Question Downpipe decat

Guys

Could I have a show of hands as to a good choice of decat downpipe for my MY00 Classic.

I'm running a prodrive back box and already decatted Hayward and Scott centre

Thanks

Z

Jap innovations. Give Rich a call. Cheaper than all the others and exactly the same.

Default a couple more q's??

Thanks for the replies

H and S seem well respected does this stand for their fitting service as well?

Pete do you think that you are missing any significant gains from using the prodrive box? It sounds like the way I will go on this.

Finally the splitter and open neck.............is this the recognised best design?

Thanks

Mark

I also use magnex decat downpipe and center with Prodrive back box. Quiet when you want to be but sounds like the end of the world when on boost

Hi mate,

when the exhaust was fitted it made the car spool up a lot quicker, and sounded great, I never had it RR with just the exhaust on so cant tell ya what gains it made.

Got a TSL group n back box, TSL de-cat centre and Magnex twin dump de-cat down pipe (MY99) sounds like thunder, lots of pops, bangs and turbo spooling noises.

I have had an H & S d/p on my RB5 for just over a year now and can't fault it. Really improved pickup at low revs and mid range + top end pull. Also had it fitted by H & S and they were excellent - a very professional bunch of guys.
