:thumbup Got my 88SC back from the shop last night after they installed the Dynomax exhaust and I can't believe the difference in the responsiveness of the car, not to mention the sound (thanks Brianlp). Apparently that was one of the problems with the HKS cams, they just weren't able to "breathe" (or should I say "exhale") with the temporary exhaust I had on there (2.25 NA muffler). I'm gong to move the intake out of the trunk to see if that helps the Intake side. The car still seems to smoke some on hard acceleration, but not nearly as much as previously, but it was night time so I can't be too sure yet. I also noticed a big difference in the blue smoke issue after I put the O2 sensor back on. The shop had "forgotten" that I didn't bring it with the new muffler and so they blocked off the bunge! On the one remaining problem---the max out at 6,000 rpm's, the rev limiter cut in at 6500 on the tach so I think the car is revving properly, but the tach is not reading the rpm's correctly? Anyone have some insight on that? TIA

Are you running a header or a cat? I have the KBD header and I've run with and without the cat. I like the way the car sounds at idle and low speeds but it's a bit loud and I don't care for the pitch when you open it up. It sounds a little better with the cat on.
Glad you saw this Brianlp. I'm running the stock exhaust manifold, but I do have an HKS resonator in place of the Cat. I'm very surprised at how quiet it is at idle and cruising, almost like the stock sc exhaust. That's why I was surprised that you said yours was loud. I do love the way it sounds at WOT though and like I said, it really opened up the motor. Thanks for your help in finding the right one. I had it shipped from Summit. Also, I thought I may have incorrectly adjusted the TPS prior to putting the exhaust on because it was "loping", but it cleared right up with the Dynomax.
It is the Dynomax Super Turbo RV muffler from SummitRacing--- WLK-17788 7x31 (similar to the stock shape) $59.99 + shipping.86AW11 said:

Not all that "pretty" but what can you expect from a speed shop with 4 mustangs and a Corvette parked out front? I only had to rethread 2 of the studs from the O2 sensor from the standard nuts they stripped on! (I'll replace the two standard bolts they used to bolt on the flex pipe to the manifold later).

brianlp, add a glasspack. I think you can find them about 11" or so and just hack off the end pipes and weld her in.
the glasspack makes a NICE deep sound, and should make a dynomax turbo sound awesome. I got the sound i want and it sounds better than any NA 2.2 i've heard.

I should have mentioned that I have an HKS resonator in place of the cat. They said they tucked the muffler pretty far up so I don't think there is much more room to get it up higher (Paul, I think it's the angle of the photo that makes it look like it's hanging down so low?) I also just noticed that instead of putting a flange on the end of the pipe leading in to the HKS, they welded the pipe to it! I guess I won't be selling the HKS any time soon.
