Sideways? 33 Report post Posted January 6, 2014 Is it worth it? I'd be more interested in performance gains over price... if it doesn't make any extra power, or fill in the infamous torque dip you could give them away free and I wouldn't be interested...!

Mark@Abbey M/S 235 Report post Posted January 6, 2014 Removing the front CAT will always make a gain as the stock CAT is restrictive; Steve's car with a stock exhaust wasnt that far from our Abbey Development car. I not run one on a N/A yet but I am sure it will give a gain , hope to have some data very soon; The one thing we did find out it doesn tmake the car obtrusive like the F20A manifold we have tried on a car.

rob275 1817 Report post Posted January 6, 2014 It looks interesting, i thought the benefit of this was to remove torque dip though? But FI reduces it anyway doesn't it? Share this post Link to post Share on other sites
Mark@Abbey M/S 235 Report post Posted January 6, 2014 Yes but the front cat strangles the car at high RPM so removing the front cat helps the car breath a little easier. modifying the stock header is a cheap deal than fitting a aftermarket header; Share this post Link to post Share on other sites
Special K 442 Report post Posted January 7, 2014 I found that it added bhp and torque on the prototype Mark made for me.. albeit that was with the second cat deleted and a H&S HFC installed to replace it.. Spec K Share this post Link to post Share on other sites

Bfranklyn86 52 Report post Posted March 5, 2017 What was the price estimate for this one, Mark? Does it retain the heat shield? Share this post Link to post Share on other sites
Mark@Abbey M/S 235 Report post Posted March 8, 2017 We haven't done one of these for a long time due to everyone using after market headers. To modifiy your header will be £330-00 inc vat + fitting , yes can keep the stock heat shields Share this post Link to post Share on other sites

Paul 442 Report post Posted March 8, 2017 Sideways, if you haven't bought an aftermarket manifold in over 2 years since you last asked the question, then you've wasted the last 2 years!!! 1 will300 reacted to this Share this post Link to post Share on other sites
Sideways? 33 Report post Posted March 8, 2017 Fair point, although, in my defence, I haven't been able to justify (to SWMBO) spending money replacing perfectly serviceable parts while the warranty is still in place, and since I'll only get one shot - heaven forbid I pick the wrong manifold - I'll take as long as I need to make a decision :-P Also, if anyone else was interested in having this done, I'm sure they'd like to know what they could expect for their money... Lastly, tbh, I'd completely forgotten about this thread until the question of cost was brought up recently... Sent from my E6553 using Tapatalk Share this post Link to post Share on other sites

Aftermarket manifold gains are well documented and there's a host of options to choose from. And they don't impact the warranty on your car, loads of us with that sort of modification haven't had any issues getting warranty work done. 1 Sideways? reacted to this Share this post Link to post Share on other sites

I had a de cat stock manifold put on when I got my sprintex kit put on. Can't tell you if it made a gain as it got tuned with the supercharger. But logic would say taking out a cat that far up the exhaust would certainly improve exhaust gas flow. Certainly heard it more also. This or a aftermarket exhaust over cost of gain I'm sure the results won't be that much between them and this would certainly be cheaper. Share this post Link to post Share on other sites
