Re: Turning in my man card... I want to make the GTRA quieter... best method?
Something like this?
I assume they just slip over the exhuast tip and clamp on? Would they quiet down the exuast to the driver or simply diffuse the sound from being picked up by track monitors?

Re: Turning in my man card... I want to make the GTRA quieter... best method?
I bought the 4" diffuser which fits the 2.5" exhaust. Simply shorten the pipe an inch or so then weld the Supertrapps in place. The diffuser discs can be used to tune the exhaust, less discs less noise or more discs less back pressure but more noise.
Be careful when you put the nuts on the bolts that hold the discs onto the diffusser, they go on with the "marked" side facing out, also use the anti-sieze supplied with the kit. I went with the Supertrapps as an easier way to reduce noise without the hassle of replacing the mufflers. Works for me.

Re: Turning in my man card... I want to make the GTRA quieter... best method?
Hey guys-I'm a newbie on the west coast who just purchased an RA. I have run the car a couple of times at Thunderhill. I would like to run at Laguna Seca which has a noise restriction. I am running the 5.0l Explorer engine which I may change out sometime. For now I don't want to make too many changes until I start to figure things out. I was considering the Supertrapp exhaust tips mentioned in an earlier thread. This would be something I can take on and off as needed without investing into full mufflers (not economical since I could be changing things out later) "Carhauler" can you recommend the correct tips from Summit? Any guess as to what the decibel level might come down to? Any pics?

Re: Turning in my man card... I want to make the GTRA quieter... best method?
I had a motorcycle with the Supertrapps. Sounded great but was loud regardless of amount of plates used. Any feedback on the clamp on option? Would it take the exhaust far enough from the plastic to keep it from melting? Decibel levels?

Re: Turning in my man card... I want to make the GTRA quieter... best method?
I am told Laguna Seca requires 92db on weekdays. (Weekends which are typically sanctioned race days are not meatered) Anybody know if the Supertrapp tips or Superflow mufflers will acheive that? Still concerened about the melting side panel comment on the Supertrapp. Any pics. on the one which is running that way?

Re: Turning in my man card... I want to make the GTRA quieter... best method?
I am also contemplating changing the exhaust and was considering routing to the passenger side for both a better sound (merging 2 to 1) better scavanging and less heat. I haven't seen the pictures from the guy down under/over that routed his this way. Anyone else?

without some serious bends or or the exhaust hanging WAY down I dont see how you could route it without interfering with the driveshaft.

Wess-RA.
Summit Racing part# SUP-444-2503 for $61.00 each are the Supertrapps I use. You do need to be careful when installing them...make sure the difusser is away from the plastic body panels, if not the exhaust heat will burn them. Measure twice, cut once and you won't have a problem. You can also cut an aluminum trim piece to dress up the area where the exhaust exits the body panel. Carhauler
