Is the factory exhaust good enough to use?
I have a local muffler shop that says he will do a muffler delete, use my factory tips, and install a Magnaflow X-Pipe for $350. For the first few years I only plan on doing an exhaust, CAI, and maybe a tune for my performance mods. I already have plans for another handful of non-performance mods (shifter, tint, AAC lights, springs, stripes, etc) so I have plenty of other places to be putting extra $$$.
The question is….how bad is the rest of the factory exhaust system? I hear some say the factory exhaust is actually very good and flows well. It’s just not very loud. Then I hear other people try to talk up their aftermarket cat-back systems (ex: Magnaflow Comp or SOLO Mach X) by saying the factory exhaust has several crimps in it and their mandrel bent systems will be much better. Otherwise, IMO, those systems are basically the same…..a muffler delete with an X-Pipe. If I go with the local muffler shop’s exhaust do you think the remaining factory system will be bad enough to justify spending the extra $400 - $500? After all, that will cover the cost of my shifter or AAC lights. My gut feeling is…Yes….the aftermarket cat-backs would be better but until I start doing things like adding LT headers or maybe a Cam I won’t really notice a difference. Go with the local shop and use the extra money on my other mods. I should still get a small increase in HP (guessing 15 rwhp) but maybe not as much as the 3rd party cat-back systems (roughly 20 rwhp). What is your take? BTW: This will be my daily driver (although I work from home and only put about 7k a year on my cars). I will have more fun goosing it from stop light to stop light or maybe catching the occasional Mustang/Challenger on the street. I’ll probably go to the track a couple times a year just for fun but not to be super serious.

I think it is good enough but it is :
1- Heavy. 2- Quite. 3- Bulky. I dont think there is big difference in power. Ahmad

If you're not sure, or are wanting to wait till down the road a little bit before modding, look into how much the muffler delete minus the X-pipe would be. Everything gets better once those huge trash cans are off the car Modified exhaust, in most any form you can get is a gift that keeps on giving Been enjoying my Flowmaster setup since the day I got it. Magnaflow's cat-back system sounds AWESOME, I just didn't care for the large exhaust tips.

I replaced my exhaust right after I got the car. American Racing LT w/3" back to axle, used stock t/pipes and mufflers. It really sounds nice. Quite while cruising around town, but when you get on it it is great.

1. Yes...but I think that once the mufflers and H-Pipe are removed it will significantly reduce the weight. 2. Agreed....but not once the mufflers are removed. 3. Not sure I understand that one. Once the mufflers are gone and X-Pipe put into place the only reason it should be coming out would be to completely replace it. I guess my biggest concern is with the so called crimps in the exhaust. Is that really going to cause any kind of a noticeable difference in performance? I doubt it would have anything to do with sound.

When I got my Zoomer's catback exhaust the biggest difference I noticed other than the sound was how much smoother the acceleration was. The throttle response is smoother and it accelerates more evenly and doesn't feel like it's pushing against something. I also love the growling roar it makes when I start the car.
I'm very glad I got mine and couldn't be happier with it.

The factory mufflers are heavy. If you do a muffler delete your car may be a bit too loud for daily driving so I would atleast try to get nice sounding mufflers that flow good. I would recommend the SLP Loud Mouth 2 exhaust because it is just an axle back exhaust. It comes with mufflers, piping and tips, all for 539. It costs alot less than a full cat back exhaust and looks great.

With the new system you can feel the difference; the throttle response is smoother and makes the car feel stronger. The power getting to the rear wheels may be the same but how smoothly it gets there is improved.

If sound is what you're after......

Those of you with clamps don't believe me? When your car is cold, start it up and run it for a few minutes but don't drive it. Shut it down then take a look under the car later and see where the moisture has puddled up under your clamps. That civilized rumble of a quality muffler is worth every penny in permagrins. |

Another question: when you refer to the resonators, aren't you just talking about the H-Pipe? Doesn't the X-Pipe replace that? DAMN.....this is hard to decide!

I did the muffler delete with an added X-Pipe in place of the H-Pipe last week. It cost me $160. The X-Pipe looks just like the Magnaflow X but is not stainless and is an off brand. The setup sounds great! I thought it would be too loud but it's not even close to being too loud. Also, the X-Pipe has definitely helped the throttle response. I can feel the difference.
So yes, I think the factory exhaust is good enough. My take would be do the muffler delete with an X-Pipe. Much cheaper than going with a full after market exhaust. Sounds great and is no where near too loud. The X-Pipe helps the exhaust flow which helps the throttle response. Also, the X-Pipe does not replace the resonators just the H-Pipe. I still have my resonators in place.
