Newbie with an Exhaust Question...

[mustangnutbcuz]

Hello to all, I am a new guy to this block and I wanted to post my first thread. I am interested in getting some opinions from other mustang fans. I want to change my exhaust on my stock 1999 v6. I want to know whether I should go with a cat back exhaust that connects to the y pipe or whether I should put in an h pipe and true dual exhaust kit. Any knowledge would be greatly appreciated. I look forward to participating in this great site as much as possible.

Thanks again.

An h-pipe would def be better but it's all a cost thing. If you have the extra money go ahead but there is no real big performance difference or shound on a V-6. If you are planning to do a lot of stuff to the V-6 then an H-pipe might be worth it.

The H-pipe on the V6 is worth the extra cost...it makes a mountain of difference in sound...almost makes the v6 sound sexy.

In addition to a set of exhaust pipes, a set of tubular headers and free flowing cone air filter always make for a nice set of upgrades.
However, plan out your goals and your budget depending on whether you're going turbo, supercharger( roots or centrifugal ) or all engine.

i would go w/ a intake first. preferably BBK. then exhaust. every dyno sheet ive ever seen after the intake is installed w/ exhaust the exhaust will always make more power w/ an intake already installed. u wont get the reel power u want from the exhaust w/o intake. im sure a few of u will disagree w/ me but ive seen it many times before.

MAC make Long Tube Headers for ur ride along w/ MAC's H pipe. im also assuming Bassani make somethin for u.

It does not matter which one you install first; you will end up at the same point either way. As for the intake, I disagree. I would go with a K&N intake tube, as they are plastic and tend to resist heat better. Either way, don't expect much from the intake; your biggest bottleneck is the exhaust, on a stock vehicle.

I am also in the same situation. I am hoping to buy a 99 or 00 V6 Mustang this Christmas. I'm only 17 and work at Mcdonalds making $5.25 an hour so I dont have alot of money to spend. Some guy at my school has a 99 V6 Mustang with a mac dual exhaust it sounds pretty bad. I think he has the direct fit cat back exhaust but I'm not sure it might be the true. I dont have that much money so I'm going to get the MAC direct fit exhaust from www.extremeeffect.com

What are you talking about? That statement makes no sense at all! You do realize he is talking about a cold air intake, and not an intake manifold? You will NOT see any noticeable HP increase just by adding a CAI to a car, with or without an aftermarket exhaust. You can gain the same performance (which is minumal) by removing the air silencer and dropping in a K&N panel filter, as you would by installing any CAI kit! You WILL see and feel a HP increase by adding a less restrictive exhaust system. Headers, hpipe, and free flowing mufflers. This should be priority on the list of mods, right after a gear swap is done!

For a V6, I'm gonna go out on a limb and say screw an H or X pipe. True they balance your flow of air, but most of you are refering to your experience with V8s. The V6 firing order is 1-4-2-5-3-6, so the exhaust gases are naturally balanced. The V8's are different and are not balanced, so an H or X pipe would be wanted. I would have your Y pipe cut and run 2 pipes strait back.

Hello HiFlow5 0, you know I've got much love and respect for your knowledge. Hell, you've even protected me against many flaming threads.
But, you gotta take it easy on this kid, I've been keeping tabs on his posts and he appears to be migrating away from the 4 cylinder scene.
The 4 banger kids tend to like the cold air intakes (CAI) and mufflers because they're easy installs. I've trolled threads that drag on for 4 pages juxtaposing the benefits of one CAI over another. 5 hp, NO! 10 hp, NO! your both idiots!!!! 25 hp!!!. You're all wrong 30 hp!!

Hello F23A4Racer750IL, be patient young grasshopper. You will learn much by speaking little and listening plenty. Good Luck and welcome to Mustang country.

I hate to tell you but wherever you heard this is worng. You will never have a V engine with two banks running equal no matter how well built or desgined the motor is.

I just wanted to say sorry for taking so long to post again. But I really appreciate all the help and opinions. I think I'm going to go with the long tube headers and shorty h pipe I saw on rpmoutlet.com. Along with that I'm going to add the true dual exhaust onto the h pipe. rpmoutlet.com also has an intake package consisting of CAI, mass air flow meter, 70 MM throttle body and throttle body spacer. does this sound like a smart move along with the exhaust mods. Again, thanks for the input. mustangs rule.

I got it from a post off of 3.8mustang.com. Still sorda true though. By the way, love your LS1 guide, very funny. I printed it out and showed it to some of my Chevy friends.

Joshta, you really ahve to be careful what you type in forums. Older, more knowledgeable fellows will pick it apart. Make sure you completely understand your own post before making it. Also, quoting another is almost pointless; true discussions happen when two or more knowledgeable people come together to talk on the web, and you never see the best threads throwing around quotes. As for firing order, the V6 will be very similiar to the V8, as both engines are going for smooth idle and revolution, will will ultimately lead to imbalance in the exhaust. A H or X pipe will help out any dual headed engine.
