Exhausts Vegantune vs. Noblemods

[nickytwohats]

I'd like a new exhaust system. I really enjoy dealing with the Vegantune boys.

Their exhaust looks good

I've seen maps of noblemods/theyellow one vs. standard.

Does anyone have before & after maps on the (amazing sounding) vegantune exhaust?

had Roush and Vegentune the Roush one is better, Trevor has before and after for theirs

i think the Vegantune exhaust has now lost the internal vortex thingy and is even better than it was

need to get it tested and dyno'd

Mine's going to Vegantune next week for its 36 month service. I'd be keen to know what difference there is as I'm considering asking Richard/Gary to put one on mine (decatted, of course).

Had a Roush exhaust fitted last week by Noble London and it not only looks and sounds great, it also improves the performance by 'approx' 40bhp and 40lb torque! (Dyno runs to confirm) It has been very well engineered and comes with an upgraded fuel pump and wiring loom to help prevent lean running after fitting a free flowing exhaust! The ceramic coating option helps to keep heat down, which is a good with the exhaust being right under the Intercooler!

So, in a nutshell, GET A ROUSH ONE! You won’t regret it.

Impressive, what's the dB reading at 3,000 revs?

Not sure, but it is no louder than standard @ Idle, and doesn't seem much louder when driving.....just deeper. (I have CATS on mine but is louder without)!

Anything over 98dbm fails some of UK circuits so I'd be interested to know.

I seem to remember 97db ish with CAT's in.
