C63 Full Cat Delete Pipes - Power Gains?
Hey All,
I just scored an amazing deal on a set of primary and secondary delete pipes. I don't know who makes them, but they are new, have nice welds and an X Pipe, bolt up to the factory cat back. Cost $450 CAD
I have a EC V5 tune going on the car as well. My plan is to have these pipes as "test pipes" - car is a summer daily and I don't need the world to hear me, but for the odd drag or track day, why not.
I have really been searching around but I cannot find any concise information of before and after gains. Does anyone know what I should expect? Im not really chasing numbers, just curious. Even if its 2hp I'm happy considering these were 1/10th of headers!
Thanks!

S550 on order
I don't have any cats, there is probably a few HP gain, but honestly just straight pipe your secondaries and be done with it, No cats at all is way to loud and it stinks a lot when you WOT it, it sounds insane for about a month then you start feeling bad because its straight up deafening ..i think cat-less is louder then LTH imo

These pipes are for "test" purposes - meaning I will only run them for a weekend once or twice this summer.
The car already has a 2nd cat delete - I'm actually planning to put it back in to have a fully factory mid pipe.
Really just curious on what gains and possible drop in ¼ time?

Totally got you there bud, I know what you are talking about.

Like Avery said, it's a very..very small if any gain at all. Also if you want your car to be louder (hear more of the sound), lower your rear seats down. Easiest mod ever!

With the Eurocharged V5 tune and full cat delete, most C63 over this side of the pond in UK gain up to between 515 - 535bhp. Quite a range unfortunately due to the amount of variables as discussed in recent thread.
Mine is achieving 505bhp (post calculation) 424whp with tune but with only resonator delete. Both my primary and secondary cat still in.
I will report back when I have LTH fitted with sports cat in a weeks time.

I actually had a chance to get free headers installed, I opted out because I didn't know who made the headers or what I wanted to do with the exhaust after as the straight header through factory catback is too loud and I am not a huge fan of the sound. I did take the car for a test drive and my goodness it was noticeable - so butt dyno results I will say you'll be happy.
I think in the future I would do headers, cats, supersprint rear section

You will definitely get a few extra ponies by deleting the primary and secondary cats. I picked up 5 HP from deleting the secondary's. But note that a proper Long tube setup on the M156 is the best option for exhaust mods.
Equal length headers also improve back pressure and overall flow. Some also believe that the merge collectors play a pivotal role in exhaust velocity and pressure. HP gains are the easy part, having a linear power delivery is a whole other animal. If driving dynamics are important to you, chopping the cats out may not be the best solution.
