Hi, I already have the 15% pulley and Orranje intake installed on my R53.I already have the electronics, but since I only have the original exhaust they have put Stage 1. For Stage 2 I need an exhaust.

Is Direnza a good quality-price option? I really like the sound of the exhaust

Stage? Wassat like? The Direnza has a nice sound but the mounting hardware is made of cheese

stage?

what crap 😂

the stock exhaust will handle 250hp+,

the Direnza is a copy of the Milltek and has a similar muted sound, ok for the price of them, the centre res can become noisy as I've heard on a few but no big deal, actually one of the better sounding budget shiny systems if left with the res fitted, that will let you run a de-cat without being too obvious sound wise,

the mention of stage suggests you're using a generic map? If so I wouldn't trust it at all tbh but that's me, been there, done that, and seen the map tables for it proving what little was changed in comparison to stock, and how far off it was when run up live on the dyno, never good especially with a pulley.

I'd get a cam in there, if a generic map is in it I'd sack that off, and get a custom map to actually protect your motor, if you don't want to change to a better map I'd still add a cam, just opt for a Newman PH1/2 which I can help with, or Catcam street cam perhaps, either to enjoy a stronger low to mid range still opening up the top end a bit more ;O)

Otherwise dependent on your use there are a few fast road options that have a bit more up top perhaps, Newman PH2 being the next up that runs the smoothest out of those available with the highest lift for example, it will also run with no map but you should get it done as it will exacerbate issues up top (4.5k+) if left.

I 've had a Miltek on my car for around 7 years now. I don't know the price difference between Direnza and Miltek but it's been faultless. I have a Dave F, -15% pulley, GP intercooler and the upgraded bypass valve. It made 193 whp at 1320. So approx 221 bhp on standard cam and map.

The difference is big, almost double the money the Miltek.

Will it have more power with Miltek exhaust or will it be equal to Direnza?

Who knows? Some one on here must have a Direnza. I always go with the "Buy cheap, pay twice" view. Plus the Miltek has always had pretty good reviews over the years.

one of the cars I just sold had one, it's 'very' alike the Milltek just with slightly different joints etc, pipe sizing is the same, both are S/S, one is twice the price and a brand name different, the dearer one also has quality issues just as people have written about in the past, people pay just as much for other noisy systems which do nothing for power, just as at 205hp a Milltek or Direnza will do nothing really great here. A manifold might, and I wonder if that's what they mean, I'd change that before a cat back all day long, but that's just me ;O) Pops and bangs isn't power, that clip might appeal to those liking that racket haha, if noise matters to you more then carry on, I wouldn't want the noise or shockwaves personally. If you want performance, my 2p is as above. Drop a cam in and with a good motor you can be at 240+ easy enough just getting it mapped elsewhere properly imo.

I don't want more noise, I just want a little more power. Which part of the exhaust is most important to this? Sport downpipe, decat, manifold, exhaust rest
thanks

Just to echo what carsorbikes said in post 4 regards generic maps, cams etc this is my experience

My car was rolling roaded at 208bhp with an 11% pulley and milltek centre pipe/toyosport backbox combo as well as a ‘stage 2’ superchip bluefin, their take on stages is stage 1 for pretty much stock cars (Will give approx 8bhp extra) and stage 2 for cars with bigger intercooler, smaller pulley etc (will give approx 40bhp more)

not long after the rolling road was done the gearbox went and the car went to captain camshaft, sorry carsorbikes, who under pain of death encouraged me to get a cam fitted too while the engine was out doing the gearbox, after I’d picked up my teeth from his drive after initially refusing he fitted it for me and it’s made a world of difference, however when it went back to the same rolling road to see what power I had gained the car lost 2bhp on the generic stage 2 map, a quick call to Superchips to explain the situation and they sent me an unmarketed ‘stage 3’ program which had been developed for cars with an updated cam alongside the bigger intercooler etc, another rolling road run and the BHP had gone back up to 218, the cam giving me 10bhp more and a lot more free revving top end

Since then the car has had a 15% pulley fitted by Sean as well as a 2nd hand full milltek system which having changed from a cheap system to that is a lot quieter than before which is how I like it for my daily drive (hence why the non resonated pipe on the toyosport was swapped for a resonated milltek pipe)

then to top it off last week the cat went so I’ve got myself a sport manifold and decat pipe to go with the milltek, I’m hoping it’s not going to be too loud though, I’ve got it booked in for another power run on the same rolling road in early September to see what gains I will (hopefully) get with the milltek, 15% pulley and sport manifold fitted

then it’s a trip to 1320 with my 550 injectors for a custom remap, but I can see that being early next year now!

That has actually had me sat laughing to myself.... captain camshaft 🤣

I figure with alot of these things you tend to get what you pay for.

I only went aftermarket with mine as I didn't want to spend the thick end of 800 quid for the OE catback, that of course would be mild steel and just rot out again in several years.....pattern exhausts for these things are a real mixed bag and still not what you'd call cheap in most cases.

I ended up going Milltek as they tend to be looked on favourably by the community and cost wise it was just about acceptable. I did nearly go Scorpion but it appeared to be more expensive and thinner diameter (2.25 inch vs 2.5 of the Milltek) so I bit the Milltek bullet.

Haven't been disappointed so far, mine is non res so it can be a bit too noisy on cold start and at full chat for my liking but on the whole its pleasant enough and am pleased with it...as it's gotten more coked up the sound has improved IMHO...was very loud and a bit raspy to begin with but definitely got better with use. I think the res system would have been too quiet. Has been on the car about a year now with no issues.

I cant comment on Direnza but if it is much a cheaper copy of a Milltek I'd probably avoid it and go for the real thing...or at least a well regarded big brand exhaust.

I’d keep an eye on on ebay for a decent branded 2nd hand exhaust, my milltek cost me £250 delivered, full resonated system and it’s been faultless

As it happens I’ve got a full scorpion system on the convertible mini one that again 2nd hand off eBay only cost £150

there are bargains to be had out there, luckily I fell on my feet twice with both exhausts at less than or around the price if a new budget one
