We all seem to run into problems when replacing the exhaust. The big problem is finding a crossflow muffler similar with a 13" case like the stock one.
Looking to see if the fullboar has welded sides or rolled. and wish someone had a soundfile for it. Ive heard the afterburner, that thing gets raspy at higher rpm but sounds good.

I looked at the specs of V4164T and the case width and length is the same as my afterburner one. I think I want to keep a close eye on this thread, I would love to hear from someone that gives it a try.

I've lived long enough and replaced enough exhaust systems on cars/trucks to have learned that I will never install any exhaust components that are not made of stainless steel. Must be at least 409, although 304 or 321 is preferred. Those Fullboar mufflers are aluminized steel which is just garbage. You could install one of those, only drive your car on sunny days and never drive through any water on the roads and that muffler would still rot away. It's unfortunate that they created tooling to make these mufflers with varying inlet and outlet sizes, but they don't offer it in stainless.
I have the Flowmaster stainless steel muffler from WCF (although it took a like time from order to delivery), and the muffler is indestructible. It still sounds great after 17 years, so I would vote for stainless, also. bb
Several of us have replaced our exhaust systems and used Spintech mufflers. Ron's 333SC muffler provides a great fit given the limited amount of space available for installation. Another muffler to consider.
how important is the width? does it have to be 13" or is it just easier to replace?
Here's a pic of stock exhaust next to one I built using Flowtech Afterburner muffler - 4"x10"x13" long body (stock 4"x11"x12" long) Note - Afterburner is loud as hell running without catalytic convertor.

OK, so which one is the most quiet? I have a Spintech on my DOHC swap and it's too freakin' loud. I'm looking for the quietest 2.5" crossflow in that case size. Any ideas?
I remain unconvinced that the objective of having unrestrictive flow and a soft sound is possible with a 14" L cross flow muffler. The out-the-back short 3800 systems that I have fabricated have been loud. The 3" Flotech Afterburner with dual 2 1/2" Outs was certainly non-restrictive but very loud and that's with two Hedman Hot tips resonators added. It was just too loud for my taste so I switched to a Spintech 334 SC, that had the some external configuration but circular baffles within. Its about 15% quieter than the Afterburner, a step in the right direction but not low sounding at all. The quiet 3800 systems appear to be the ones using the 21" Magnaflow but the fit is tight and the trunk heat shield needs to be removed . I didn't want to do it this wayso the Spintech stays for now. I will try to use sound insulation on the fender wells and on the deck lid and hope that I can get the interior "radio quiet".

I don't know how much if a business they are or how viable they are. Looks like a big business from the building pictured, but there's only 3 guys there. Online ordering crashes once I input that I'm in Canada (pick new address). When I phone, I always get a guy who says I need to speak to "the other guy" who's never there. He then takes my information so "the other guy" can call me back - but never does...
Too bad because they have the best price on the Jones muffler AND mandrel pipe bends (better than Summit Racing)

Im deciding on muffler choice on my 3800 build right now.havent decided yet but did find a cherry bomb muffler 88117 thats 3 in and 2 1/2 out with 16 body
The 13" cross flow is the easiest install. The ones sold on eBay are perfectly fine on a car not used for every day driving. Only $36.95 and free shipping. Had one on my Fiero for 5 years and its still solid as a rock. welded crossflow muffler

When you say not used everyday for driving I can only assume it is a loud exhaust with drone?
That's the big Camaro muffler with 15" case... PM sent...

Good question. I have the Flowtech Afterburner with cat. convertor AND resonator tips. This one: https://www.summitracing.co...t/parts/big-50363flt Sounds very good outside, but the drone INSIDE downs out the exhaust note between 2500-3500rpm.
Super annoying, can't enjoy radio etc. and why I'm rebuilding my exhaust. A friend put the same Afterburner on his Fiero 3800 s/c after I warned him not to. Super loud.. but he "got used to it"... (..."can you repeat what you said?" lol)
I ordered the Jones V4143T muffler for my Indy SD4 from eBay - 13" case length... (I gave up on Mandrel Bending Solutions after a week of pizzing about with them...) https://www.ebay.com/itm/Jo...p2057872.m2749.l2649
The Jones Exhaust V4132T would be closest to factory muffler

Yes that muffler is loud ( compares to Afterburner) but the same size Spintech with the spiral baffles is only about 15% lower. I currently run the Spintech. My next 3800SC install will use the 13" long welded muffler but with a 3" auger insert at the input and dual 2" pipes on the output. The combination of the muffler auger and 2" (smaller) pipes going out should really suppress the noise without adding significant back pressure. ------------------ " THE BLACK PARALYZER" -87GT 3800SC Series III engine, custom ZZP /Frozen Boost Intercooler setup, 3.4" Pulley, Northstar TB, LS1 MAF, 3" Spintech/Hedman Exhaust, Autolite 104's, MSD wires, Custom CAI, 4T65eHD w. custom axles, HP Tuners VCM Suite.

Thanks for the info. I am in the market for a muffler myself but do not know what my motor is going to sound like currently (still finishing the build). I have taken the cat off the car, I am sure it will be significatnly louder than what it was before.
I ordered the Jones V4143T muffler for my Indy SD4 from eBay - 13" case length... (I gave up on Mandrel Bending Solutions after a week of pizzing about with them...)
The Jones V4143T V-Power muffler I ordered arrived today. It appears to be very well constructed. Pipe connections are 16ga. It is supposed to be quieter than the Jones Deflector muffler (comparable to Flowmaster 40 or 44).
The "guts" of the V-power mufflers are all the same. I photo-edited this cutaway to show how it looks as a transverse. No flat surfaces or sharp corners inside, so supposed to be deep tone without drone/resonance. Yup - you can see light right through between the outlets.

Wow that's a different setup internally, I'm curious what it wounds like.
FWIW, I have a Spintech on my SD4 with no cat. I have no complaints on the sound. The engine is loud as heck, but not so much from the exhaust, its the solid lifters and straight cut gears that contribute as much as the muffler to the noise.
