as in best noise, easiest fit, performance increase, cost etc

also does fitting a BB stuff up the warranty? and I guess there is a need to let insurance co know as well?

and....does anyone have any experience with a dealer fitting a non OEM BB and how much to get it done

Thats all <phew>

Thanks all in advance

Have tried 3 BB's now Scoobysport is loudest with probably largest power increase. Magnex is good sounding quieter than Scoobysport and definatley quieter at high speed. Prodrive quietiest next to OEM has a raspy note not much of a power increase.

Roger, don't know if you're interested but there is a group buy on Blitz exhausts going on at the minute

Magnex offer the great value, sound quality and come with a full lifetime warranty. JIM are also very popular.

tried a few back boxes myself.nicest sound was magnex6x4 with cr4p inner oval removed from tail-pipe but to be honest I felt no performance gain.the blitz is,for me,too loud for road use but without a doubt gave the best gains.

Roger, if you've still got the cats in then I bet you won't notice any performance gain with any BB, unless you confuse it with noise increase of course.

Lose the cats and you'll definitely see an increase though.

Only a prodrive BB will not affect your warranty unless you have a sympathetic dealer. If a dealer fits an aftermarket BB for you then you'll probably be OK.

I went in an STi recently with a full Blitz and it was unbelievably loud - and I'm used to full SS systems.

Then the guy took the baffle out of the BB.....OMG!!!

TSL gets my vote, great noise and has helped stop the overboosting problem on my car. Top quality, well made and lifetime warranty... all this and I got mine second hand. very impressed.
