ive got a TL ES, and ive been to 2 exhaust centres and they both told me that the current extractor exhaust system is suffecient, as long as i changed the muffler.

ive already done the muffler, was wondering, would it be worth redoing the exhaust before i tune my piggyback ecu? or just leave in stock extractors and piping?

cheers.

The stock exhaust system probably is sufficient, but I wouldn't say the stock exhaust manifold is that great.

If you have a piggy back ECU then definitely go for some extractors, then perhaps some ralliart or RPW cams.

cheers mate.

which are the better extractors, hm, pakemaker, or the rpw ones.

been discussed plenty of times HM headers are essientally ralliart headers Pacies seem to be the go (imgetting a set soon) and rpw seem to be overpriced pacemakers.

if u have an awd pacemaker apparently dont make them to suit i have hm headers only cause they were replaced under insurance and im happy with them made the car feel more free-er

Just dont go the race extractors... all the power is made in the top end. you want it in the bottom end for take off. go the longest tuned length extractor you can find.

Nope, not pacemakers, Liverpool exhausts.
