neilsmith Posted February 23, 2013 Posted February 23, 2013 Alright folks im currently running a jperformance exhaust on a stock engine at 229 bhp but been seriously thinking about going forged over the last couple of months and in need of a new exhaustAnyone clued up about exhaust system flow rates etc and whats best on a forged engine runing 1.4 bar of boost?Any help would be appreciatedthanks, Neil.

Jack-CTR Posted February 23, 2013 Posted February 23, 2013 I've been running a blue flame on mine and made 279 at TD @ 1.4 barSounded good and got on track with it (selling said exhaust to ) Quote
Amjad Posted February 23, 2013 Posted February 23, 2013 JPerformance is quite good as it's a rep of the Nur Spec I think, like the Japspeed? Just get the front section made to 2.5" or 3" (if it's 2.25" now that is) Quote
Ct9 Posted February 23, 2013 Posted February 23, 2013 Nur Spec Excellant Exhaust Mate Have It On My Car . Quote
Driver Posted February 24, 2013 Posted February 24, 2013 Anything good flowing (so mandrel bends) with perf-tube boxes (less restriction then chamber boxes) will do as long as its 2.5" or above.Had a blueflame on mine and know a mate who had a japspeed and worked out why they were cheap pretty quickly.

Starbo Moorley Posted February 24, 2013 Posted February 24, 2013 Japspeeds a good system mid pupe and back box are 3" just the front pipe is 2.25" lol easy enuff to get a 3" replacement. Quote
Amjad Posted February 24, 2013 Posted February 24, 2013 I run a Japspeed too and for the money it's very good Quote
iamlegend Posted February 24, 2013 Posted February 24, 2013 dont go japspeed.. had canny few and have to say the blitz nur spec is just awesome!! then the power getter I would say! Quote
Starbo Moorley Posted February 24, 2013 Posted February 24, 2013 The blitz piping is only 2.5inch but thsts fine for the power levels you want. Quote
PaulStarletSR Posted February 24, 2013 Posted February 24, 2013 I've got a fujitsubo powergetter and I've heard they are good for big power Quote
daniel_g Posted February 24, 2013 Posted February 24, 2013 I'd say a backbox of your choice and get some 2.5'' piping made up. Quote
A L 3 X Posted February 24, 2013 Posted February 24, 2013 I've got a fujitsubo powergetter and I've heard they are good for big powerMine with no silencers and td04 is sooooo loud lol. Quote
neilsmith Posted February 24, 2013 Author Posted February 24, 2013 The jperformance one has been a good exhaust but i also found that it sits quite low and sweeps down quite a bit from the de-cat, anyone else found this?Also does anyone know the difference between the blitz nur spec s and nur spec r?Cheers, Neil. Quote
Matt1878 Posted February 24, 2013 Posted February 24, 2013 The Nur spec R is 3" and the S tapers down to 2.5 at the back box...Other than that... Don't think there is much difference.. Maybe the angle? Noticed the R is a lot straighter than the S .. Seems to sit quite low/flat. Quote
PaulStarletSR Posted March 5, 2013 Posted March 5, 2013 Mine with no silencers and td04 is sooooo loud lol. il b joinin u then mate! Quote

Arnold Posted March 5, 2013 Posted March 5, 2013 I've got a modified Blitz Nur Spec on mine. Had an extra flexi pipe put in, and an extra bracket to stop it smashing into speed bumps. Quote
