Exhaust Question for '01 XR6

cm29579 · 03-10-2007, 09:26 AM

Recently bought this car with a standard exhaust. My previous car was an ED XR6 with a 2.5" sports (all I can remember from the rec't was SP250, and $465). Anyway, I notice the new car labours a little up hills (unless you boot it) and doesn't have a good airflow at all, sometimes changing gears mid climb, which is damn annoying.

How big a difference would a decent, $500 range exhaust make on the AU? I really notice the difference from my ED, things like hills, also when you rev reasonably hard then drop off the accelerator (ed = good constant roll, AU = a big pullback on the car), and gearing.....where I found the sports exhaust made the gearbox much more punchy and reactive, where the AU is sedate (no matter econ/adaptive shift/perf modes).

Any help would be good.

Suggest investing a few minutes to drop your cat and see if it has collapsed, blocking your exhaust. Do you know what oil is in it? Too heavy a grade can take a surprising amount of edge off the performance. Not to forget the usual basics - plugs, leads, filters etc.

Once happy with these, consider $600 or so for a flash tuner with generic 98-octane tune as an alternative to the exhaust. At least 2 site sponsors offer these, you can find out more in the sponsors' forums.

The conventional wisdom used to be that you did mods then got a flash tuner and had it custom-tuned on the dyno. Fair enough when a flash tuner cost $995 and tuning was only custom done on the dyno, 2-4 hours @ $125/hr. With the availability of generic tunes these days you can eat your cake and have it too. Enjoy the extra power & torque of a 98-octane tune, add your mods over time, then get a custom dyno tune done to optimise the mods.

on the subject of exhaust i'd go redback and if you can afford it a decent set of extractors. i have advance on my car as they tend to deliver more down low others like pacemaker but they make their power higher up
