $700 you could go to a GOOD exhaust shop and get a mandrel bent stainless steel setup. So like tydlwavs said, for an aluminum mandrel bent setup the price would have to be under $600.

I too looked at the SCP exhaust, saw it was press bent, didn't know what material it was but thought it was way, way too much for a press bent system. I did get their Kooks mid-length headers and down pipes with cats. The exhaust system was an adventure. My parents live in Portland, Oregon and the two places I found on line who offer mandrel bending were in Bend, Oregon and Bakersfield, California.

I called Custom Exhaust Specialties (http://www.4customexhaust.com/homepage.htm) and spoke to Shane Burton who I later found out was the owner. He quoted me a price of $750 installed for stainless 2.5" mandrel bent true dual exhaust with Magnaflow mufflers. My Dad and I drove down from Portland on a Friday, as Shane said it would take a day. It did take a day but I also had them install the headers and downpipes and the header install took far longer than they had planned having never worked on an SC motor before. Being a man of his word he stayed and finished the job. The initial install included a crossover pipe but no resonator. This was loud but not too loud. On the way back to Portland, the drumming in my ear drums convinced me that I needed a resonator.

On the way back to Los Angeles I stopped back and CES installed a dual in out Magnaflow resonator and only charged me for the part. The total price ended up being $900. I have no idea what the price on just the exhaust would be without installation but but it would certainly be less than my cost. I talked to Shane about a group buy and we were going to set up something but because of the long install time for the headers, we didn't get a chance to work on it. He did say that he has a customer with a Thunderbird SC so he could do the mock up on that car if anyone wanted to order an exhaust.

My thoughts:

I bought the SCP down tubes and cats. If you live anywhere near Bend, have Shane make everything. The quality of the work was very, very high. All stainless, all tig welded. Shane and his tech stayed till after 11 o'clock at night because he said he would get the job done in a day even though he still had to take the motor out of his drag boat and be in Eugene the next morning to put it on the dyno. The final job is of the highest quality with no cheap parts. If you have a diesel truck or motor home they can bend up to 4" pipe.

With the SCP cold air system, Kooks headers, SCP downpipes and cats, and the Custom Exhaust Specialties exhaust I got 33 mpg on the Fresno to Los Angeles leg of the trip. The system really allows the car to breathe. The system does not shake, rattle or leak and is easily removable. The system also passed California Smog but only after the tech heated up the system. It seems that with the headers and the cats farther back it's hard for the cats to get hot enough to light off. I drove on the freeway before the test and drove right in. Anyone else might want to really drive for a while and go to a savvy tech.

I will leave it to someone else to do the leg work on this one but be assured that if you do have Shane build you an exhaust, it will be of the highest quality.

I didn't have my camera with me but I did use my dad's camera for some pictures. I'll try to get them uploaded but the school year is well under way and I have no spare time. If I get a chance I'll post a video of the car and what it sounds like. If anyone does take this up, if you mention my name and the car Shane will probably remember.

ill need a setup for my bird right this summer when it get out of my garage i have a 89 and have a 2x2,5 to 1x3inch borla res and dont really have exhaust specialist near where im from! i removed all exhaust system and dont want to put the stock one back! if someone sell a 2,5 to 3 to 2,5 that would fit my borla res i would be really interested!!!i have the stock 89 manifold
