The Goose is honking now!


Recommended Posts

Well.. finally got the tips welded on and snapped a few pics. These mufflers are Dynomax Super Turbos, 2-1/4" in-out. These are the shorter 14" body due to some length constraints I had with the longer than OEM tips I married them to. I bought the tips on Ebay, but found out later I could have bought them online for much less. (live and learn) I put on the mufflers myself, and had a local garage weld on the tips. He used all stainless clamps, hangers and adapters for just $40!

For those of you wondering, these style "resonated" tips do actually tone down the noise of louder mufflers some. I had her out and about for a few days before I could get them set up, and man was it loud! Some of this is probably due to the exhaust not being out from under the rear end also I suppose... Sounded great for a while, but it got old when cruising around. Now it is a nice deep mellow tone at idle and cruising, but has a nice snarl when you open it up!

I couldn't believe what I found when I tore the old rotting mufflers off. The inlet size was 2" but inside the case it imediately necked down to a very restrictive 1.3" dia! What is up with that? Has anyone ever seen this on any mufflers before? I think this would be adversly affecting performance with too much back pressure. The were not OEM I'm sure, but somewhat similar in look. I sure like the new look and sound much better!

I will be needing new mufflers on mine.  What is the part # to those Dynomax's.  Were they difficult to install (bolt on/off?)?

Thanks,

Eric

Part no. of the mufflers I used is 17731. Here is a link to ALL the Dynomax Super Turbo specs...

Again, I used this choice because of length and inlet/outlet requirements with these tips I bought. Note that this is classified as "Sport" muffler, where the 20" is a street. I would imagine those are a little quieter if that is what you prefer and have the room.

I bought the muffs from Summit where they had a free T-shirt and hat promo, they were something like $35 each. Painted them with Por 20 high-temp paint to keep them looking good. They were very easy to install and clamp up. The bending of the adapter pipe and welding the tips on is not something I could do myself though...

I love the way it looks! Those are great looking tips... What polish/wax are you using cars looks like glass! Mike

Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

Where did you get them for $35? The local parts store I called had them for $71 each? The street version were $59 each?

I got them at http://www.summitracing.com/ They have the best prices i could find on them. I checked around locally too, but they were all in the $70 area... Good luck!

Thanks Scotty, I really think the finish on the car looks fantastic too... especially for an 11 yr. old car! I use Meguires wax on my vehicles, have had nice results. ;)

I was looking at this close-up of the rear quarter just now, and was amazed at how good the reflection is... I didn't notice when I took it but you can see a relection of our house, the flag, and even my dog sitting there. Can't see her too well in this scanned image though, black lab blends in pretty good! :D
