EXALT Motorsports

After 100k of very hard driving, it was time for some service and maintenance on the Exalt Audi B5 S4. Upon inspection, we determined that the lobes on the cams were flattening and were probably responsible for the misfires we were experiencing at idle. Knowing that we needed to replace the cams, we opted to upgrade to the OEM Audi RS4 cams. However, this time we weren't going to take any chances with wear issues, so we cryo treated the cams prior to install. At the same time, we decided to replace all the valves, valve seats and retainers to address some visual wear and really freshen up the top end. Always looking for that extra bit of power, we Ported & Polished the cylinder heads while they were apart.

At the same time we were working on the Exalt S4, we were building another Stage 3 S4 that needed downpipes, like, yesterday. So what to do? Well, we put the LaBree split downpipes from the Exalt Audi on to the S4 in need and embarked on fabrication of the new Exalt Downpipes for the Audi B5 S4. Sweet, another Exalt part in the marketplace! But boy it didn't come easy; the downpipes weren't finished until 11am the day before the Big SoCal Euro show, meaning at 12noon on Friday, the day before a big show there was no engine in the car... but no worries, by 7pm, we had the satin black Audi started and on a test drive by 8. After the initial test-drive, Exalt co-owner, Derek king, summed up the experience in one word: "butter."
