tjsmudger 2 Posted April 22, 2010 Report Share Posted April 22, 2010 Bit of a query this, does a full Miltek exhaust system improve the overall bhp of my VR6. My pal said it would improve it by maybe 20bhp?? I don't know, do I believe him or not??? Link to post Share on other sites
b road blaster 0 Posted April 22, 2010 Report Share Posted April 22, 2010 i would be very suprised if it gave more than 4 or 5 extra i'v got one on my 4mo and can't say i can tell any diffrence Link to post Share on other sites
bungy 2 Posted April 22, 2010 Report Share Posted April 22, 2010 I've got a cat back non res on my 4mo and didn't feel any real difference until I decatted and that seemed to free things up a bit. Link to post Share on other sites
Dazdub 0 Posted April 22, 2010 Report Share Posted April 22, 2010 As a general rule its about 8-10% more Link to post Share on other sites
Knightrider 1 Posted April 22, 2010 Report Share Posted April 22, 2010 Have a look at this that I posted a while ago. It's a US test that gives details how a load of exhausts performed. Jetex came joint top. I’ve posted this link elsewhere in The Garage.http://www.newdimensions.com/00_global/06_med/articles/2004-12/index.asp Link to post Share on other sites
xyber 1 Posted April 22, 2010 Report Share Posted April 22, 2010 I've got a full non res, with sports cats on my S4. Alot more torque low down and faster throttle response. Without the cats if would just make it louder really. Link to post Share on other sites
Ben Seabrook 4 Posted April 22, 2010 Report Share Posted April 22, 2010 it will as the test above shows improve it by maybe 4-5bhp but you are never going to notice that sort of an increase tbh !! Link to post Share on other sites
matty.vrt 120 Posted April 22, 2010 Report Share Posted April 22, 2010 one thing you will notice is milltek sound awesome Link to post Share on other sites
thesharkfactor 0 Posted April 22, 2010 Report Share Posted April 22, 2010 i just put a full milltek system AND a stainless manifold (dont know what make), and a k+n 57i onto a vr6 that had a standard system-with a blow at the cat (lol)..car is totally transformed.. throttle response is slightly improved but the big difference is at over 4000rpm, the power surge is stronger and it pulls harder.sound is among the best ive heard from any car. the milltek makes the engine sound someting like an old 6 cylinder 3series e30 BMW. it is certainly not a deep booming bass noise that'll wake neighbours at midnight at any rpm., it does have a lovely note though, you still know its got a stainless exhaust on it when its going!. the k+n makes proper noise too!.. deep and throaty burble. instant noise upon throttle, i love it.the exhaust, manifold and k+n induction has changed my vr6, given it a new lease of life.. totally different car from what it was. i recommend you get a milltek (and a manifold too!)

Gazbarber1982 3 Posted April 23, 2010 Report Share Posted April 23, 2010 I noticed a difference as soon as I fitted a cat back milltek on my VR (Charged) a lot more responsive and felt quicker through the gears with a great noise! :-) Link to post Share on other sites
b19drg 0 Posted April 23, 2010 Report Share Posted April 23, 2010 I run a cat back Miltek with a BMC CDA , deffo made a difference to throttle response and maybe a little low down torque would sugest the 4-5bhp is about right , but the sound is lovely as you can creep through town without being noticed but can make it sing once your on it. highly recomend Link to post Share on other sites
The Monk 50 Posted April 23, 2010 Report Share Posted April 23, 2010 I have a Jetex strait through system and decat. Noise is immense top end of 1st and 2nd....comparable to an Aston Martin DB9 thrape.I've been switching to and from a stock exhaust.The stock exhaust having middle and back box.Sluggish but it doesn't burst ear drums.Jetex system with decat however is great. The throttle response is quicker as is going through the revs. I noticed a veery slight increase in acceleration after going jetex from stock.Keep toying with the idea of 6 branching her too.

tjsmudger 2 Posted April 24, 2010 Author Report Share Posted April 24, 2010 So, would the main factor on changing to independant 'make' of exhaust, be the slight offering of improved torque?I know it ain't going to be into the lambo territory but then again I don't want constant wheel spin, when I power off!!I quite like the standard growl of my de-cat exhaust!But I would never write off the chance of my car sounding like Aston, when I don't have Aston money!!Talking of money, knowledge of prices of said exhausts would be appreciated (full system) and would it be acceptable to try and get a 2nd hand one?? As a guide what's a decent price for 2nd hand one?? Link to post Share on other sites
bungy 2 Posted April 24, 2010 Report Share Posted April 24, 2010 My Miltek non res brand new was £435. Decats I did myself and made money lol. Link to post Share on other sites
Gazbarber1982 3 Posted April 27, 2010 Report Share Posted April 27, 2010 I paid £246 for my non res cat back. Ex display, brand new with all the plastic wraps on it. Ebay rocks! Link to post Share on other sites
