4.0 Exhaust Clip Thread !

*OffTrac* · 09-13-2012, 09:33 PM

Thanks! Wish I could show it off at Gulches this weekend. Still might make it to Durhamtown but I'm not sure yet.

*01STrunner* · 09-13-2012, 09:49 PM

Yeah man. You'll have to let me know how it looks. I think I might just go with the super turbo. I keep bouncing between that and a delta 40

*sport97* · 09-13-2012, 09:55 PM

Super turbo will be much quieter than a flowmaster. A loud v6 sounds terrible in my opinion. The super turbo is about as good as it gets I think. Its deeper and its noticeable but not annoying and loud. Plus the super turbo is way cheaper. I think I paid 35 bucks for mine.

*01STrunner* · 09-13-2012, 09:59 PM

Hmmm on that note definitely leaning towards the dynomax.

*sport97* · 09-13-2012, 10:03 PM

I think you will be pleased. Then again exhaust is very subjective. Everyone likes something different. Lots like the flowmasters, but really a loud v6 is annoying to me. My buddy has a magnaflow on his v6 camaro but on long trips its annoying and doesn't sound all that great. Its to loud for a v6. The dynomax makes it noticeable that its aftermarket without being loud. Offtrac can attest to that verdict i bet.

*OffTrac* · 09-13-2012, 10:49 PM

Amen, amen. I do testify!

*01STrunner* · 09-14-2012, 12:29 AM

I kinda want loud but I agree that loud v6s just sound ricey. I don't think I could handle the drone either as much as I drive with the windows down.

*mr cribb* · 09-14-2012, 07:58 AM

My flowmaster doesn't have the appropriate tail pipe, so it is dumped underneath, therefore creating horrible drone on the highway cruising.

I am betting correct length tailpipe would eliminate such issues.

Opinions?

Video of Super Turbo muffler w/o resonator, dumped right after muffler:

I'm definitely getting more drone. Jury's still out whether it bothers me or not. I notice it but it's not obnoxious and I can't tell if I want to add the tailpipe back or not. I think a tailpipe would help with drone. Someone correct me if I'm wrong.

Been a while, but I did deal with the same exact issue on my '69 Cougar after replacing mufflers and leaving tailpipes off for a week or so. If I remember, the tailpipes did kill the drone as much as you can expect on a 351w on a hardly sound deadened muscle car.

Tailpipes will eliminate in cab drone, it wont sound like your whole vehicle is a damned bee hive. When I did my exhaust I was only able to get the xpipe on the one night, so I had to drive with no mufflers just dual pipes right after the cats. HOLY SH*T it made your head buzz there was SO much drone. The thing to remember is that is is actually not that loud outside of the vehicle because all of the noise is trapped underneath of your truck. Tailpipes eliminate/tone down the drone because they direct the exhaust away from your vehicle and put the noise further away from the cab directing it outwards. It also allows for the exhaust gasses to further cool and slow down, making the sound deeper. 2 1/4" or 2 1/2" is the max you are going to want to go for a tailpipe. The smaller pipe actually makes it sound louder/deeper without making it go WOP WOP WOOOP all over town. You can put larger tips on, that actually tuned my exhaust in. It is deeper at low rpm, loud when you crack on it, but very reasonable at highway speed.

Thanks, that's pretty much how I understood it. Luckily, the muffler is actually past the cab and only under the bed. The drone isn't bad but there was none at all before I cut it off. I think I'm going to put the tailpipe back but keep the resonator out.
