Exhaust questions on '95 GT
I have a stock '95 GT. I want to get the exhaust in order. Keep in mind, I'm used to driving a '90 Chevy 454SS with a 534ci big block with Hooker Headers, 3" exhaust and 2 chamber flow's. I want my mustang to sound like that (minus the .660 lift cam).
Here are my plans, let me know if I'm smokin' crack or not. I want to get a set of BBK or Bassini 1 5/8" equal length shorties, get rid of all 4 cats and have my local muffler shop build a new dual exhaust with H pipe and 2 chamber flowmasters. The flowmasters will be 3" straight through (no inlet/outlet offset). I'm pulling them from the truck. Will this work? The guy at the muffler shop was afraid removing the cats would hose up the computer. Suggestions? |

Well, I doubt your going to get the Mustang to sound like the big block. In my opinion though, nothing sounds better than a 5.0 Mustang with 2 chamber flowmasters (keep in mind that I've been around a lot of purpose built race cars and street cars).
I would get a set of 1 5/8" unequal shorties, 2 1/2" off road H-pipe, and a set of (2 1/2") two chamber flowmasters. From what I've heard, this setup sounds the best. Also, I would not waste the money on the equal length shorties. They're more of pain to work with (especially when changing the plugs), and the gains with them over the unequal length are minimal. As far as the computer and no catatlytic converters goes, it's different for every car. On some cars, the O2 sensors have trouble sampling the air since the restriction that was once there is now gone. Also, It might cause the check engine light to come on periodically, and you may experience some lean poping every now and again. To avoid this, you could weld some metal tabs behind the 02 sensors (inside of the h-pipe to slow the exhaust stream) or you could get an H-pipe with high flow cats, which will quiet down the exhaust a little bit. That's my $.02 on the subject.

Yeah, what TJR said! I dont think removing the cats will set off your light though on your 95. As for your other question, yeah I think youre smoking crack!.....j/k

Get the BBK long tube headers, they sound alot better IMO, and they are louder at full throttle. I would then just order an off road h-pipe for it. I have never seen a 5.0 have computer problems with no cats.

I don't know if the longtubes would be worth it at this point in time. For the sake of argument, I'll throw in another $.02 (which is about all it's worth).
1. It's a stock mustang, which in my opinion, isn't worth the hassle of the install (especially since it's a sn95 = less room under the hood). Also, we don't know what mods (if any) are planned for the future. 2. We don't know what transmission is in the car. Do they make longtubes that fit around the AOD? Also, If it has a manual tranny, there's the possibility of melting clutch cables. 3. Longtubes may throw off the readings from the o2 sensors since they are located farther downstream than stock (ie exhaust gases being too cool). Even though they work well on your car, does not necessarily mean that they will work on someone elses. My check engine light used to come on all the time due to the absence of catalytic converters. But for some reason, it hasn't came on at all since my head/cam swap. Go figure! If it were my decision, I would go with the unequal shorties, off-road h, and flowmasters.

i went with the bbk 2 1/2" off-road h-pipe and threw a borla catback on it and no joke it makes flows sound almost like a stock mustang its much cleaner, deeper, and much more of a rumble than flows. Borla is very much worth the extra money.

More info
Sorry, here's some more info. It is a stock '95 GT with a 5 speed. Major mods are planned, however I will build another motor and drive this one while it's being built. But the exhaust will transfer. I am planning a 331 stroker for a ProCharger.
I think I've almost decided to go with MAC or BBK longtubes, custom built off-road h-pipe and my old 3" 2-chamber flowmasters. Rad... |
