Adrian14 0 Report post Posted January 4, 2020 Apologies if there’s already a thread about this but I’m new to the forum! I got a GT86 (14 reg) about a year ago and have finally decided I want to do a couple of mods to it. The first thing I’m going to do is put a K&N filter in as it’s an easy one. One thing I want to do is get rid of that brake squeak at slow speeds. Is this just a case of getting different pads? If so what pads would you recommend? Also, would there be any power improvement from just replacing the secondary cat with a high flow sports cat? I want to improve power/reduce the torque dip but want to keep both catalytic converters so it’ll pass an emissions test. Are there any other mods people recommend to get me started? Thanks in advance for your help and sorry for the long post! Share this post Link to post Share on other sites
matrixprotein 33 Report post Posted January 4, 2020 With the brakes you can replace them with any cheap ones from eurocarparts. I swapped out the oem pad for some cheap pagids and they were fine.A high flow cat alone wouldnt be worth it in terms of power gains. Many people go decat with an aftermarket manifold and leave the secondary cat in place and this will pass mot.There are plenty manifolds out there. If new is your things then that's up to you but there are constantly used parts flying around on this platform for you to source.Sent from my SM-G973F using Tapatalk Share this post Link to post Share on other sites
Lauren 2259 Report post Posted January 5, 2020 Stoptech pads are a good option if you want to reduce brake squeal. As has been said, zero gain from swopping one cat for another really. Much better to change the manifold and get a remap. Share this post Link to post Share on other sites
Adrian14 0 Report post Posted January 5, 2020 Thank you for both your replies. Would you recommend getting anything else done in addition to the manifold and filter before a remap? Share this post Link to post Share on other sites
spikyone 139 Report post Posted January 5, 2020 Short of going FI, the manifold is the only significant gain you'll get. Depending on where you live, @Mike@TD.co.uk at Tuning Developments is a good man to talk to. TD sell the manifold, filter, and remap as as a fitted package for a very good price - likely to be less than doing it separately. It was such a good deal that I drove 3+ hours and stayed in a hotel the night before when I had mine done. Lots of people here are running that setup. 2 Burtie178 and Mike@TD.co.uk reacted to this Share this post Link to post Share on other sites
matrixprotein 33 Report post Posted January 5, 2020 I wouldnt even think a filter is necessary but this is up to you. Just the manifold is fine. If going new, then it is correct that going to td will be best value option at approx 1500 all in.On the used market, going manifold and remap can be significantly cheaperSent from my SM-G973F using Tapatalk Share this post Link to post Share on other sites
Adrian14 0 Report post Posted January 5, 2020 Cheers for your help, I’ll have a look into the manifolds. This might be a stupid question but if I decided to get a cat back at a later date, would it need another retune? Or does it not make that much difference Share this post Link to post Share on other sites
MartinT 514 Report post Posted January 5, 2020 The catback makes very little difference to tune or performance. It's just about noise.Sent from my LG-Q6 using Tapatalk Share this post Link to post Share on other sites
Lauren 2259 Report post Posted January 5, 2020 I would get the catback exhaust at the same time. Again if you go to Mike at TD you may be able to get a better deal on the lot. Share this post Link to post Share on other sites
matrixprotein 33 Report post Posted January 5, 2020 Ideally i would prefer to do the whole thing at once as just mentioned. Just to be a little OCD. Sent from my SM-G973F using Tapatalk Share this post Link to post Share on other sites
